Mig Voltage & Mig Wire Speed / MMA & Lift Tig Current Control Knobs
MIG Welding Mode
The MIG voltage control is essentially the power in the welding arc that sets the heat. The wire speed feed simply controls the rate at which the welding wire is fed into the weld pool.
For any voltage position setting, there will be a spe-
speed that will give the smoothest and most stable welding arc. The correct wire feeding speed for a giv-
and size, shielding gas, welding material and joint type.
It is recommended to set the welding voltage as desired and then slowly adjust the wire speed until the arc is smooth and stable. When reaching this point, if the penetration/ heat input is too much/ not enough, adjust the voltage setting and repeat the process. If the operator is not able to achieve a smooth and stable arc with the desired heat input for the weld, it is likely that a change in wire size and/ or shielding gas type is required (assuming all other factors are correct).
A chart with recommended settings using this machine for common welding applications is located on the underside 0f the wire feeder cover door and further on in this manual.

Overload Indicator Lamp

Quick Start Guide

MMA/ Lift TIG Welding Mode

The current control knob sets the target welding

output current for either mode selected. The voltage

knob has no

in MMA or TIG mode.

Lift TIG Mode
Lift TIG is an arc ignition system for basic TIG welding that removes the need to `scratch' start or strike the tungsten on the work piece to start the arc, which
to tungsten contamination. Lift arc starting works by gently touching the tungsten on the work piece and
the tungsten is removed from the work piece and send a pulse of electricity through the torch that will cause the TIG arc to initiate.

Electrical Connection
The WT160MP is designed to operate on a 10A 230V AC power supply. If an extension cord must be used, it should be no longer than 10m and be a heavy duty version with a minimum cable core of 2.0mm2. If an extension lead longer than 10m is required, it is recommended to use a Euroquip industrial duty 15A extension lead, part number; #16895.
Operating Environment
Adequate ventilation is required to provide proper cooling for the WT160MP. Ensure that the machine is placed on a stable level surface where clean cool air can easily through the unit. The WT160MP has electrical components and control circuit boards which may be damaged by excessive dust and dirt, so a clean operating environment is essential.

WT160MP Welding Machine

MIG Welding Operation
1. Fitting Wire Spool 1.1 Open the wire feeder compartment door. If using
5kg/ D.200 spool, check that the 5kg adaptor (16) is to the spool holder (17). Fit the wire spool to
spool holder shaft, ensuring that the wire exits the spool towards the wire feeder from bottom the spool. 1.2 Set the spool brake tension by adjusting the spool tension adjustment before replacing the wire spool retainer. The spool brake tension should be set so that the spool can rotate freely, but does not continue to rotate once the wire feed stops. This may need to be adjusted as the wire is used up and the spool weight decreases.
WARNING! Excessive spool brake tension will cause wire feeding
premature failure/ wear of wire feed components.
1.3 Feed the wire from the spool through the wire drive inlet guide (18) into the wire feeder.

3. Adjusting Wire Feed Tension This is accomplished by winding the knob on the tension adjustment lever (19). Clockwise will increase tension, anti-clockwise will decrease drive tension. Ideal tension is as little as possible, while maintaining a consistent wire feed with no drive roller slippage. Check all other causes of excess wire feeding friction causing slippage such as; incorrect/ worn drive roller, worn/ damaged torch consumables, blocked/ damaged torch wire guide liner, before increasing wire feed tension. There is a number scale on the tension adjustment lever (19) to indicate the adjustment position. The higher the number indicated, the higher the tension that is set.
WARNING! Before changing the feed roller or wire spool, ensure
WARNING! The use of excessive feed tension will cause rapid and premature wear of the drive roller, the support bearing and the drive motor/ gearbox.

2. Loading Wire Feeder
2.1 Release the wire feed tension arm (20) by pivoting the wire feed tension adjustment lever (19) towards you from the vertical `locked' position.

2.2 Check the wire drive roller (22) groove matches the selected MIG wire type and size. The drive roller will

groove in use is stamped on the side of the drive

roller. For cored `soft' wire, such as that used in

gasless MIG welding, the drive roller groove has a

serrated

(known as knurled). For solid core

`hard' MIG wire, the drive roller groove used has a

the drive roller by rotating anti clockwise and removing the drive roller retainer (21).

2.3 Once the correct drive roller (22) is selected and and the drive roller retainer (21) is secured
in place, manually feed the wire through the wire drive inlet guide (18), through the drive roller groove and into the outlet wire guide tube. Ensuring that the wire is correctly seated in the drive roller groove, replace the wire feed tension arm (20) and lock it into place by pivoting the wire feed tension adjustment lever (19) back to the vertical position.

3.1 Check that the correct matching MIG wire, drive roller (22) and MIG torch tip are
3.2 Connect the machine to suitable mains power using the mains input power lead (13). Switch the mains power switch (14) to `on' to power up the machine. Set the welding mode switch (7) to `MIG' position.
3.3 You are now ready to feed the wire through the torch. With the wire feeder cover open, pull the trigger of the MIG torch to check that the wire is feeding smoothly through the feeder and into the torch.
3.4 Set the wire feeding speed knob (5) to maximum. With the torch tip removed from the torch and the torch laid out as straight as possible, depress MIG torch trigger until the wire feeds out through the end of the MIG torch. Replace the tip on the MIG

7.5 Select the required output current using the current control knob (5). You are now ready to weld!

WT160MP Welding Machine

NOTE: The WT160MP is a DC (Direct Current) output welder only, this means that it is unable to TIG weld reactive metals such as Aluminium alloys and Brass (which require AC output). DC TIG output is suitable for steel, stainless steel and copper. The New Model is the model in the range that is designed for TIG welding Aluminium and its alloys.

Tips & Tricks
Duty Cycle Rating
Welding duty cycle is the percentage of actual welding time that can occur in a ten minute cycle. E.g. 20% at 160 amps - this means the welder can weld at 160 amps for 2 minutes and then the unit will need to be rested for 8 minutes. All duty cycle ratings are based on an ambient air temperature of 40°C with 50% humidity, which is the international standard for such a rating. In an environment with temperature s exceeding 40°C, the duty cycle will be less than stated. In ambient temperature less than 40°C, duty cycle performance will be higher.

section (GMAW and FCAW), with the intention of providing the very basic concepts in MIG welding, where a welding gun is hand held, and the electrode (welding wire) is fed into a weld puddle, and the arc is shielded by a gas (GMAW) or cored wire (FCAW).

www.weldtech.net.nz 11

Gas Metal ARC Welding (GMAW).
This process, also known as MIG welding, CO2 welding, Micro Wire Welding, short arc welding, dip transfer welding, wire welding etc., is an electric arc welding process which fuses together the parts to be welded by heating them with an arc between a solid continuous, consumable electrode and the work.
Shielding is obtained from an externally supplied welding grade shielding gas. The process is normally applied semi automatically; however the process may be operated automatically and can be machine operated. The process can be used to weld thin and fairly thick steels, and some non-ferrous metals in all positions.

It is commonly used to weld large diameter elec-

electrode diameters in all positions. The process is used to a lesser degree for welding stainless steel and for overlay work.

CAUTION! Do not pull the welding gun back when the arc is established. This will create excessive wire extension (stick-out) and make a very poor weld.
The electrode wire is not energized until the gun trigger switch is depressed. The wire may therefore be placed on the seam or joint prior to lowering the helmet.

ences the width of the weld and penetration of the welding run.
MIG Welding (GMAW) Variables Most of the welding done by all processes is on carbon steel. The items below describe the welding variables in short-arc welding of 24gauge (0.024", 0.6mm) to ¼" (6.4mm) mild sheet or plate. The applied techniques and end results in the GMAW process are controlled by these variables.
Preselected Variables Preselected variables depend upon the type of material being welded, the thickness of the material, the welding position, the deposition rate and the mechanical properties.
These variables are: · ofTeypleectrode wire ·of Seilzeectrode wire · ofTgypase · Garsate

Primary Adjustable Variables These control the process after preselected variables have been found. They control the penetration, bead width, bead height, arc stability, deposition rate and weld soundness.

They are:

· Arc Voltage · Welding current (wire feed speed) · Travel speed

Secondary Adjustable Variables These variables cause changes in primary adjustable variables which in turn cause the desired change in the bead formation. They are:
1. Stick-Out (distance between the end of the contact tube (tip) and the end of the electrode wire). Maintain at about 10mm stick-out
2. Wire Feed Speed. Increase in wire feed speed increases weld current. Decrease in wire feed speed decreases weld current.

3. Nozzle Angle. This refers to the position of the welding gun in relation to the joint. The transverse angle is usually one half the included angle between plates forming the joint. The longitudinal angle is the angle between the centre line of the welding gun and a line perpendicular to the axis of the weld. The longitudinal angle is generally called the Nozzle Angle and can be either trailing (pulling) or lead-

Establishing the Arc and Making Weld Beads

Before attempting to weld on a

piece of

work, it is recommended that practice welds be

made on a sample metal of the same material as that

The easiest welding procedure for the beginner to experiment with MIG welding is the position. The
positions.
For practicing MIG welding, secure some pieces of 16 or 18 gauge (1.5mm or 2.0mm) mild steel plate (150 x 150mm). Use (0.8mm) cored gasless wire or a solid wire with shielding gas.
Setting of the Power Source Power source and Current (Wire Speed) setting requires some practice by the operator, as the welding plant has two control settings that have to balance. These are the Current (Wire Speed) control and the welding Voltage Control.
The welding current is determined by the Current (Wire Speed) control, the current will increase with increased Current (Wire Speed), resulting in a shorter arc. Less Current (Wire Speed) will reduce the current and lengthen the arc. Increasing the welding voltage hardly alters the current level, but lengthens the arc. By decreasing the voltage, a shorter arc is obtained with a little change in current level.

A satisfactory weld cannot be obtained if the Current (Wire Speed) and Voltage settings are not adjusted to suit the electrode wire diameter and the dimensions of the work piece.

If the Current (Wire Speed) is too high for the welding voltage, "stubbing" will occur as the wire dips into the molten pool and does not melt. Welding in these conditions normally produces a poor weld due to lack of fusion. If, however, the welding voltage is too high, large drops will form on the end of the wire, causing spatter. The correct setting of voltage and Current (Wire Speed) can be seen in the shape of the weld deposit and heard by a smooth regular arc sound.

Electrode Wire Size Selection The choice of Electrode wire size and shielding gas used depends on the following:

· Thickness of the metal to be welded · Type of joint

· Capacity of the wire feed unit and power source

· The amount of penetration required

· The deposition rate required

· The bead

desired

· The position of welding

· Cost of the wire

electrode wire needs more Current (Wire Speed) to achieve the same current level.

MIG Welding Troubleshooting
The general approach to Gas Metal Arc Welding (GMAW) problems is to start at the wire spool then work through to the MIG torch. There are two main areas where problems occur with GMAW, Porosity and Inconsistent wire feed.

When there is a gas problem the result is usually porosity within the weld metal. Porosity always stems from some contaminant within the molten weld pool which is in the process of escaping during so-
Contaminants range from no gas around the welding arc to dirt on the workpiece surface. Porosity can be reduced by checking the following points.

WARNING! Wire feeding problems can be reduced by checking the following points.

Other weld problems can be reduced by checking the following points.

MMA (Stick) Basic Welding Guide
Size of Electrodes
The electrode size is determined by the thickness of metals being joined and can also be governed by the type of welding machine available. Small welding machines will only provide current (amperage) to run smaller sized electrodes.
For thin sections, it is necessary to use smaller electrodes otherwise the arc may burn holes through the job. A little practice will soon establish the most suitableelectrode for a given application.
Storage of Electrodes
Always store electrodes in a dry place and in their original containers.
Electrode Polarity
Electrodes are generally connected to the electrode holder with the electrode holder connected positive polarity. The work lead is connected to the negative polarity and is connected to the work piece. If in doubt consult the electrode data sheet.

Various Materials
High Tensile and Alloy Steels
steels are the formation of a hardened zone in the weld area, and, if suitable precautions are not taken, the occurrence in this zone of under-bead cracks. Hardened zone and underbead cracks in the weld area may be reduced by using the correct electrodes, preheating, using higher current settings, using larger electrodes sizes, short runs for larger electrode deposits or tempering in a furnace.
Manganese Steels
high temperatures causes embrittlement. For this reason it is absolutely essential to keep manganese steelcool during welding by quenching after each weld or skip welding to distribute the heat.
Cast Iron Most types of cast iron, except white iron, are weldable. White iron, because of its extreme brittleness,

generally cracks when attempts are made to weld it. Trouble may also be experienced when welding white-heart malleable, due to the porosity caused by gas held in this type of iron.
Copper and Alloys The most important factor is the high rate of heat conductivity of copper, making pre-heating of heavy sections necessary to give proper fusion of weld and base metal.
Types of Electrodes
of groups depending on their applications. There are a great number of electrodes used for specialised industrial purposes which are not of particular interest for everyday general work. These include some low hydrogen types for high tensile steel, cellulose types for welding large diameter pipes, etc. The range of electrodes dealt with in this publication will cover the vast majority of applications likely to be encountered; are all easy to use.

tions without any special preparation. For heavier sections and for repair work on castings, etc., it will be necessary to cut or grind an angle between the pieces being joined to ensure proper penetration of the weld metal and to produce sound joints. In general, surfaces being welded should be clean and free of rust, scale, dirt, grease, etc. Slag should be removed from oxy-cut surfaces. Typical joint designs are shown in Figure 1-19.

Place yourself in a comfortable position before beginning to weld. Get a seat of suitable height and do as much work as possible sitting down. Don't hold your body tense. A taut attitude of mind and a tensed body will soon make you feel tired. Relax
You can add much to your peace of mind by wearing a leather apron and gauntlets. You won't be worrying then about being burnt or sparks setting alight to your clothes.
Place the work so that the direction of welding is across, rather than to or from, your body. The electrode holder lead should be clear of any obstruction so that you can move your arm freely along as the electrode burns down. If the lead is slung over your shoulder, it allows greater freedom of movement and takes a lot of weight your hand. Be sure the insulation on your cable and electrode holder is not faulty; otherwise you are risking an electric shock.

due to the tip of the electrode "stick-

ing" to the work piece. This is caused by making too

heavy a contact with the work and failing to with-

draw the electrode quickly enough. A low amper-

age will accentuate it. This freezing-on of the tip may

be overcome by scratching the electrode along the

plate surface in the same way as a match is struck. As

Arc Length
The securing of an arc length necessary to produce a neat weld soon becomes almost automatic. You will
A very long arc produces a crackling or spluttering noise and the weld metal comes across in large, ir-
increases. A short arc is essential if a high quality weld is to be obtained although if it is too short there is the danger of it being blanketed by slag and the elec-
give the electrode a quick twist back over the weld to detach it. Contact or "touch-weld" electrodes such as E7014 Stick electrodes do not stick in this way, and make welding much easier.
Rate of Travel
After the arc is struck, your next concern is to maintain it, and this requires moving the electrode tip towards the molten pool at the same rate as it is melting away. At the same time, the electrode has to move along the plate to form a bead.
The electrode is directed at the weld pool at about 20º from the vertical. The rate of travel has to be adjusted so that a well-formed bead is produced.
If the travel is too fast, the bead will be narrow and strung out and may even be broken up into individual globules. If the travel is too slow, the weld metal piles up and the bead will be too large.

Making Welded Joints
Having attained some skill in the handling of an electrode, you will be ready to go on to make up welded joints.
A. Butt Welds
Set up two plates with their edges parallel, as shown in Figure 1-21, allowing 1.6mm to 2.4mm gap between them and tack weld at both ends. This is to prevent contraction stresses from the cooling weld metal pulling the plates out of alignment.
Plates thicker than 6.0mm should have their mating edges bevelled to form a 70º to 90º included angle. This allows full penetration of the weld metal to the root. Using a 3.2mm E7014 Stick electrode at 100 amps, deposit a run of weld metal on the bottom of the joint.
Do not weave the electrode, but maintain a steady

for undercut to form, but keeping the arc length short, the angle of the electrode at about 20º from vertical, and the rate of travel not too fast, will help eliminate this.
The electrode needs to be moved along fast enough to prevent the slag pool from getting ahead of the arc. To complete the joint in thin plate, turn the job over, clean the slag out of the back and deposit a similar weld.

Heavy plate will require several runs to complete the
and clean the weld with a wire brush. It is important to do this to prevent slag being trapped by the second run. Subsequent runs are then deposited using either a weave technique or single beads laid down in the sequence shown in Figure 1-22. The width of weave should not be more than three times the core wire diameter of the electrode.

machined, ground or gouged out to remove slag which may be trapped in the root, and to prepare a suitable joint for depositing the backing run. If a backing bar is used, it is not usually necessary to remove this, since it serves a similar purpose to the backing run in securing proper fusion at the root of the weld.

B. Fillet Welds
These are welds of approximately triangular crosssection made by depositing metal in the corner of two faces meeting at right angles. Refer to Figure 1-14, 1-23 and 1-24.

45o from vertical
60o-70o from line of weld

A piece of angle iron is a suitable specimen with which to begin, or two lengths of strip steel may be tacked together at right angles. Using a 3.2mm E7014 Stick electrode at 100 amps, position angle iron with one leg horizontal and the other vertical. This is known as a horizontal-vertical (HV)
Strike the arc and immediately bring the electrode to
about 45º from the vertical. Some electrodes require being sloped about 20º away from the perpendicular position to prevent slag from running ahead of the weld. Refer to Figure 1-23.
Do not attempt to build up much larger than 6.4mm width with a 3.2mm electrode, otherwise the weld metal tends to sag towards the base, and undercut forms on the vertical leg. Multi-runs can be made as shown in Figure 1-24. Weaving in HV welds is undesirable.

Multi-Runs in HV Fillet Weld (Fig 1-24)
C. Vertical Welds
1. Vertical Up Tack weld a three feet length of angle iron to your work bench in an upright position. Use a 3.2mm E7014 Stick electrode and set the current at 100 amps. Make yourself comfortable on a seat in front of electrode needs to be about 10º from the horizontal to enable a good bead to be deposited. Refer Fig. 1-25.
Single Run Vertical Fillet Weld (Fig 1-25)
Use a short arc, and do not attempt to weave on the slag the weld deposit and begin the second run at the bottom. This time a slight weaving motion is necat the edges.
Multi Run Vertical Fillet Weld (Fig 1-26)
Weaving motion for second and subsequent runs
Pause at edge of weave
At the completion of each side motion, pause for a moment to allow weld metal to build up at the edges, otherwise undercut will form and too much metal will accumulate in the centre of the weld. Figure 1-26 illustrates multi-run technique and Figure 1-27 and of weaving too rapidly.

2. Vertical Down
The E7014 Stick electrode makes welding in this position particularly easy. Use a 3.2mm electrode at 100 amps. The tip of the electrode is held in light contact with the work and the speed of downward travel is regulated so that the tip of the electrode just keeps ahead of the slag. The electrode should point upwards at an angle of about 45º.

The electrode is held at 45º to the horizontal and tilted 10º in the line of travel (Figure 1-28). The tip of the electrode may be touched lightly on the metal, which helps to give a steady run. A weave technique

TIG Basic Welding Guide

electrode since 70% of the heat is concentrated at the work piece.

TIG Welding is a fusion procedure that uses an electric ARC created between an infusible tungsten electrode and base material to be welded. For TIG welding an inert gas must be used (Argon) which protects
up of rods suitable to the material to be welded (steel, stainless steel, copper etc).

In TIG mode, welding is possible in all positions: angle, on the edge, vertical and overhead. Furthermore, with respect to other types of welding, the welding joint has greater mechanical resistance, greater corrosion resistance and limited heating in the welded area which limits distortion. Welding can be done even without weld material, guaranteeing a smooth, shiny weld with no impurities or slag.
