Controls Explained
LCD Current & Voltage Display Meters
These indicate the actual voltage and current readings at the output terminals of the welding machine. The current meter should read ‘O’ except when welding is actually taking place. The voltage meter will indicate output voltage during welding and the welding open circuit voltage when the machine is powered up but not welding. In MIG mode the open circuit voltage will only appear once the torch is triggered to activate the circuit, in MMA and Lift TIG mode, the open circuit voltage will show on the display continuously. The digital meters are very sensitive and accurate, so it is not abnormal to observe some small fluctuations on them when the machine is at rest.
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 specific corresponding ‘sweet spot’ in the wire feeding speed that will give the smoothest and most stable welding arc. The correct wire feeding speed for a given voltage setting is affected by welding wire type 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 Of the wire feeder cover door and further on in this manual.
Power Supply
Electrical Connection
The WT180MP is designed to operate on a 10A 240V AC power supply.
Extension Leads
If an extension cord must be used, it should be minimum cable core size 2.0mm? for length of up to 10m, or minimum 2.5mm’ for length up to 20m. Using extension leads of over 20m is not recommended.
Generator Use
This machine has a wide input power variation tolerance (~170-265V), allowing it to operate off generator power. However, this machine is NOT designed for frequent generator use and is NOT protected against poor quality power or voltage spikes. Any damage caused by generator power supply is not covered under warranty.
If generator power must be used, generator size should be not less than 8kva. Avoid using poor, low quality generators as these have the greatest risk of power spikes etc. A suitable quality generator should have a THD (total harmonic distortion) rating of not more than 6%. Most reputable generator supplier will be able to specify the THD ratings on their product.

Wire Jam Troubleshooting
• If wire jam occurs when the torch becomes hot, this is often because the heat causes the wire and the tip to expand (which shrinks the hole in the tip). Using a slightly oversize tip can prevent this – eg: for 0.9mm wire, use a 1.0mm tip.
• Do NOT over-tighten the drive roll tension – this will accelerate wear of the drive system, may distort the wire & will cause further wire feed problems.
Care & Maintenance
Keep your Welding Machine in Top Condition
The WT180MP does not require any special maintenance, however the user should take care of the machine as follows:
• Regularly clean the ventilation slots.
• Keep the casing clean.
• Check all cables before use.
• Check electrode holders, work lead/clamps and welding torches before use.
• Replace worn electrode holders and earth clamps, which do not provide a good connection.
• Replace worn torch consumable parts in a timely manner.
• Replace worn wire drive components in a timely manner.
• Use a soft cloth or brush to clean electrical components. Do not use liquid cleaning products, water or especially solvents.
• Do not use compressed air to clean electrical components as this can force dirt and dust further into components, causing electrical short circuits.
• Check for damaged parts.
If damaged, before further use, the welder must be carefully checked by a qualified person to determine that it will operate properly. Check for breakage of parts, mountings and other conditions that may affect its operation.
Have your welder repaired by an expert. An authorised service centre should properly repair a damaged part.
This appliance is manufactured in accordance with relevant safety standards. Only experts must carry out repairing of electrical appliances, otherwise considerable danger for the user may result.
Use only genuine replacement parts. Do not use modified or non-genuine parts.
