1 SAFETY
4. Personal safety equipment:  Always wear recommended personal safety equipment, such as safety glasses, flame-proof clothing, safety gloves  Do not wear loose-fitting items, such as scarves, bracelets, rings, etc., which could become trapped or cause burns
5. General precautions:  Make sure the return cable is connected securely  Work on high voltage equipment may only be carried out by a qualified electrician  Appropriate fire extinguishing equipment must be clearly marked and close at hand  Lubrication and maintenance must not be carried out on the equipment during operation
WARNING! Arc welding and cutting can be injurious to yourself and others. Take precautions when welding and cutting.
ELECTRIC SHOCK - Can kill
· Install and ground the unit in accordance with instruction manual. · Do not touch live electrical parts or electrodes with bare skin, wet gloves or
wet clothing. · Insulate yourself from work and ground. · Ensure your working position is safe
ELECTRIC AND MAGNETIC FIELDS - Can be dangerous to health
· Welders having pacemakers should consult their physician before welding. EMF may interfere with some pacemakers.
· Exposure to EMF may have other health effects which are unknown. · Welders should use the following procedures to minimize exposure to
EMF:  Route the electrode and work cables together on the same side of
your body. Secure them with tape when possible. Do not place your body between the torch and work cables. Never coil the torch or work cable around your body. Keep welding power source and cables as far away from your body as possible.  Connect the work cable to the workpiece as close as possible to the area being welded.
FUMES AND GASES - Can be dangerous to health
· Keep your head out of the fumes. · Use ventilation, extraction at the arc, or both, to take fumes and gases
away from your breathing zone and the general area.
ARC RAYS - Can injure eyes and burn skin
· Protect your eyes and body. Use the correct welding screen and filter lens and wear protective clothing.
· Protect bystanders with suitable screens or curtains.
NOISE - Excessive noise can damage hearing
Protect your ears. Use earmuffs or other hearing protection.

1 SAFETY
MOVING PARTS - Can cause injuries · Keep all doors, panels and covers closed and securely in place. Have only
qualified people remove covers for maintenance and troubleshooting as necessary. Reinstall panels or covers and close doors when service is finished and before starting engine. · Stop engine before installing or connecting unit. · Keep hands, hair, loose clothing and tools away from moving parts.
FIRE HAZARD · Sparks (spatter) can cause fire. Make sure that there are no inflammable
materials nearby. · Do not use on closed containers. MALFUNCTION - Call for expert assistance in the event of malfunction. PROTECT YOURSELF AND OTHERS!
CAUTION! This product is solely intended for arc welding.
WARNING! Do not use the power source for thawing frozen pipes.
CAUTION! Class A equipment is not intended for use in residential locations where the electrical power is provided by the public low-voltage supply system. There may be potential difficulties in ensuring electromagnetic compatibility of class A equipment in those locations, due to conducted as well as radiated disturbances.
NOTE! Dispose of electronic equipment at the recycling facility! In observance of European Directive 2012/19/EC on Waste Electrical and Electronic Equipment and its implementation in accordance with national law, electrical and/or electronic equipment that has reached the end of its life must be disposed of at a recycling facility. As the person responsible for the equipment, it is your responsibility to obtain information on approved collection stations. For further information contact the nearest ESAB dealer.
ESAB has an assortment of welding accessories and personal protection equipment for purchase. For ordering information contact your local ESAB dealer or visit us on our website.

2 INTRODUCTION

2

INTRODUCTION

TAF 801 is a remote-controlled, two-phase AC welding power source designed for high-throughput, mechanised submerged-arc welding (SAW).
The welding power source converts, via a thyristor bridge-rectifier, the secondary voltage's sine wave to a square wave with excellent arc ignition and welding characteristics.
The welding power source is fan cooled and is overload protected by a thermal cut-out. Re-setting takes place automatically as soon as the temperature has reduced to a permitted level.

INSTALLATION

The installation must be carried out by a professional.

NOTE!
Mains supply requirements
High power equipment may, due to the primary current drawn from the mains supply, influence the power quality of the grid. Therefore connection restrictions or requirements regarding the maximum permissible mains impedance or the required minimum supply capacity at the interface point to the public grid may apply for some types of equipment (see "TECHNICAL DATA" chapter). In this case it is the responsibility of the installer or user of the equipment to ensure, by consultation with the distrubution network operator if necessary, that the equipment may be connected.

4.1 Location
WARNING! Secure the equipment - particularly if the ground is uneven or sloping.

· Place the welding power source on a level foundation. · Make sure there is nothing to prevent the cooling.

4.2 Connections

· On delivery the welding power source is connected for

400 V. For other supply voltage, switch over to the

desired voltage on the main transformer and the

control transformer according to the connection

instructions in "CONNECTION INSTRUCTION"

chapter.

· Make sure the mains cable has the right sectional

area and fuse it with an adequate fuse according to

applicable local directions (see table below in "Mains

connection" section).

· Connect the earth cable to the screw marked .

· Connect the mains cable to the main terminal blocks

L1 and L3.

· Tighten the cable support (1 ).

· Connect the control cable between the welding power

source and the control unit to the 28-pole contact (2 )

inside the welding power source.
