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
0460 157 301 -6- © ESAB AB 2018

5 OPERATION
0460 157 301 - 13 - © ESAB AB 2018
5.2 Key to symbols
MMA TIG Return clamp
5.3 Turning on the power source
Turn on the mains power by turning switch (9) to the "START" position. Release the switch,
and it will return to the "1" position.
If the mains power supply should be interrupted while welding is in progress, and then be
restored, the power source will remain de-energised until the switch is again turned manually
to the "START" position.
Turn the unit off by turning the switch to the "0" position
Whether in the event of a loss of power supply or of turning the power source off in the
normal manner, welding data will be stored so that it is available next time the unit is started.
5.4 Fan control
The power source fans continue to run for 6.5 minutes after welding has stopped, and the
unit switches to energy-saving mode. They start again when welding restarts.
The fans run at reduced speed for welding currents up to 144A, and at full speed for higher
currents.
5.5 Overheating protection
The power source has two thermal overload trips which operate if the internal temperature
becomes too high, interrupting the welding current and lighting the orange indicating lamp on
the front of the unit and a fault code is shown in the control panel. They reset automatically
when the temperature has fallen.
5.6 Cooling unit
Water lock
The cooling unit is equipped with a detection system ELP (ESAB Logic Pump) which checks
whether the water hoses are connected.

5 OPERATION
0460 157 301 - 14 - © ESAB AB 2018
The power source On/Off switch must be in the "0" position (Off) when connecting a
water-cooled TIG torch.
If a water-cooled TIG torch is connected, the water pump starts automatically when the main
On/Off switch is turned to "START" and/or when welding starts. After welding, the pump
continues to run for 6.5 minutes, and then switches to the energy-saving mode.
Function when welding
To start welding, the welder presses the torch trigger switch. The power source energises the
torch and starts wire feed and the cooling water pump.
To stop welding, the welder releases the torch trigger switch. The welding current is
interrupted, but the cooling water pump continues to run for 6.5 minutes, after which the unit
switches to energy-saving mode.
Water flow guard
The water flow guard interrupts the welding current in the event of loss of coolant, and
displays an error message on the control panel. The water flow guard is an accessory, see
"ACCESSORIES" chapter.

6 MAINTENANCE
0460 157 301 - 15 - © ESAB AB 2018
6 MAINTENANCE
NOTE!
Regular maintenance is important for safe and reliable operation.
Only those persons who have appropriate electrical knowledge (authorised personnel) may
remove the safety plates to connect or carry out service, maintenance or repair work on
welding equipment.
CAUTION!
All warranty undertakings from the supplier cease to apply if the customer attempts
any work to rectify any faults in the product during the warranty period.
6.1 Cleaning the filter
• Remove the front grille with the filter (1).
• Swing out the front grille (2).
• Remove the filter (3).
• Blow the filter clean with compressed air (reduced
pressure).
• Replace the filter with the finer mesh on the side
against the front grille (2).
• Replace the front grille with the filter.
6.2 Topping up the coolant
Top up with coolant until it is up to the level of the filling
hole.
ESAB ready mixed coolant is recommended for use, see
"ACCESSORIES" chapter.
NOTE!
Coolant must be topped up if connecting a
welding torch or connection cables that are 5m
(16.4ft) in length or longer.
CAUTION!
The coolant must be handled as chemical waste.

7 TROUBLESHOOTING

fault code is shown in the panel.
• Check the coolant flow.
• Check the main power supply fuses.
The thermal cut-out trips
operate frequently.
• Check to see whether the air filters are clogged.
• Make sure that you are not exceeding the rated data for
the power source (i.e. that the unit is not being
overloaded).
Poor welding performance • Check that the welding current supply and return cables
are correctly connected.
• Check that the correct current value is set.
• Check that the correct electrode / wire is used.
• Check that the correct welding gas is being used.
