*) The minimum current during AC welding depends on the alloy used for the aluminium plates and
their surface cleanliness.
Duty cycle
The duty cycle refers to the time as a percentage of a ten--minute period that you can weld at a cer-
tain load without overloading.
The duty cycle is valid for 40˚C ambient temperature.
Enclosure class
The IP code indicates the enclosure class, i. e. the degree of protection against penetration by solid
objects or water. Equipment marked IP23 is designed for indoor and outdoor use.
Application class
The symbol indicates that the power source is designed for use in areas with increased
electrical hazard.
5 INSTALLATION
The installation must be executed by a professional.
WARNING!
This product is intended for industrial use. In a domestic environment this product may cause radio
interference. It is the user’s responsibility to take adequate precautions.

6.2 Key to symbols
MMA TIG Return clamp
6.3 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.
6.4 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.
6.5 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 panel.
They reset automatically when the temperature has fallen.
6.6 Cooling unit
Water lock
The cooling unit is equipped with a detection system ELP (ESAB Logic Pump) which
checks that the water hoses are connected.
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 page 17.
7 MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Only those persons who have appropriate electrical knowledge (authorized
personnel) may remove the safety plates to connect or carry out service,
maintenance or repair work on welding equipment.
Note!
All guarantee undertakings from the supplier cease to apply if the customer himself
attempts any work in the product during the guarantee period in order to rectify any
faults.
7.1 Cleaning the air filter
SRelease the cover plate with the dust
filter (1).
SSwing out the cover plate (2).
SRemove the dust filter (3).
SBlow it clean with compressed air at
reduced pressure
SReplace the filter with the finer mesh
on the side against the cover plate (2)
SRefit the cover plate with the filter.
7.2 Topping up the coolant
Top up with coolant until it is up to the level of the filling hole.
ESAB’s refrigerant is recommended for use.
See accessories on page 17.
CAUTION!
The coolant must be handled as chemical waste.
