WARNING
Read and understand the instruction manual before installing or operating.
Arc welding and cutting can be injurious to yourself and others. Take precausions when welding and
cutting. Ask for your employer's safety practices which should be based on manufacturers' hazard
data.

SInstall and earth the unit in accordance with applicable standards.
SDo not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
SInsulate yourself from earth and the workpiece.
SEnsure your working stance is safe.
FUMES AND GASES - Can be dangerous to health
SKeep your head out of the fumes.
SUse 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.
SProtect your eyes and body. Use the correct welding screen and filter lens and wear protective
clothing.
SProtect bystanders with suitable screens or curtains.
FIRE HAZARD
SSparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.

SProtect your ears. Use earmuffs or other hearing protection.
SWarn bystanders of the risk.
MALFUNCTION - Call for expert assistance in the event of malfunction.
PROTECT YOURSELF AND OTHERS!
CAUTION
Read and understand the instruction manual before
installing or operating.
WARNING
Do not use the power source for thawing frozen pipes.
CAUTION
This product is solely intended for arc welding.
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
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). 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.

this model.
7Connection for start signal from the
welding torch
15 Connection for cooling water. Not used on
this model.
8Connection for gas to the TIG torch
5.2 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.
