WARNING
Arc welding and cutting can be injurious to yourself and others. Take precautions when welding and
cutting. Ask for your employer's safety practices which should be based on manufacturers' hazard
data.
ELECTRIC SHOCK - Can kill
Install and earth the unit in accordance with applicable standards.
Do not touch live electrical parts or electrodes with bare skin, wet gloves or wet clothing.
Insulate yourself from earth and the workpiece.
Ensure your working stance is safe.
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.
FIRE HAZARD
Sparks (spatter) can cause fire. Make sure therefore that there are no inflammable materials nearby.
NOISE - Excessive noise can damage hearing
Protect your ears. Use earmuffs or other hearing protection.
Warn bystanders of the risk.
MALFUNCTION - Call for expert assistance in the event of malfunction.
Read and understand the instruction manual before installing or operating.
PROTECT YOURSELF AND OTHERS!
WARNING
Do not use the power source for thawing frozen pipes.
CAUTION
Read and understand the instruction manual before
installing or operating.
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.

INSTALLATION
The installation must be carried out by a professional.
4.1 Location
Place the power source so that its cooling air inlets and outlets are not obstructed.
4.2 Mains supply
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
distribution network operator if necessary, that the equipment may be connected.
4.3 Mains power supply
Make sure that the welding power source is connected to the correct supply voltage
and that it is protected by the correct fuse rating. A protective earth connection must
be made in accordance with regulations.

5.2 Connection of welding and return cable
The power source has two outputs, a positive terminal (+) and a negative terminal
(-), for connecting welding and return cables. The output to which the welding cable
is connected depends on the type of electrode used. The connecting polarity is
stated on the electrode packaging.
Connect the return cable to the other output on the power source. Secure the return
cable's contact clamp to the work piece and ensure that there is good contact
between the work piece and the output for the return cable on the power source.

5.3 TIG welding
At TIG-welding complete the power source with:
a TIG torch with gas valve
an argon gas tube
an argon gas regulator
tungsten electrode
5.4 Overheating protection
The welding power source has overheating protection that operates if the
temperature becomes too high. When this occurs the welding current is interrupted
and a fault code is displayed on the control panel.
The overheating protection resets automatically when the temperature has fallen.
6
MAINTENANCE
Regular maintenance is important for safe, reliable operation.
Only those persons who have appropriate electrical knowledge (authorized
personnel) may remove the safety plates.
CAUTION
All guarantee undertakings from the supplier cease to apply if the customer attempts any
work to rectify any faults in the product during the guarantee period.
6.1 Power source
Check regularly that the welding power source is not clogged with dirt.
How often and which cleaning methods apply depend on:
the welding process
arc times
placement
the surrounding environment.
It is normally sufficient to blow the power source clean with dry compressed air
(reduced pressure) once a year.
Clogged or blocked air inlets and outlets otherwise result in overheating.
6.2 Welding torch
The wear parts should be cleaned and replaced at regular intervals in order to
achieve trouble-free welding.

FAULT-TRACING
Try these recommended checks and inspections before sending for an authorized
service technician.
Type of fault
Corrective action
No arc.
Check that the mains power supply switch is turned on.
Check that the welding current supply and return cables are
correctly connected.
Check that the correct current value is set.
Check the mains power supply fuses.
The welding current is
interrupted during welding.
Check whether the thermal cut-outs have tripped (a fault
code is displayed on the control panel).
Check the mains power supply fuses.
The thermal cut-out trips
frequently.
Make sure that you are not exceeding the rated data for the
welding power source (i.e. that the unit is not being
overloaded).
Check that the welding power source is not clogged with dirt.
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 electrodes are being used.
