WARNING
Read and understand the instruction manual before installing or operating.
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
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.
NOISE - Excessive noise can damage hearing
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!
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.
CAUTION
This product is solely intended for plasma cutting.
CAUTION
Read and understand the instruction manual before
installing or operating.

Duty cycle
The duty cycle refers to the time as a percentage of a ten-minute period that you can weld or cut at
a certain load without overloading. The duty cycle is valid for 40°C.
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.
4 INSTALLATION
The installation must be carried out by a professional.
Correct installation is very important for trouble-free operation and good cutting
results. Carefully read and follow each step in this chapter.
WARNING
ELECTRIC SHOCKS CAN KILL Take precautionary measures against electric
shocks. Ensure that all power supplies are disconnected –switch off the switch
at the wall socket and pull out the equipment's power cable from the socket before
making any electrical connections in the power source.
WARNING
It is very important that the chassis is connected to the approved electric protective
earth, to prevent electric shocks and electrical accidents. Ensure that protective
earth is not connected to any phase conductors by mistake.
WARNING
Poor connections or failure to connect the return cable to the workpiece can result
in fatal electric shock.
WARNING
Air filter devices may not be used –installation or mounting of any form of air
filter device obstructs the cold air flow and causes a risk of overheating.
The warranty is invalidated if any type of air filter is used.

WARNING
Do NOT start the equipment with the cover removed.
Do NOT connect the power source with the main switch in ON position
or when you are holding it or carrying it.
Do NOT touch any of the torch's parts when the power supply is on.
CAUTION
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.
CAUTION
Place the power source at least 3 metres from the cutting area as sparks and slag spray
can damage the power source
4.1 Delivery check and location
1. Remove the packaging. Inspect the equipment for damage that was not
immediately apparent upon reception of the delivery. Immediately report any
damage to the delivery company.
2. Check for any loose parts in the packaging. Check that the air ducts in the
cover's rear panel are not blocked by packaging material that can prevent the air
flow through the power source.
The power source has a carrying handle and can be lifted easily.
3. Position the power source so that its cooling air inlets and outlets are not
obstructed. Minimum permitted distance to wall or other obstruction is 1 m.
4. An air source that gives clean and dry air, at least 189 l/m at 4.8 bar, is
required for cutting. The cutting air pressure must not exceed 6 bar, which is the
maximum inlet pressure for the filter regulator that is included in the delivery.
