1 Safety precautions

Use and maintenance of welding and cutting
machines can be dangerous. Please draw
user´s attention to follow the safety precau-
tions to avoid injuries. Welding and cutting
machines must be used appropriate and
only by specialist staff. Please inform your-
self constantly about the valid safety pre-
cautions and regulations of accident pre-
vention by working with this machine*.
Remove all flammable material from the weld-
ing area for fire prevention before welding.
Do not weld at containers which were filled up
before with flammable materials (fuel).
All inflammable material in the welding area
which could be inflamed by sparks must be re-
moved.
Check after welding the place conforming UVV.
Do not expose the unit to rain, steam and do not
spray water in it.
Do not weld without protection shield. Keep at-
tention to protect other persons in the welding
area against arc-rays.
Please use absorbers or other systems to ab-
sorb the gases.
It is not possible to absorb all the gases correct-
ly please use a breathing apparatus.
Stop operation immediately at a defect or
damaging of the mains cable. Do not touch
the cable. Unplug the unit before each serv-
ice or repair. Do not use the machine if the
mainscable is defect.
Place an extinguisher near the welding area.
Check the welding area against fire after weld-
ing.
Never try to repair a defect pressure reducer.
Replace the defect one.
Keep attention to connect the ground cable near the weld-
ing location. Welding current through chains, ball-bearing
or steel-cables may destruct or melt it.
Lock the brake on the transport rollers 10 when the ma-
chine is at the welding site.
Secure yourself and the unit at higher or inclinational plac-
es.
Connect the unit only at mains with correct connection to
ground / earth and at prolongations and sockets too.
Wear correct protective clothing, gloves and leather apron.
Protect the welding area with curtains or mobile walls
against rays.
Do not thaw frozen waterpipes or conductions with this
unit.
In high electrical risk areas (in confined spaces) it is only
allowed to use machines with

S -sign.
Secure the gas cylinder with a chain against falling over.
Please take off the gas cylinder from the machine for trans-
portation.
Disconnect the plug from the mains before changing the
welding area or repairs at the machine.

3 General regulation of use

This unit is for welding steel, aluminium and their alloys, for
commercial as well as for industrial use.

4 Unit protection

This unit is protected electronically against overloading.
Close the side lid before welding.
Connect the workpiece with the groundcable to the unit.
Remove welding spatter from the inside of the gas nozzle with
a special pair of pliers. Spray with anti spatter spray inside the
gas nozzle to avoid adherence of spatters. Spray sloping to
avoid the obstruction of the gasoutlet.
At transportation of the unit only use the purposed transpor-
tation facilities 5, do not use a fork-lift truck or something sim-
ilar at the machine case.
