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 yourself constantly about the valid safety precautions and regulations of accident prevention by working with this machine*.
Remove all flammable material from the welding 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 attention to protect other persons in the welding
area against arc-rays.
Please use absorbers or other systems to absorb the gases.
It is not possible to absorb all the gases correctly 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
-sign.
Switch off the machine at breaks and close the valve of the
gas cylinder.
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.
*) Please follow the current safety regulations corresponding
to your country.

This unit is for welding steel, aluminium and their alloys, for
commercial as well as for industrial use.
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 transportation facilities 5, do not use a fork-lift truck or something similar at the machine case.

The sound level of the unit is smaller as 70 dB (A) measured
at standard load conforming EN 60
974 at the max. work-
point.
Depending on the operation, users of commercially operated
welding systems are obliged to have safety inspections of the
equipment carried out regularly in accordance with
VDE
0544-207. ELEKTRON recommends inspection periods
of 12 months.
A safety inspection must also be carried out after alterations
or repair of the system.
! Caution ! : Improperly carried out UVV inspections can destroy the system.
For more information on UVV inspections of welding systems,
please contact your authorized service center.
This product is manufactured conform to the current EMV
standard. Please notice following items:
The unit is for welding under commercial or industrial con-
ditions. The use in other surroundings (for example in residential areas) may disturb other electric devices.
During welding electromagnetic problems can be caused
at:
– Mainscables, controlcables, connections for telecom-
munication
–TV / Radio
– Computer and other similar devices
– Protection devises as for example alarm systems
– Pacemakers and hearing aids
– Devices for measure and calibrate
– Devices with less protection against disturbances
If other devices are disturbed it may be necessary to pro-
tect additionally.
The affected area can be bigger than your premises /
property depends of the building etc.
Please use the unit conform to the instructions of the manufacturer. The user is responsible for installation and use of the
machine. Furthermore the user is responsible to eliminate the
disturbances caused by electromagnetic fields.

Place gas cylinder 3 on machine and secure with safety
chain 35.
Remove screw cap from gas cylinder and open gas cylin-
der valve 34 briefly (blow-off).
Connect pressure reducer 2 to gas cylinder.
Connect gas hose 31 from machine to pressure reducer
and open gas cylinder.
Plug mains plug in socket.
Connect ground cable 22 to ground connection 14 (–) and
attach ground clamp 13 to workpiece.
Insert wire feed roller 29 to wire feeder to fit welding wire
selected, set contact pressure to position 2.

red-blue) and mount contact tip to fit welding wire selected.
Insert welding wire.
Turn on main switch 11.
Press push-button 51 and push-button 48 (gas type)
(solenoid valve is activated) and adjust gas amount on the
pressure reducer
(rule of thumb: wire diameter x 10 = gas flow).

Torch connection
Plug in the centralplug 17 of the torch 1 into the central socket
16. At machines with water-cooling: Connect additionally the
waterconnections 20 of the torch with the sockets 18 and 19.
Please keep attention at the colour labelling.
Red = water back-run 19
Blue = water fore-run 18
How to connect the ground cable
Connect the ground cable 22 at the groundconnection 14 and
fasten it turning to right and connect the ground clamp 13 to
the workpiece or at the welding table.
How to connect the ground clamp
Fasten the ground clamp 13 near the welding location, this
avoids that the current will flow trough machineparts or con
-
trols.
Please keep attention that the connections between ground
clamp and workpiece is constant.
Do not place the ground clamp on the welding machine or
gas cylinder, otherwise welding current is conducted via
the protective conductors and will destroy them.
Connect the ground clamp tightly to the welding bench or
to the workpiece.
How to connect at the mains
Plug in the plug into the mains socket. The fusing should be
corresponding to the technical data.
How to insert the wirespool
Open the lid at the machine or at the wire-feed case 2 and
screw off the nut 26 from the wire-coil pick-up 24.
Put on the wire coil at the wire-coil pick-up and pay attention
that the tappet is well insert at the coil 23.
By use of small wire coils please use the adapter.
Adjust the brake 25 by releasing the torch button the wire coil
do not continue to turn.
Insert of the wire electrode
Screw out the contact tip at the torch 1.
Open the lid at the unit or at the wire feeder 2.
The diameter of the wire should correspond to the diameter of
the feeding rolls. This is readable on the front at the built in
feeding roll 29.
Lift the lever 27 and thread in the wire electrode trough the inlet nozzle 28 and the central connection 16.
Close the lever 30 and fasten it with the sweep levers 27.
Switch on machine at main switch 11, stretch torch cable and
press button wire insert
on operating panel. Adjust the
pressure at the modulation screws 27 that the wire-feed rolls
29 even still are turning by holding the wire coil. The wire
should not be clamped or deformed.
