INITIAL OPERATING
Mains connection:
Input voltage should be as stated on the type plate of the machine. If dual voltage, the tapping must be checked
before mains connection.
Shielding gas connection:
The shielding gas bottle is mounted on the machine and the regulator on the bottle. If the regulator is equipped
with flowmeter, the gas quantity is adjusted on 5-15 litres/min.
Welding hose connection:
The welding hose is put through the hole in the front plate and into the switch on the wire feed console (see page
11). Keep the inlet nozzle as close to the wire feed roller as possible without letting them touch each other.
Fasten the Allen screw and mount the gas hose and the control wire. Check that the hole in the inlet nozzle is in
line with the groove of the wire feed roller.
Fitting the welding wire:
Turn the tension spring aside and tip it up. Check that the wire feed roller, the wire guide liner and the contact tip
correspond to the wire diameter, the wire feed roller is designed for two wire dimensions and should be turned
around until the outer side is showing the wire size being used. The following wire guide liner is recommended

When using aluminium wire use a special guide liner where the internal liner goes all the way through the inlet
nozzle. This prevents the aluminium wire from being damaged.
The reel of wire is put on the hub, and the wire is put through the wire feed unit and some centimeters into the
hose. As the wire guide liner is vulnerable to burrs at the point of the wire, it is important to file the point of the
wire in order to remove all burrs and it is equally important to straighten out the first 10-15 cm. Unscrew contact
nozzle. Tip up the lever. Set the wire speed at 6, press the start button, the wire runs through the hose. When
the wire is through the hose, stop the machine and mount the contact nozzle. The pressure of the lever is
adjusted to allow the wire feed roller just to slide on the wire when this is stopped at the
contact nozzle.

The special welding hose is mounted at the quick clutch of the machine and the Jack-sleeve and the welding
handle is mounted with the desired electrode holder.
For planishing of dents with carbon the voltage switch of the machine shall be set at step 8 whereas voltage step
7 is used when welding nails or discs. Using this method it is important for a satisfactory result that you do not
press the handle too hard against the workpiece as the contact resistance between nail (discs) and the piece is
reduced and the desired generation of heat is decreased.
You must also take care that the return clip is in good contact with the piece and is not attached too far from the
welding point.
