Connection and operation
Adjustment of wire brake
The wire brake must ensure that the wire reel brakes
sufficiently before the welding wire runs over the edge of
the reel. The brake force is dependent on the weight of
the wire reel and wire feed speed.
Factory setting is 15kg.
Adjustment:
• Dismount the control
knob by placing a thin
screw driver behind the
knob and thereafter pull
it out.
• Adjust the wire brake by
fastening or loosening
the self-locking nut on
the axle of the wire hub.
• Remount the control knob.
Connection of shielding gas
Connect the gas hose, which branches off from the back
panel of the welding machine (3), to a gas supply with
pressure regulator (2-6 bar). (Note: Some types of pressure
regulators require an output pressure of more than 2 bar
to function optimally).
One/two gas cylinders can be mounted on the bottle
carrier on the back of the trolley.

Torch adjustment (Dialog torch)
The welding current, wire feed speed or thickness of
material can be adjusted both from the machine and the
welding torch if a welding hose with dialog torch is in
use. The torch adjustment is passive without Dialog torch.
Inching AUTOMIG
The function is used for wire
inching e.g. after change of wire.

Wire inching starts by pressing the
green key pad and simultaneously
triggering the torch trigger. Wire
inching continues even though the
green key pad has been released. It
does not stop until the torch trigger
has been released again.
Selecting
welding polarity
Polarity reversal is recommended for
certain types of welding wire, in particular
Innershield welding wire. For recommended
polarity, please refer to the welding wire
packaging.
Please note:
