Important!
In order to avoid destruction of plugs
and cables, good electric contact
is required when connecting earth
cables and welding hoses to the
machine.
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 (0-8 bar). (Note: Some types of pressure
regulators require an output pressure of more than 2 bar
to function optimally).
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.
Adjustment:
•
Adjust the wire brake by fastening or loosening the
self-locking nut on the axle of the wire hub.
Inching
This function is for wire inching/
feeding, e.g. after change of wire.
To feed the wire, press and hold
down the key while triggering the
torch trigger.

The welding voltage indicator is illuminated for
reasons of safety and in order to show if there is
voltage at the torch.
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.
Change of polarity:
1. Disconnect the machine from the
mains supply.
2. Dismount the milled nuts at the
poles (fig. 1).
3. Reverse the cables (fig. 1).
4. Mount the milled nuts (fig. 1).
5. Exchange earth cable from minus
to plus (fig. 2).
6. Connect the machine to the mains
supply.
