Adjustment of wire brake
The wire brake must ensure that the wire reel brakes
sufficiently quickly when welding stops. The required
brake force is depending on the weight of the wire reel
and the maximum wire feed speed. A brake torque of 1.5-
2.0 Nm will be satisfactory for most applications.
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 knob by
pressing it back into the
groove.
Selection of welding polarity
We recommend that you shift welding polarity for certain
types of welding wire, and this especially as regards Inner
shield welding wire. Please control the recommended
polarity stated on the packing of the welding wire.

1. Place the welding machine on top of the cooling
unit and mount the fitting (1).
2. Pull the power cable (2) through the hole on the
rear side of the machine. Dismount the
protection fitting (3) in the wire chamber and
insert the 4-pole plug (4). Remount the
protection fitting.
3. Dismount the two screws (5) on the fitting with
the quick connections (6).
4. Pull out and turn the fitting so that the quick
connections turn up. Then remount the fitting
with the screws (5) (see drawing).
5. Mount the flow hose on the water-cooled torch in
the quick connection marked blue and the return
hose in the quick connection marked red.
6. The cooling liquid level should be inspected
regularly by means of the level control (7).
7. Refill of cooling liquid takes place through the
filler neck (8).
