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
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. Use a wrench to dismount the bolts and discs at
the poles.
3. Reverse the cables.
4. Use a wrench to mount the bolts and discs.
5. Connect the machine to the mains supply.
