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.
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.
