Connection and operation
Connection of electrode holder for MMA
The electrode holder and earth cable are
connected to plus connection (10) and minus
connection (8). Observe the instructions from the
electrode supplier when selecting polarity.
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.
