Fixing the wire spool retainer (pre-tension adjustment)
NOTE
Because the spool brake also secures the wire spool retainer, the following steps are to
be carried out for every spool change and before every adjustment of the spool brake.

Securing the wire spool retainer and adjustment of the spool brake
• Open the wire feed unit.
• Loosen the hexagonal socket screw of the securing and braking unit until the screw is free of the
thread in the wire spool retainer (do not remove it completely to prevent losing the small parts).
• Pre-tension the securing and braking unit in the wire spool retainer by screwing the hexagonal socket
screw clockwise, making at least 4 complete turns (4 x 360°).
