adjustment will result in the wire reel circumference continuing no further than 3/8" (10mm) - 3/4" (20mm) after release of the
trigger. The electrode wire should be slack without becoming dislodged from wire spool.

electrical components and possibly an increased incidence of electrode wire Burnback into
contact tip.
