4.08 Wire Reel Brake
The wire reel hub incorporates a friction brake which is adjusted during manufacture for optimum breaking. If it is considered
necessary, adjustment can be made by turning the large nut inside the open end of the hub clockwise to tighten the brake. Correct
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.
!
CAUTION
Overtension of brake will cause rapid wear of mechanical WIREFEED parts, overheating of
electrical components and possibly an increased incidence of electrode wire Burnback into
contact tip.
