3.17 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.
