diameter.

Adjustment of the nut with nylon insert will control the Mig Wire Spool Brake. Clockwise rotation of this nut
with nylon insert tightens the brake. The brake is correctly adjusted when the spool stops within 10 to 20mm

becoming dislodged from the spool.
CAUTION
Overtension of brake will cause rapid wear of mechanical WIREFEED parts, overheating of electrical
componentry and possibly an increased incidence of electrode wire Burnback into contact tip.
