Adjusting the brake drag

CAUTION!
Turn off the power source and the wire feeder.
Brake disc friction should provide enough drag to keep the wire spool from spinning freely
after the wire feed stops.
The brake hub is adjusted when delivered, if adjustment is required, follow the instructions
below. Adjust the brake hub so the wire is slightly slack when the wire feed stops.
1. To increase the braking torque, use a 5/16" (8 mm) Allen key and turn the drag adjusting
screw (1) clockwise.
2. To reduce the braking torque, use a 5/16" (8 mm) Allen key and turn the drag adjusting
screw (1) counterclockwise.
