Burnback Control

Ref. ST-119 647-C / SB-191 630

Burnback circuitry keeps welding
wire from sticking to workpiece
after arc is extinguished. This
circuitry keeps weld output on
welding wire from 0 to 0.25 seconds
after wire has stopped feeding. This
delay action permits welding wire to
burn back to a point where it neither
sticks to workpiece or contact tip.

To adjust burnback time, open front
access door.
