COURSE OF ACTION
The feeder does not power up: no
cold feed.
Inconsistent wire feeding or wire not
feeding but drive rolls turning.
The wire feed speed is fast (maxi-
mum) and there is no change when
the wire feed speed knob is adjust-
ed.
The POWERBrazer stops feeding
after a few seconds. After a while, it
will begin to feed again when it has
been retriggered.
1. The PowerBrazer is unplugged.
2. The power switch is turned off.
3. The circuit breaker tripped.
4. The motor is not receiving power.
1. The gun cable is kinked and/or
twisted.
2. The wire is jammed in the gun and
cable.
3. The gun liner is dirty or worn.
4. The filler wire is corroded or dirty.
5. Improper gun liner, tip, drive rolls
and/or inner wire guide.
6. Incorrect tension arm pressure on
the drive rolls.
7. The spindle brake is too tight.
8. Worn drive roll.
1. The tachometer is connected
improperly.
2. The tachometer has failed.
1. The motor has gone into thermal
overload.
1. Plug in the PowerBrazer.
2. Turn on the power switch.

possible. Avoid sharp corners or
bends in the cable.

pressure (40psi or less). Replace
the liner if worn.
4. Use only clean electrode. Use
quality electrode from the Harris
Products Group.
5. Verify the proper parts are
installed.
6. Most filler wires feed well with the
pressure arm set between “2” and

with minimal effort.
8. Replace the drive rolls if worn or
filled with dirt.
