Inconsistent wire feeding or wire not
feeding but drive rolls turning.

OFF. Turn ON the Power Wave

tripped. Reset the circuit break-
ers.
3. The control cable may be loose
or damaged. Tighten, repair or
replace the control cable.

1. The electrode is rusty or dirty.
Use only clean electrode. Use
quality electrode, like L-50 or L-
56 from Lincoln Electric.
2. The contact tip is partially melted
or has spatter. Replace the con-
tact tip.
3. Improper tip, drive rolls and/or
inner wire guide. Verify the prop-
er parts are installed.
