- Symptoms
- The feeder does not power up - no display (Digital Models) - no cold feed.
- The wire feeder powers up but there is no welder output when the gun trigger is pulled. The shielding gas flows and the drive rolls turn. (Across the arc models)
- Inconsistent wire feeding or wire not feeding but the drive rolls are turning.
- Wire feed speed consistently operates at the wrong value. The speed changes when the control knob is adjusted.
- This wire feeds but cannot be controlled with the wire speed pot.
- Variable or “hunting” arc.
- When the trigger is pulled, the wirefeeds slowly. (Digital display models)
- The preset voltage does not match the power source voltage. (Digital display models)
- Poor arc starts with sticking or “Blast-offs”, weld porosity, narrow or ropy looking beads.
- No shielding gas.
