- No welding output but wire feeds normally when gun trigger is pulled.
- Wire feeds but welding output is low causing wire to “stub”. Welds are “cold”. Machine cannot obtain full rated output of 300 amps at 32 volts.
- The output voltage and wire feed is present continuously or pulsing when gun trigger is NOT activated.
- The output voltage is present continuously when gun trigger is NOT activated. The wire is not feeding.
- No control of arc voltage. Wire feeding is normal.
- There is no gas flow when gun trigger is pulled. Wire feeds and weld voltage is present.
- No control of wire feed speed. Other machine functions are normal.
- There is no wire feed when gun trigger is pulled. Normal open circuit voltage is present.
- The machine stops feeding wire while welding.
- The arc is unstable and or “hunting.”
- Weld bead is narrow or ropy. May have porosity with electrode stubbing into plate.
- The contact tip seizes in the gas diffuser.
