• Symptoms

  48
  • Major physical or electrical damage is evident.

    48
  • Machine is dead - no welding output and no wire feed when gun trigger is pulled.

    48
  • No welding output but wire feeds normally when gun trigger is pulled.

    49
  • 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.

    50
  • The output voltage and wire feed is present continuously or pulsing when gun trigger is NOT activated.

    50
  • The output voltage is present continuously when gun trigger is NOT activated. The wire is not feeding.

    50
  • No control of arc voltage. Wire feeding is normal.

    51
  • There is no gas flow when gun trigger is pulled. Wire feeds and weld voltage is present.

    51
  • No control of wire feed speed. Other machine functions are normal.

    52
  • There is no wire feed when gun trigger is pulled. Normal open circuit voltage is present.

    52
  • The machine stops feeding wire while welding.

    52
  • The arc is unstable and or “hunting.”

    53
  • Weld bead is narrow or ropy. May have porosity with electrode stubbing into plate.

    53
  • The contact tip seizes in the gas diffuser.

    54
  • The welding arc is variable and sluggish.

    54
  • The arc striking is poor.
