- Symptoms
- Major physical or electrical damage is evident.
- The machine is dead--no open circuit voltage and no wire feed when the gun trigger is activated. The cooling fan is not running.
- There is no open circuit voltage or wire feed when the gun trigger is activated. The cooling fan is running.
- There is no open circuit voltage or wire feed when the gun trigger is activated. The cooling fan is running. (continued from previous page)
- When the gun trigger is activated and the wire feeds normally, but there is no open circuit voltage.
- Output voltage and wire feed speed is present when the gun trigger is NOT activated.
- The machines output is low. Welds are “cold”. The weld beads are rounded or “humped” demonstrating poor wetting into the plate. The machine cannot obtain full rated output of 200 amps at 22 VDC.
- The output voltage is continuous when the gun trigger is NOT activated. The wire feed functions normally.
- There is no gas flow when the gun trigger is activated . The wire feeds and the arc voltage is present.
- The machine stops feeding wire while welding. When the gun trigger is released and pulled again, the wire feed starts.
- Rough wire feeding or the wire will not feed but the drive rolls are turning.
- No control of wire feed speed. Other machine functions are normal.
- There is no wire feed when the gun trigger is activated. Normal open circuit weld voltage is present and the gas solenoid functions normally.
- Poor arc striking with electrode sticking or blasting off.
- The arc is unstable and or “hunting”
- The weld bead is narrow or ropy. May have porosity with the electrode stubbing into the plate.
- The contact tip seizes in the gas diffuser.
