The cooling fan is not running.40There is no open circuit voltage or wire feed when the gun trigger is activated. The cooling fan is running.40When the gun trigger is activated and the wire feeds normally, but there is no open circuit voltage.41Output voltage and wire feed speed is present when the gun trigger is NOT activated.42The 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 22VDC.42The output voltage is continuous when the gun trigger is NOT activated. The wire feed functions normally.42There is no gas flow when the gun trigger is activated. The wire feeds and the arc voltage is present.43The machine stops feeding wire while welding. When the gun trigger is released and pulled again, the wire feed starts.43Rough wire feeding or the wire will not feed but the drive rolls are turning.44No control of wire feed speed. Other machine functions are normal.44There is no wire feed when the gun trigger is activated. Normal open circuit weld voltage is present andthe gas solenoid functions normally.44Poor arc striking with electrode sticking or blasting off.45The arc is unstable and or “hunting”45The weld bead is narrow or ropy. May have porosity with the electrode stubbing into the plate.46The contact tip seizes in the gas diffuser.46Section G - Electrical Diagrams89Размер: 3,0 МБСтраницы: 99Язык: EnglishПросмотреть
