Welds are "cold". Machine cannot obtain full...57The output voltage and wire feed is present continuously or pulsing when gun trigger is NOT activated.58No control of arc voltage. Wire feeding is normal.59There is no gas flow when gun trigger is pulled. Wire feeds and weld voltage is present.59The machine stops feeding wire while welding.59No control of wire feed speed. Other machine functions are normal.60There is no wire feed when gun trigger is pulled. Normal open circuit voltage is present.60The arc is unstable and or "hunting".61Weld bead is narrow or ropy. May have porosity with electrode stubbing into plate.61The contact tip seizes in the gas diffuser.61The welding arc is variable and sluggish.62The arc striking is poor.62Section G Electrical Diagrams95Tamanho: 2 MBPáginas: 102Language: EnglishAbrir o manual
