Variable or “hunting” arc.
Poor arc striking with sticking or
“blast-offs”, weld porosity, narrow
and ropy looking bead, or electrode
stubbing into plate while welding.
1. Wrong size, worn and/or melted
contact tip. - Replace if neces-
sary.
2. Improper Drive Tension.
3. Worn work cable or poor work
connection. - Replace if neces-
sary.
4 Loose electrode or work cable
connections.
5. Wrong polarity. - Make sure elec-
trode polarity is correct for
process being used.
6. Gas nozzle extended beyond gun
tip or wire stickout too long while
welding.
7. Poor gas shielding on processes
requiring gas. - Check gas flow
and mixture.
1. Improper procedures or tech-
niques. - See “Gas Metal Arc
Welding Guide” (GS-100).
2. Improper gas shielding - Clean
gas nozzle. Make certain that gas
diffuser is not empty or turned off.
Make certain gas flow rate is
proper.
3. Remove gun liner and check rub-
