TROUBLESHOOTING WELDS
Good welds have excellent appearance.
To Eliminate Porosity (in order of importance):
1.Turn on gas supply, if used
2.Decrease voltage.
3.Increase stickout.
4.Increase WFS (wire feed speed).
5.Decrease drag angle.
6.Decrease travel speed.
NOTE: Always be sure the joint is free from moisture, oil, rust, paint or other contaminant's.
To Eliminate a Ropy Convex Bead (in order of importance):
1.Increase voltage.
2.Decrease stickout.
3.Decrease WFS (wire feed speed.
4.Decrease travel speed.
5.Decrease drag angle.
6.Check for correct gas, if used.
To Reduce Spatter (in order of importance):
1.Increase voltage.
2.Increase drag angle.
3.Decrease stickout.
4.Increase WFS (wire feed speed).
5.Decrease travel speed.
6.Check for correct gas, if used.
To Correct Poor Penetration (in order of impor- tance):
1.Decrease stickout.
2.Increase WFS (wire feed speed).
3.Increase voltage.
4.Decrease speed.
5.Decrease drag angle.
6.Check for correct gas, if used.
If Arc Blow Occurs (in order of importance):
NOTE: Try different ground connection locations before adjusting procedures.
1.Decrease drag angle.
2.Increase stickout.
3.Decrease voltage.
4.Decrease WFS (wire feed speed.
5.Decrease travel speed.
To Eliminate Stubbing* (in order of importance):
1.Increase voltage
2.Decrease WFS (wire feed speed)
3.Decrease stickout
4.Increase drag angle
*Stubbing occurs when the electrode drives through the molten puddle and hits the bottom plate tending to push the gun up.
