To Reduce Spatter (in order of importance):
1. Increase voltage.
2. Increase torch 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 importance):
1. Decrease stickout.
2. Increase WFS (wire feed speed).

If Arc Blow Occurs (in order of importance):
Note: Try different ground connection locations before
adjusting procedures.
1. Decrease torch 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 torch angle
* Stubbing occurs when the wire drives through the
molten puddle and hits the bottom plate tending to push
the gun up.
Proper Gun Handling
Most feeding problems are caused by improper handling of
the gun cable or electrodes.
1. Do not kink or pull the gun around sharp corners
2. Keep the gun cable as straight as practical when
welding.
3. Do not allow dolly wheels or trucks to run over the
cables.
4. Keep the cable clean.
5. Use only clean, rust-free wire. Lincoln wires have
proper surface lubrication.
6. Replace contact tip when it becomes worn or the end is
fused or deformed.
