Wire feeds, but arc
does not ignite
1. Improper ground connection.
2. Improperly sized Contact Tip.
3. Excessively worn Contact Tip.
4. Dirty Contact Tip.
1. Make certain that the workpiece is contacted
properly by the Ground Clamp and that
the workpiece is properly cleaned near the
ground clamp and the welding location.
2. Verify that Contact Tip is the proper size
for welding wire. If needed, replace
Contact Tip with proper size and type.
3. Check that the hole in the tip is not
deformed or enlarged. If needed, replace
Contact Tip with proper size and type.
4. Properly clean Contact Tip.
Porosity in the
weld metal
1. Shielding gas cylinder is empty.
2. Not enough or too much shielding gas.
3. Dirty workpiece.
4. Gun is being used too far away from workpiece.
5. Polarity is incorrect for the application.
6. Dirty welding wire is introducing
contamination into the weld.
1. Check gas cylinder and replenish as necessary.
2. Check gas regulator to ensure proper flow.
3. Clean workpiece down to bare metal.
4. Check CTWD (contact tip to work
distance) for the proper procedure.
5. Check the polarity and ensure it is DCEP
for MIG and DCEN for Flux-Cored.
6. Make certain that welding wire is clean
and free of rust and residues.
