Why is there a lot of metal spatter when welding with my Snap-On MIG135?
- P
  Pamela CarrollAug 5, 2025
  Excessive metal spatter during welding with your Snap-On welding machine can occur due to several reasons. It could be that the voltage adjustment switch has a loose contact, requiring you to replace the switch. Another cause might be an improper adjustment of welding parameters; ensure you select the correct parameters using the welding-voltage switch and the wire-speed adjustment potentiometer. Lastly, a poor ground connection can lead to spatter, so check all grounding connections.

What to do if my Snap-On MIG135 Welding machine has no wire feed or irregular wire feed?

  Jonathan McgeeAug 12, 2025
  If your Snap-On welding machine experiences no wire feed or irregular wire feed, several factors could be responsible: * The drive roll might have too large a groove, requiring replacement. * The liner could be obstructed or clogged, in which case you should remove and clean it. * The wire holding roller might not be completely tightened; ensure it is tightened all the way. * The contact tip could be clogged, necessitating replacement. * There might be insufficient shielding gas; try increasing the gas delivery.

  If your Snap-On welding machine supplies limited current, the issue might stem from several potential causes: a blown line fuse (replace the line fuse), burnt out diode or diodes (replace them), a burnt out electronic board (replace it), or loose torch/ground connections/other electrical power connections (tighten all connections).

Why is there porosity in the welding seam when using my Snap-On welding machine?
- D
  Daniel MullinsAug 25, 2025
  Porosity in the welding seam of your Snap-On welding machine could be due to excess oxidation of the edges to be welded; thoroughly clean the edges with a metal brush. Alternatively, the gas nozzle might be partially or completely clogged by spatter; remove and clean or replace it, being careful not to clog the gas outlets.

  Mrs. Sharon Mitchell MDAug 29, 2025
  If the wire jams or entangles between the drive rolls and the torch infeed wire guide of your Snap-On welding machine, consider these potential causes: the contact tip may have the wrong diameter (replace it), the drive roll groove may be misaligned (realign it), or the liner may be obstructed or clogged (remove and clean it).
