Why does my OEM Tools 24819 need extended contact for a weld?
- M
  Melissa CruzJul 28, 2025
  If your OEM Tools Welding System requires extended contact to create a weld, it could be due to several reasons. There might be a coating on the workpieces that needs to be removed by sanding. The tongs may have deformed or accumulated build-up, requiring you to dress or replace the tips. The material might be too thick, exceeding the welding capacity. Alternatively, there could be poor contact; refer to page 5 for pressure adjustment instructions.

  Alyssa WhiteAug 2, 2025
  To prevent burning holes through the workpiece(s) while using the OEM Tools Welding System, consider these factors: Misaligned tongs can cause irregular heating, so refer to page 5 for realignment instructions. A weld time that's too long can also cause burning, so shorten the contact period. Also, check if the electrode tips are deformed or have build-up; if so, dress or replace them.

Why are the electrode tips overheating on my OEM Tools 24819 Welding System?
- T
  Tammy AguirreAug 7, 2025
  Electrode tips overheating on your OEM Tools Welding System can occur due to several reasons. The tong pressure might be too weak, so you should refer to page 5 for pressure adjustment instructions. If the weld time is too long, shorten the contact period. Also, if the material is too thick, remember that the combined workpieces cannot exceed the welding capacity; see specifications on page 2.
