What to do if there is undercut with my CIGWELD Welding System?
- T
  Thomas DyerAug 4, 2025
  Undercut in CIGWELD Welding System can occur if the welding current is too high. Try reducing the welding current. Also, a long welding arc can cause undercut; shorten the arc length. Ensure the electrode angle is correct, maintaining at least a 45° angle to the vertical face. If the joint preparation restricts the electrode angle, allow more room for manipulation. Using a smaller gauge electrode and pausing at the edge of the weave to allow weld metal build-up can also help.

  Porosity in CIGWELD Welding System may be due to damp electrodes; dry them before use. If the welding current is too high, reduce it. Also, surface impurities like oil, grease, or paint can cause porosity; clean the joint before welding.

What causes slag inclusion in CIGWELD Transarc Tradesman HD Welding System and how to prevent it?

  Slag inclusion in CIGWELD Welding System can occur if non-metallic particles are trapped in undercut from a previous run. Clean the slag and cover with a run from a smaller diameter electrode. Ensure the joint preparation isn't too restricted, allowing for adequate penetration and slag removal. Chip or grind out any irregular deposits that trap slag. Use a smaller electrode with sufficient current for penetration, and remove all slag from corners. Clean the joint to remove rust or mill scale that prevents full fusion. Use electrodes designed for the welding position to control slag properly.

Why is there a gap in the root of my CIGWELD Transarc Tradesman HD weld?
- K
  Kimberly LeeAug 22, 2025
  If the weld metal fails to fill the root of the weld in your CIGWELD Welding System, it might be due to a welding current that is too low. Try increasing the welding current. Also, if the electrode is too large for the joint, use a smaller diameter electrode. If there is insufficient gap, allow a wider gap. Finally, ensure you are using the correct build-up sequence.

How to prevent cracks in CIGWELD Welding System weld metal?
- C
  Carmen SchwartzAug 28, 2025
  Cracking in the weld metal of your CIGWELD Welding System shortly after solidification can be due to joint rigidity. Redesign the joint to relieve stress or use crack-resistant electrodes. Insufficient throat thickness can also cause cracking; travel slightly slower to allow greater build-up. If the cooling rate is too high, preheat the plate and allow it to cool slowly.
