Why does my Sealey SUPERMIG230 Welding System produce porous welds?
- JJeffrey HarrisAug 18, 2025
If you're experiencing porous welds with your Sealey Welding System, several factors could be at play. Ensure your gas cylinder is open and the gas flow is correctly regulated. Check for and clean a clogged gas cup, and shield the welding site from drafts that might blow away the shielding gas. Also, make sure the joints are free from rust and dirt. The torch should be held at the correct angle and distance (8 to 10mm) from the workpiece. Inspect hoses, connections, and the torch assembly for any gas leaks, and ensure the gas cup is correctly positioned. Finally, the electrovalve might be faulty and need cleaning or replacement.
