Why are my Air Liquide Welding System welds porous or spongy?

  Katherine ReyesJul 31, 2025
  Porous or spongy welds in your Air Liquide Welding System can be caused by several issues. First, ensure you have an adequate gas supply and pressure. If there are drafts in your welding area, use a screen and increase gas delivery pressure if needed. Clogged holes in the gas diffuser can also cause this issue, so clear them with compressed air. Check for gas leaks in the supply hoses and replace any faulty components. Additionally, a blocked solenoid valve can be the culprit; check its operation by removing the hose connecting the pressure regulator to the power source. Finally, poor quality gas or wire can lead to porous welds, so ensure your gas is extra-dry and consider changing the cylinder or using a different type of wire.

  Reduced welding power in your Air Liquide Welding System can stem from several factors. Ensure the ground cable is properly connected and that the ground clamps are firmly fixed to the workpiece. Check for detached or loose connections on the switches, tightening or replacing them as necessary. A faulty contactor could also be the cause; inspect the state of the contacts and the mechanical efficiency of the contactor. Lastly, a faulty rectifier might be the issue; visually check for signs of burn-out and replace the rectifier if necessary.

What to do if pressing the torch trigger on my Air Liquide Welding System produces no result?
- S
  Stephanie HuberAug 10, 2025
  If pressing the torch trigger on your Air Liquide Welding System yields no result, consider these potential causes. It could be a faulty torch trigger, disconnected, or broken control cables; remove the torch connection plug and short circuit the poles to see if the machine operates, if so, check the cables and the torch trigger. A blown fuse could also be the reason; replace it with one of the same rating. Another possibility is a faulty power switch; clean it with compressed air, ensure the wires are tightly secured, and replace the switch if needed. Lastly, a faulty electronic circuit could be the issue; in this case, replace the circuit.

How to fix irregular wire feed on Air Liquide Welding System?
- E
  Erin BrownAug 15, 2025
  Irregular wire feed in your Air Liquide Welding System can be due to several reasons. Check for insufficient spring pressure and tighten the pressure assembly knob. A blocked wire-guide can also cause this, so replace it if necessary. If the wire groove is unsuitable for the wire or excessively worn, turn the roller over or change it. Excessive braking on the coil could be another cause; loosen the brake using the adjusting screw. Finally, oxidized, poorly wound, or poor-quality wire with tangled coils can lead to irregular feeding. Remedy this by removing defective coils; if the problem persists, change the wire reel.

What causes the gas supply to not switch off on Air Liquide M 132?
- S
  Shirley PotterAug 26, 2025
  If the gas supply on your Air Liquide Welding System does not switch off, it is likely due to a worn or dirty solenoid valve. Replace the solenoid.
