Why does the arc not ignite on my LORCH Welding System?
- D
  Danielle BrownJul 26, 2025
  If the arc does not ignite on your LORCH Welding System, there might be several reasons. First, check for proper ground contact. Second, ensure that you are using the correct electrode diameter. Third, the welding current might be set too low, so increase it. Also, inspect the tungsten electrode for soiling or incorrect grinding; regrind or replace it if needed. Finally, verify that the gas volume is set correctly.

What to do if there is no welding current in LORCH MicorStick?
- C
  Caitlin PierceJul 31, 2025
  If there is no welding current in your LORCH Welding System, the ground line might not be connected or could be defective; check and replace it if necessary. Additionally, the electrode holder or torch might be either disconnected or defective; inspect and replace them if needed.

How to prevent pores in weld metal with LORCH MicorStick?
- A
  Angel SanchezAug 4, 2025
  If you notice pores in the weld metal when using your LORCH Welding System, several factors could be responsible. Start by checking the torch and gas nozzle to ensure they are tight; tighten the gas nozzle if loose and replace the torch if necessary. Also, inspect the torch head for faults and replace it if needed. Ensure the workpiece is clean from grease, rust, oil, etc. Finally, consider whether there is a draught affecting the weld and shield the workplace if necessary.

Why do the displays remain dark on my LORCH Welding System?
- A
  Adam MeltonAug 8, 2025
  If the displays on your LORCH Welding System remain dark, it could be due to a defective mains fuse; replace it. Another possibility is a missing neutral conductor or mains phase; check the mains cable and any mains extension cables. Lastly, if the system uses a battery, it might be discharged; check, charge, or replace the battery.

What causes no inert gas in LORCH MicorStick?
- Y
  yjonesAug 12, 2025
  If there is no inert gas flow in your LORCH Welding System, the gas cylinder may be empty; replace it. The pressure reducer could also be defective; check it and replace if necessary. Another potential issue is that the gas valve on the torch may not be opened or could be defective; check and replace it if necessary.

Why is there too little inert gas in my LORCH MicorStick Welding System?
- H
  Hannah SandersAug 17, 2025
  If your LORCH Welding System is outputting too little inert gas, the torch might not be tight, so check and replace if necessary. Also, the gas hose might not be tight; tighten it. Lastly, the pressure reducer could be set incorrectly or be defective; check and replace if necessary.

Why is the TIG electrode melting on my LORCH Welding System?
- D
  doylepatriciaAug 21, 2025
  If the TIG electrode is melting in your LORCH Welding System, it could be because the welding current is set too high for the electrode diameter; set the correct welding current. Alternatively, the polarity may be reversed with the TIG torch connected to the positive terminal; connect the TIG torch to the negative terminal.
