    Why is the arc not stable and the splash is large on my Michigan Welding System?
    • E
      Ethan ThomasAug 7, 2025
      If the arc is unstable and there's excessive splash during welding with your Michigan Welding System, several factors could be responsible. A contact tip that's too large can cause an unsteady current; consider changing to the correct size. A power cable that's too thin might also lead to power deficiencies, so try using a different power cable. Insufficient input voltage could be the culprit; in that case, enhance the input voltage. Also, excessive resistance in the wire feeding can cause this issue. Clean or replace the liner, and ensure the torch cable is properly aligned.

    What to do if the yellow indicator is on in Michigan Welding System?
    • S
      sarahwagnerAug 13, 2025
      If the yellow indicator light is on for your Michigan Welding System, it could be due to several reasons. The voltage may be too high (more than 15%). In this case, switch off the power source, check the main supply, and restart the welder once the power returns to normal. Another possibility is poor power ventilation, leading to overheat protection. Improving the ventilation condition might resolve this. The ambient temperature could also be too high, or you might be using the welder beyond its rated duty cycle. In these last two cases, the system should recover automatically once the temperature lowers.

    How to fix no shielded gas issue with Michigan Welding System?
    • D
      Daniel ParkerAug 19, 2025
      If there's no shielded gas when using your Michigan Welding System, check if the torch is properly connected and reconnect it if necessary. Also, inspect the gas system for any pressed or blocked pipes. Finally, examine the gas system's rubber pipes for any breaks, and ensure everything is connected and firmly secured.

    What to do if the cooling fan is not working on Michigan Welding System?
    • D
      Dr. Barbara FoxAug 25, 2025
      If the cooling fan on your Michigan Welding System isn't working or is turning very slowly, the switch might be broken and needs replacement. Alternatively, the fan itself could be broken, requiring replacement or repair. Also, check for any broken or loose wires and ensure they are properly connected.

    Why Michigan Welding System is not arcing?
    • B
      brandyjensenAug 31, 2025
      If your Michigan Welding System is not arcing, check the earth cable to ensure it is properly connected. Additionally, make sure the workpiece is free from grease or rust; clean it if necessary.
