Why welding gun lifts, but no weld takes place with Nelson Nelweld 6000?
- M
  Michael SmithAug 12, 2025
  If the welding gun lifts but no weld occurs, several factors could be at play: * **No contact:** Ensure the green “Contact” LED is lit, indicating electrical contact between the stud and workpiece. Remove any rust, scale, oil, water, residue, paint, or galvanization from the stud or workpiece. * **Improper ground:** Verify the workpiece is properly grounded to maintain a continuous circuit. * **Insufficient lift:** Perform a Lift Check to ensure proper lift settings. * **Cable issues:** Test weld cables and connectors for consistent conductivity, replacing any broken components. * **Pilot arc voltage:** Check the gun for shorts if no pilot arc voltage is detected. * **Gun malfunction:** The lifting mechanism may be binding; repair as necessary.

What to do if Nelson Nelweld 6000 Welding System unit goes into thermal shutdown repeatedly?
- J
  Jackie GrahamAug 16, 2025
  If your Nelson Welding System frequently goes into thermal shutdown, consider these possible causes: * **Duty cycle exceeded:** Make sure your application is within the specified duty cycle limits; reduce weld rate if needed. * **Blocked Louvers:** Ensure that the input and output louvers are free from obstructions to allow proper airflow. * **Faulty thermal switch:** The thermal switch may need replacement. * **Contamination:** Excessive contaminants inside the machine can prevent proper cooling. Move the machine away from the contamination source.

  If the welding gun on your Nelson Welding System doesn't lift when the trigger is pulled: * **Dual gun operation interference:** If using dual guns, wait for the other welder to finish before retriggering. * **Shorted gun coil:** Check for a shorted gun coil, indicated by a lit yellow LED D2 on the control board. Correct the short and reset the unit. * **Open gun coil:** Inspect the coil circuit for breaks, including loose connections or broken lines between the gun coil and the power PCB board. * **Stuck trigger:** Ensure the trigger is not stuck or the control cable is shorted, indicated by a lit “Trigger” LED. Release or disconnect the trigger.
