  Kirsten WhiteAug 20, 2025
  If your DeWalt Welding System is switched on, the indicator for the selected welding process is lit, but there's no welding current, here are a few things to check: * Ensure that there is connection to the workpiece. * Check the plug connections of the welding cable. * If there is a break in the power cable in the welding torch or electrode holder, replace the welding torch or electrode holder.

Why is there no welding current and overtemperature indicator lit on my DeWalt DCW100?
- S
  Samantha BarberAug 26, 2025
  If your DeWalt Welding System has no welding current, the indicator for the selected welding process is lit, and the overtemperature indicator is also lit, it could be due to several reasons: 1. The duty cycle has been exceeded, causing the device to overload. Keep within the duty cycle. 2. The thermostatic automatic circuit breaker has tripped. Wait for the power source to automatically come back on after the end of the cooling phase. 3. There may be insufficient cooling air intake. Ensure adequate air supply.

What to do if my DeWalt DCW100 Welding System won't switch on?
- C
  Christian SmithAug 27, 2025
  If your DeWalt Welding System will not switch on, it could be due to the following reasons: * The battery has entered a state of deep discharge because it has been stored for too long without being charged. Charge the battery; battery operation is possible again above 25% capacity. If charging is no longer possible, contact authorized service center. * Control panel defective. Contact authorized service center.

What to do if my DeWalt Welding System displays error flashing and mains flashing?
- J
  Jack GarciaAug 29, 2025
  If the 'Error' and 'Mains' indicators are flashing on your DeWalt Welding System, it indicates a mains fault, such as overvoltage or undervoltage. Check the mains supply voltage.

- D
  David FoxSep 1, 2025
  If your DeWalt Welding System is switched on, the indicator for the selected welding process is lit, but there is no welding current and the overtemperature indicator is flashing, it indicates a power module error. Turn off the device, then turn it on again. If the error occurs frequently, contact authorized service center.

What to do if my DeWalt Welding System activates deep discharge protection?
- M
  Margaret Edwards MDSep 3, 2025
  If the deep discharge protection has been activated on your DeWalt Welding System, it means the battery is discharged. Charge the battery immediately. Battery operation is possible again above 25% capacity.

Why does the rod electrode tend to stick on my DeWalt DCW100?
- T
  Travis LewisSep 5, 2025
  If the rod electrode tends to stick when using your DeWalt Welding System, the value of the arc-force dynamic parameter (MMA stick welding) may be set too low. Increase the value of the arc-force dynamic parameter.

What causes poor ignition properties during MMA stick welding with a DeWalt Welding System?
- M
  Monica FigueroaSep 7, 2025
  Poor ignition properties during MMA stick welding with your DeWalt Welding System can be caused by: * Incorrect welding process selected. Select "MMA welding" or "MMA welding with Cel electrode" process. * Starting current too low, electrode sticking during ignition. Increase starting current using HotStart function. * Starting current too high; electrode consumed too quickly during ignition or is generating a lot of spatter. Reduce starting current using SoftStart function.
