What to do if the fan is working but I can't hear the HF arc striking and wiping arc welding won't strike an arc on my wsm 200M?

  If the fan is working, the abnormal indicator is not lit, you can't hear the sound of HF arc striking, and wiping arc welding can't strike an arc, it could be due to several reasons. The circuit might be broken, or the silicon bridge might have poor contact; measure the voltage of the positive and negative electrodes from the power board to the VH-07 insert of the MOS board with a multimeter – it should read DC 308V. Also, some of the four high electrolytic capacitors (about 470UF/450V) on the power panel might be leaking. The auxiliary power could be out of work, in this case contact your dealer. Check if all kinds of connect and insert cables have poor contact. There could also be a control circuit problem, in this case contact your dealer. The control cable of the torch might be broken.

Why is the output current not stabilizing on my wsm 200M?

  If the output current of your wsm Welding System is unstable or not controlled by the potentiometer, fluctuating between high and low, it could be due to a damaged 1K potentiometer; replace it. Also, all kinds of connectors might have poor contact; check them.

What to do if I hear HF arc-striking but there's no welding output on my wsm 200M Welding System?

  If the abnormal indicator is not lit, you can hear the sound of HF arc-striking, but there's no welding output, it may be because the torch cable is broken. Another possibility is that the grounding cable is broken or not connected to the workpiece. Also, there might be relaxation between the output terminal of the positive electrode, the gas-electricity system output terminal, and the inner machine.

How to fix a wsm 200M Welding System when the power indicator is off and there is no welding output?

  If the power indicator is not lit, the fan isn't working, and there's no welding output, it could be that the power switch is damaged. Make sure the electric wire net connecting to the input cable is working alright. Also, the input cable may have a broken circuit. Make sure if input cable has broken circuit.

Why can I strike an arc with wiping welding but not with HF arc-striking on my wsm 200M Welding System?

  If the abnormal indicator is not lit, you can't hear the sound of HF arc-striking, but wiping welding can strike an arc, it could be due to several reasons. The primary cable of the arc-striking transformer might have poor contact with the power board; tighten it. The arc-striking tip might be oxidized, or the distance might be too far; remove any film oxide from the burner or adjust the distance between burners to 1mm. The switch might be damaged; replace it. Some of the HF arc-striking circuit components might be damaged; find and replace them.

Why is there so much sticking spatter when using my wsm 200M Welding System?

  If you're experiencing excessive sticking spatter and difficulty with the caustic electrode on your wsm Welding System, the electrode might be connected incorrectly; exchange the grounding cable and handle cable.
