Why is the welding current unstable and uncontrollable in my BOC Welding System?
Unstable and uncontrollable welding current in your BOC Welding System can be caused by a loose or damaged potentiometer, a leaking or damaged filtering capacitor PZ01-005-O1 in the bottom board, or a welding cable that is too long and thin. Check and remove the potentiometer and the filtering capacitor. If the cable is the issue, increase its cross section.
What to do if the BOC Welding System starts arc normally, but the weld appears black?
If your BOC Welding System starts an arc normally but the weld appears black, the solenoid valve might be jammed or damaged. Try cleaning it. Also, the solenoid valve relay (PZ01-005-W K1) could be damaged, requiring a check and possible replacement. Additionally, inspect the torch for wear or damage and replace if needed. Finally, the tungsten electrode might be in poor condition, or the shielding gas could be incorrect, so replace them.
How to fix a BOC Welding System when the torch switch has no response?
If the power indicator, meter, and fan work normally on your BOC Welding System, but the torch switch has no response, the switch of the torch or the cable could be loose. Check and remove. Also, the gas socket might be loose, or the cable could be broken, so check and remove.
