Why does the arc disappear during cutting with my ESAB PowerCut 700 PT-39?

If the arc disappears during cutting with your ESAB Welding System, several factors could be at play. First, worn torch parts may be the culprit, so inspect the torch and replace any worn parts. Overheating can also cause this issue; check if the yellow OVER TEMPERATURE LED is lit and allow the unit to cool down. Insufficient air pressure could be another reason; check the yellow AIR PRESSURE LED and increase pressure if needed. Finally, low voltage on the incoming line might be the cause, so ensure the incoming line is adequate.
