hi im having a problem with my cutter not turning off i have the 30i razor weld no i dont have a 2t/4t switch on the front panel the g codes are correct and turn the torch on and off when it is supposed to according to the g codes but after the first cut the torch stays on arcing across parts i dont have a filter element on yet would that be the problem i also found on here something about a resistor but wasnt sure if that applied to the 30i any thoughts?
