hi
plasma cutter worked for 10 to 20 minutes use (not continuous cutting), then wouldn't start an arc.
fan on, air flows, no overload light, no pilot arc and doesn't cut. makes a strange 'buzzy' sound within machine
i have checked the following;
air supply, dry and correct pressure
supply voltage and earth all ok
connections to machine, all seem ok
continuity through two pin switch wire, ok
earth lead good, but this wouldn't effect pilot arc would it ?
also checked red wire which is connected to the 'pilot arc ignitor' on front panel, this has continuity to nozzle. unsure if this is correct
what else can i check or have i overlooked something simple
thanks for any assistance
only got one piece cut out lol
