Single pole single throw switch. Over-tightening the cap and under tightening the cap can cause faults. Cap should only be snug, just tight enough until the nozzle will not spin. I am only asking because this is the most common thing: are you using the complete T30 consumable stack, including swirl ring, electrode, nozzle and retaining cap? There are no shared parts with the 45 amp shielded stack. Next, are the parts all genuine Hypertherm?. The switch often faults with aftermarket parts. Jim Colt. Hypertherm
