Lurd just twigged what that switch is ...it is a post flow control which sets the time the air runs on for after releasing the trigger as I said try both see which works best but you should not need to set the knob

Dude, you have bought a plasma cutter the similar to mine, I plumbed mine into the air supply at work, turned it on and started cutting 2 mm at 30 amps, I cut 14 mm into a 20 mm mild steel which was impressive. Unfortunatley I blew it up while trying to cut 3mm brass plate. I was running 80psi on the gauge, make sure the water bowl is on the bottom as it acts as a water trap. Otherwise I can't see what you have done different to me.

Kk yea i've made sure i changed it round so is on the bottom hopefully i wont blow it cutting 9mm steel. off outside now to give it another go and have a mess around with the air flow nob

Hi,

it's similar to mine.

Generally I set 20A at 2 bar for thin metal around 1 - 3 mm, 30A at 3 bar for medium around 4 - 6mm and 40A at 4 bar for anything above that.

Always start cutting from an edge or drill a hole if you need to cut in the middle of a plate.

If you see sparks above the plate then you need to turn up the power and air or you need to slow down your cutting speed.

I've cut 10mm with mine but it was slow and a bit raggy.

Regards
Peter
