Plasma

Question, have you noticed any difference when cutting an oil filled AC can open with the plasma versus the oxygen torch.

Using the oxygen torch there's an excess of O2 and this makes the oil burn rapidly we'll call it flare, I've suffered plenty of burns from it while cutting into oil soaked heavy equipment that had hidden pockets filled with oil and grease.

No hot oil flare with plasma.

Yeah same here. I cut some with a torch, standing as far back as my arm and torch would extend, and still got some pretty close calls with them flares. With the plasma I get some flames come out of the window ac units every now and then but its really nothing to be worried about. they stop and go out as soon as I let off the trigger too. (usually). Almost had a fire in the truck bed when a hot spark landed on a ripped up label. but that went out before it hit the oil puddle that was right next to it. Also noticed that cutting into 275 gal. oil tanks with plasma is a lot faster and safer as well. even when they're drained they still catch on fire with the torch for a little bit.
