Plasma OK on Porcelain-Coated Steel?

admin

Does anyone know whether it's OK to cut porcelain-coated or enameled steel (like on a washing machine or other appliance) with a plasma cutter?
Reply:As long as your plasma has a strong pilot arc it will blast through the coating with no issues. You will have to have clean metal for your work ground clamp. Any Hypertherm unit will work.Jim Colt

I was hoping to hear from you.I take your response to mean that it doesn't matter which side – coated or uncoated – I attack with the plasma torch?Also, this won't hurt or prematurely wear out the electrode or nozzle on my PM45?
Reply:Probably be easier going if you start on the uncoated side, last I checked glass isnt too conductive but does melt before steel. That's my thoughts anyway, Jimcolt knows these machines far better than I ever will.
