Hi guys, I received my 50 amp plasma cutter and now trying to cut with it. Everything is working although the tip that came with it has been rapidly eaten by the plasma arc after a few cuts. Some extra tips will be on order shortly. My technique must be wrong surely. Short of using it as a lightsabre the cuts seem to be a bit rough and I'm wondering how you fellas with plasma cutters are holding the torch to start and then make the cut.
I have read that for thin material <3/16" you can drag the tip directly in contact with the metal and this gives a fine cut but for thicker you lift the torch tip some mm above the surface. The instructions say to place the copper tip in contact with the material to be cut then push the button and off you go.
I'm using the recommended 65psi compressed air supply. It could be oily and / or wet but will this cause rapid tip erosion? Also the electrode seems to burn at the same time.
