I had a project on cutting some 1/4” plate multiple times in 42” lengths. I built a holder on a linear 48” linear rail for my plasma hand torch. So I got the rail all set, dialed in the machine for the material, loaded my gun in the rail and went to cut. Starting “off”the material came in and just wasn’t cutting more melting and blowing. Wtf so I figured change out the tip haven’t done that in awhile. So I change out the tip and electrode remount the gun and go at it. Same thing just melting and not cutting as it should. Thinking my machine is toast some board went out and it’s gonna be not worth repairing I look back at the machine to recheck my settings I notice my ground lead coiled up hanging on the machine. Aw gez I cant believe I forgot the ground! What a brain fart I was just happy nothing was wrong with the machine. Got all my pieces cut gotta love the plasma cutter! When the materials grounded
