Just my luck, plasma cutter just died between cuts on a project I am trying to get done. Right now when the trigger is pressed air comes out of the torch but there is no pilot arc and the "cup" yellow LED flashes. I can feel the electrode move in the head so I can tell that it is not stuck, and loosening the cup with the machine idle makes the "cup" led turn on solid so the switch in the head seems to be working.
Opening the machine I found there is a burned transistor on the main board, looks like a leg burned off. Sticker on the board is PN 234264B, and just found that the replacement board PN is 239900. I only use the machine as a hobbyist and cant believe the machine failed with the light work I have given it. Are these repairable or do I have to buy new?
