Got my plasma cutter in. The air pressure regulator was broke off. The seller said he would work with me to fix it. I replaced the regulator and it is not working. It wants too but all I get it a hiss then nothing at the torch. Consumables need replaced but it should still fire. Contacts are clean in the torch. I blew out the inside of the plasma cutter. Nothing seems to be not connected. I guess it will be going in the shop. I'm in need of this tool as I am already behind on 2 cars. Anyone have any experience or know where to start solving this problem?
