Was purchased at a warehouse auction the welder come on and has a little arc so it needs servicing the gas solenoid valve and water solenoid valve isn't opening not sure if they are getting power to either one of them and the machine is very dusty on the inside so I haven't taken the time to clean it out to see what is exactly wrong with it. The radiator works great I bypassed the solenoid and have it circulating directly to the tig torch and back to the radiator. It has a little arc but I haven't bypassed the gas solenoid to send it directly to the torch because I haven't figured out how to stop from losing so much gas. Servicing this machine is very well worth it but I don't know how or know anyone with knowledge of servicing it. So I'm selling it as is no return I have it plug up now for testing but If someone happens to come over and show me the problem I'm going to keep it.
