Just bought my 350P from a buddy that owns a pawn shop. I got it home and took off both the lower panels and discovered one of the tubular shaped porcelain conductor RL2 on the main circuit board has been fried right off the board. The 3 main wires feeding into the machine on the opposite side are also burnt looking. The machine was hooked up for 460 service. I rewired it for 230 service and hooked it up to power. The machine works, I tried pulling the trigger and everything seemed to work. After 30 seconds of pulling the trigger I got Error code 7. I did like the manual says and shut off power breaker and then turned it back on. No error 7 now, Didn't come with any wire or tips so I cant weld. I dig place the tip to the ground and it did spark. If it will weld like this does anyone think it will hurt any other part of the machine? Any one else ever had this problem?

It will either work or not. Throw in some wire and let her rip.
Early 350P units had bad boards. Hope you got an upgraded one.
