OK,
I have negotiated a sale price of $1000.00 for the machine (1996 model) which has the wire feeder and all hoses, etc. The owner says it runs fine on 440 power source. But he still says they (whovere they is) tell him it won't run on 220. I've confirmed with MILLER what I already knew, which is they never made a Shopmaster 300 that couldn't run on 220 as well as 440,etc. I'm just wondering what might be wrong with the machine that it won't run on 220? I think they just don't have the jumpers set for 220. The price on it is too good to pass up. any ideas on what other problem it might have.
