Tomorrow I will pick up my second old Linde Heliarc machine. Can't beat the price on these old welders as long as yu can pick them up and not ship them. I have bought both off Ebay for less than $200 complete with leads, tig torch, ect. At that price I could scrape the copper and come out ahead. A lot cheaper than a new machine for sure. I'd get it in a minute.
