I got my stick welder off eBay a couple of years back. Cost me $70. $220 amp 3 phase thing. Works awesome. Easy worth tiwce that just as scrap.
Plunger broke off. Some of the welds inside are not too nice. It used to go down to 20amps and with a 2mm electrode you could weld exhaust pipe. Since i welded it up inside it only goes about 40amps. Its ten times the welder my little CIG arc one is.
