Forney AT-100 100amp 120v welder must see!!
This is the best welder I have ever used! I bought it for $100 on Craigslist but it retails for almost $500. Weighs 6.7lb, requires a 20 breaker (seems to work just fine on a 15 amp though), output is 100 amps DC at aprox. 28 volts. DC welding is almost twice as hot at AC welding meaning this has more power than my 250 amp miller thunder bolt. It is fan cooled with thermal protection. This unit was discontinued and they made a new one I think. ALSO You can buy the harbor freight TIG attachment and this welder can be a TIG welder.
