"pulse method" for thin stuff works a treat..

and what i did for my 220v was to solder on a "dryer plug" that is- i can plug my 220v MiG or my 220v stick welder right into the wife's outlet for the dryer! one of the things i had to do was get a HD 220v extension cord that allowed me to run the stick welder out in the driveway when working on frames and such.. i spent another $40 bucks or so to buy a box with a breaker at the correct amperage, so i have the end that plugs into the dryer outlet running to a breaker box with a breaker to protect my welders ( hanging on the wall not 12" from the dryer outlet haha!)

then the extension cord comes out the other side of the breaker box, and runs my welders up to 40 feet down the driveway.. super duper handy for welding in the driveway instead of the garage. indispensable for building trailers or fixing broken frames on race cars / 4x4's

HD 220v extension cord.. breaker-box with the appropriately amperage rated breaker to keep your welder(s) from getting too much juice and frying- then just plug your extension cord into the dryer outlet and have at it! good times, good times...
