I have a Miller at the shop and at the house. You don't need a stick welder unless you're doing heavy frame or construction applications. A "wire" welder will serve your every automotive need. Do not be tempted to buy a cheap flea market, Harbour Freight,Wall Mart type machine. This is one area where you really do get what you pay for. There are a ton of 300 dollar Chinese crap pieces out there that make splashy, lousy, joins and frustrate the bejesus outta you with wire feed jams and such. Save up or look used, but get a good machine. It will make you a better welder, and you'll produce better, cleaner work... but you said you were a welder didn't you. You know all this already. Any help I can give... don't be shy. Wayne
