Reply:You want a low alloy steel wire for welding auto body panels?
Reply:Hey 55 dude,Just offering some "food for thought" so you can approach your repairs and restore with sound results. I do restoration work on 4-10 classic cars each year and all the panel replacement, ie. floorpans, body panels, kick pads, trunk pans, and other thin panels/parts, I do with a Miller Sidekick 90A MIG. I use .023 ER70S-6, C25(75 Argon/25 CO2), and 15 CFH flow inside and 20-25 outside a building. Panel material is like paper, thin and you will get constant burn-thru unless you practice on some scrap pieces to get the proper heat & wire feed parameters set. Also, I use backing strips of 1/8" aluminum to support the seams and prevent burn-thru and tack every 2" to get correct placement prior to full seam welding. It takes patience and a careful application to get good results. You don't need a lot of power to weld panels. For the heavier metal welding, such as frame mods, I have a 250A spoolgun welder that I can change wire sizes and heat settings quickly and also use C25 gas. Hope that helps a bit....Good Luck....DennyComplete Welding/Machine/Fab.
