One might think a small machine for a small weld, but in this case a big machine might be needed.I'm totally lo buck.Have an Astro Power Mig 140 110v where 1min is too hot w/.023 wire. (There are 4 settings: 1min 1max 2min 2max)I just found maybe a deal on a Century 170GS which is a 220v 30-170 amp machine. But I'm thinking I need lower than 30 amps - and that Arc Stabilization is also required.Any insights?ThanksTom

Reply:I've done that with Hobart 125s/140s and Lincoln 135's. The trick is to run a bit more wirefeed than you'd need. When you move forward and get a big keyhole forming, whip the gun back over the keyhole and it'll fill in, then advance forward before it melts back through. It's about a 1/4-1/2" forward and back whip motion.The Hobart 125 actually did the best out of all the welders with having a lower bottom end on tap 1. Love that thing for thin buttwelds on car sheet metal. The 140 was too hot on tap 1 for most car sheet metal so it was a lot of whipping back and forth to fill in keyholes. |
