Aluminum welding is a treat when compared to carbon steel. Why? Because it weighs less than steel. That makes my back very happy.
This project took a couple of weeks. We fabricated 2 boxes, 2 pans, a cover and a push rod for a large pipeline company. The 6061 aluminum was 1/4″ thick. We used our new XR Aluma-Pro Mig gun from Miller. The push pull gun really made it easy to run those 30″ beads. We also used the Dynasty 350 with a 1/8th” tungsten. Anything smaller just balled up at 210 amps.
