Looks a bit “cold” but might have been running a bit “hot”? Difference in machines and prep possibly? I’d just like to get rid of the spatter at this point.

I rechecked my voltage and wfs when I got home this afternoon. 22.1 volts/ 420 wfs.

Cj737 Yeah, I was wondering what might help reduce the spatter as well. The sheet material is 3/16” and that’s a piece of 3/4x3/4x1/8” channel in the pictures. I was afraid I might blow through the channel if I turned it up to much. I believe I was running about 20.2 volts, can’t remember the ws. Bi...

Thanks cj737. A ton more clamps and preheating was the ticket! Still learning this aluminum stuff!

I tried my first small aluminum job and the welds are acceptable but the end product is not. I’ve attached a drawing to help understand what I’m doing. The project is meant to be a bridge plate for rolling big freezer units onto an elevator. The freezers have small diameter casters on the bottom the...

Drizzit…Looks like you’ve got quite a project.

Appreciate the input fellas. Distortion of the sheet was my main concern. At my skill level, I think I’d have less overall heat input with mig.

I have a small project coming up and not sure whether to mig it or tig it. Material is 42”x 24”x 0.16 6061 aluminum sheet with 1”x1”x .250 6061 aluminum angle. Welding the angle to the sheet. Only have two to build so not much production. Obviously trying to keep distortion to a minimum. Thoughts?

Glad to be accepted and looking forward to learning different tip and tricks. Question, has anyone used a Millermatic 220 AC/DC on 120v or ran it from a generator? If so how well does it work and will it burn, say an 1/8” 6011 rod on 220v?
