New to welding aluminum, let hear your .02

[Olivero]

Yeah, I only TIG so can't say for MIG but I get soot occasionally, normally if there is some trace of dirt on anything, could even be on the rod.

Some soot will be there. 5356 wire has more Magnesium in it so its a little dirtier. Looks like you are doing fine...Bob

Must me doing good, I can't break the weld

Is normal to have all the black soot around the weld in the first picture?

Here's a couple pics

Good set up. Practice on some scrap. Stainless steel wire brush. Acetone to wash where you are welding. Good luck and post some pics...Bob

I'm building an aluminum frame skid fish house and would appreciate any helpful tips.
I'm a DIY with welding experience but the first time I've welded aluminum.
