Ok, more pics. I hope I'm not offending anyone. I just have pent up welding ideas that are just now seeing the light of day.
Here is my very first aluminum project. I did it with the spoolgun on the MIG. 1/8" 3003 aluminum cube by 3" square. This sucker kicked my butt. It took a whole day to cut it out with my caveman tools (before the plasma)
The grinder made me look like I knew what I was doing. The welds were ugly before!
I did this to dial in the spoolgun and know what to expect. I had plenty of burn back on the tip and finally got the wire speed set for decent results. There is some porosity, but I think it's from where I didn't clean the aluminum as good as I should have. I do have a dedicated brush for aluminum, so I knew about that from studying my book. Sorry for the huge pic. My pc started to lock up when resizing, so I let it roll.
