I-Mig 205P Spoolgun Alum. welding First Time

Looks like that 25.5 is about perfect with just a little preheat. By the midpoint and farther the toes really wetted out nicely. How thick was that plate? It seems like every MIG unit is always a little different for the perfect settings. I know some of that is the analog controls, I wonder if a fully digital unit is also (never used one myself). Is the wire speed you show measured or just from the display? I MIG so infrequently that I always have to check my notes or re-figure out the best settings.

The plate is 1/4 inch thick 6061 this I now and cleaned the surface before welding.Will test with a camera on the welder to see what happens on the readouts. Will have to make drawing for I-Mig face like 250EX for notes.

The 25.5 bead is spread too far, which would indicate it is on the verge of being too hot. The first one has complete wet in of the toes and a true spray. Another issue that may be different and something I can see in the photos you are struggling with some, is the gun angle. It's inconsistent. You should be pushing aluminum.

I am pushing at about 20-25 deg back from 90 deg as up and down and towards me about 10 deg. I appreciate all the help.
Has some ever put pictures of aluminum MiG welding on the forum I have not see any.
Now the big question how do I set up to try the Mig pulse.

[performance]

I'm going to give you a general statement or two, since exact setting results may vary. Pulse MIG is designed to operate by primarily spray arc, but to dip into the globular transfer range long enough to cool the weld but not transfer any metal. Using the basic setup you'll probably push every ounce of power out of the unit to get marginal results at the results you have posted in regular mode. Anything you do will cause the weld to weld cooler so, creating a too big of differential in amps will create issues.
