Well I had a lot of trouble with the setup for aluminium mig. I don’t have a spool gun just trying to use my smaller torch. After bird nesting about a dozen times I finally got all the details rights. I’m only bird nesting now about one in six welds while annoying I can manage. 22.5V and 450ipm for 0.035 5356 wire and a 1.0mm tip.
Next model I want to build is 2” legs 18” high. That will be to scale. It rotates too on the long axis.
@Dabbler rold me you can weld aluminium without a spool gun just use a bigger tip. I also make sure the wire is loose in the tip after every weld and give it a pull to pull out any slack. After I let go of the trigger the wire often hits the weld pushes back and sticks. I think this causes the wire to kink back in the machine.
Pulling up on the torch at the end of the weld and pulling the wire with pliers helps prevent bird nests.
