I am helping out a friends shop weld good size aluminum boxes and am welding with my dynasty 350 right now but it's way way way to slow and owner said they were wire welding them with spool gun or push pull set up Most the plate aluminum is 3/8 to 7/16 and they have been tacking on 1 in blocks to all four corners on these parts So my question is what set up would work for me ? I don't wanna spend the farm but would like to get a wire set up for this any advise would be great thanks in advance
