  • Aluminum Welding

    The shop I work at has a Millermatic 252 with a Spoolmate 200 for aluminum. I am looking at getting a Spoolmatic 15A for it to boost the output. I have projects that have 1/2" thick pieces that need welded. As is I can get an okay weld put down with my current setup for the most part. With preheating the metal most of my welds are good, but then I hit a colder spot and it just blows out and goes to crap. Will the 15A be able to push enough heat to really get a good weld on 1/2"?
