[QUOTE="thill, post: 495526, member: 4972"] I forgot that you need to use 100% shielding gas. Does NOT work without that. Some use a spool gun, but it's not necessary. You need to maintain about a 3/4" standout, or the aluminum may burn back inside your tip, which is a pain. YouTube Aluminum Mig, and you will see a bunch of videos. That's how I learned. Just remember, if it starts getting too hot, STOP. I find the best way is to work in short, 3-4 second bursts, pause and then resume. Having the heat sink behind is a real life saver when working on thin stuff, like the hull of a boat. [/QUOTE]
