Welding Tips and Tricks

I'm at the drawing board working on a new project. I'm using an old aluminum ramp from a u-haul truck. I'm working with a Ironman 230 and looking for information on what type of aluminum the ramp might be made of and what type of wire I should use?

Welcome to the forum!

For full disclosure, I have not welded aluminum with MIG, altho I know enough to tell you your machine is *capable* of aluminum MIG but may not be *ready* yet. Apologies in advance if you already know that aluminum wire does not behave like steel wire: it is too soft to push through a cable to the MIG gun, so to weld aluminum you'll likely need a spoolgun, which holds the spool of wire so the wire travels 8 or 10 inches to the contact tip instead of 8 or 10 feet.

Also, for aluminum MIG you'll need pure argon gas for shielding, rather than argon-co2 which is common for steel.

So again, sorry if you knew all that stuff already. Do you MIG weld steel now?
