It's DC only, so not TIG aluminum capable. It can only MIG with a spool gun. I would pass and get a unit with AC TIG and high frequency start.
I've never had much luck with a spool gun on aluminum. Unless your building boats or other really large things. I agree, AC TIG with HF is the only way to go.

I looked through the specs on the Rebel. It doesn't really say that it's a CC/CV machine. But if the MIG it talks about is the Short Arc process, then CV has to be there.

As far as I'm aware, the only way to get anything close to a good quality MIG aluminum weld is with a push/pull gun going through a pulser. I'm sure all the top brands have something that fits that bill. The gun alone for a Miller is almost 2k. The machines that have a pulser integrated are all at the high end of the product line up. None of it is cheap.

I have a Miller 251 MIG so I'm good there. Next up will be a Dynasty 350 for TIG. The Dynasty has AC/TIG and a pulser built in.

Keith B,

The Miller Diversion 165 and 180 both have AC/TIG. They're not multi process though. It sounds like your already set with a MIG machine with the 250 you have.
