Fox,

Here's a discussion of your topic:

https://weldingweb.com/showthread.php?36555-dc-welding-aluminum-ok-with-mig-but-not-tig

I don't see a clear answer there.

No offense intended but I don't get why anyone would buy an expensive tig machine that can't do a big part of what tig is for, welding aluminum. One of my neighbors has a DC tig machine and it can't weld aluminum. He brings me his aluminum welding. I've had a Miller Synchrowave 200 for about 10 years.

https://www.bakersgas.com/MIL907308.html

It's is an AC-DC tig-stick machine that cost me $1800 including delivery to my front door. I gave the AC buzz box that it replaced to one of my sons. I find that the vast majority of the tig welding I do at home is on aluminum. An example is the aluminum dog carts I make for my wife's competition in a dog sport called "Drafting". At the higher levels of the competition the cart has to be loaded with weight equal to the dog(s) weight, NOT including the weight of the cart for the "field" parts (steep up and down hills) of the events. So a light cart is a competitive advantage. Another example of aluminum welding is on various cart projects like this cold air intake ducting. Only rarely do I tig stainless that uses DC current.

I found that changing the tig ceramic cups to gas lenses improved the quality of my tig welds. I'm an amateur, not a pro, so I'll take every advantage I can find.

No offense taken, Yar. I’m still learning on most of this stuff and hope I don’t regret the decision I’ve made. I was looking at the tig for a lot of thin steel sheet metal work that I plan to be doing in the future. I’ve only welded aluminum once in my life so far. I doubt I will be doing much of it in the future. I’d hoped that this machine would be adequate and I think it will. My pal mentioned the same thing you said about “too bad it can’t tig aluminum” but I think I will be ok with MIG spool for aluminum. I’ve gotten pretty consistent with a MIG. (Not that it’s too hard... 😉)

By the way, those are some nice beads.

My TIG welder is DC and AC. For years I used it for steel almost exclusively, aluminum only a couple times a year if that. Lately I use it for aluminum always and rarely for steel.
All depends on what kind of work you do, sounds like you considered that and picked the right welder.

The spool gun will be fine for 1/8" or thicker aluminum? Splatters and buzzes differently, but welds similar to MIG. Make sure your aluminum or anything you're going to weld, is super clean before you start.

Darn. Now I have to clean my shop if you’re saying super clean... 😉

Hi Fox. Have fun with your new machine. You do good work now just think of the future. Does Everett have a auto darkening helmet yet?

I bought a similar welder two years ago and think it was a good investment.
Now-- about this panel truck?

Looking forward to catching up with you three (+1) in June.
