Tig Welding. Questions
I want to start Tig welding.
My current projects include 1/4" aluminum bar, thin SST sheets, and various aluminum bracketry. Plus, various other projects. This is located in a home garage and will see limited use.
-What features do I look for in a AC-Tig welder?
-Do you have a brand and model that you prefer, and why?
-Any recommendations for cheaper online supplies?

I use a miller syncrowave 330 everyday...very good machine.. expensive..you will have a joy with aluminum unless you can find someone (like me) to help you get started.....dont get a cheap machine..you will only regret it later...been there done that....the smallest machine that I would feel comfotable with is the miller syncro 250 very good machine for the money...if you ever need to weld real thick aluminum you can always pre-heat with a torch.....I work at a race car/ fabrication shop and weld aluminum,stainless ,magnisium,and mild steel ,every day.we have 3 miller syncrowave's ,300,330,and 250, miller is a very good machine..pm me if I can help you....

I'm not a pro welder by any means. I have a miller tig at work and a century mig at home. I weld aluminum much better with the mig than the tig, but it took longer to figure out.
I have ordered from this place in the past, but usually just go local for supplies. Just like the auto parts place, once they get to know you, they cut you a break.

I have a very nice Miller Passport Mig welder. I've learned to weld on it, and have done all my mounts in SSt with it.
How would you set it up for aluminum welding? Spoolgun?

Spoolgun is cool, but probably overkill. I needed to get a teflon liner for the gun, straight argon, and a plastic drivewheel, but I have an older Century ewelder. They have since been bought by lincoln and now miller.
Just keep the gun hose fairly straight, and remember hot and fast. thourough prep is a must, regardless of the method. A sandblaster and a spray bottle filled with alcohol worked well for me.
Also, the tension adjustment is very sensitive, and you will get alot of birdsnesting at first. Nozzle dip helps alot too.

Maybe I'll give this a shot for some thick aluminum. I'm thinking about making the next set of mounts in aluminum.

Its a good idea to pre heat aluminum. I usually just hold the torch to it until spit fry's off instantly. I actually learned most of what I know by reading a book from sears, and the monster garage guide to welding.
