Hi Folks!
Looking for first hand experience with AC/DC TIG welders for Al and Ti.
I'm looking to weld mainly 6061 up to max 1/4", some thin wall Ti and
anything in between.
Budget-range $1500 to $2500 max.
Currently dialing in on Miller and ESAB but to recommendations.
Thanks in advance!!

PS: open to used units in the tri-state area, just in case someone is selling.
I purchased a Lincoln square wave tig 200 last year after alot of research. In general it seems that the Miller units are known for great torches and Lincoln is the better welding unit. The things that made me buy the Lincoln over the Miller was that the Miller units in the price range I was looking at ($1500.00) did not allow for changing different individual settings. Everything was automatic on the Miller but individual settings can be changed on the Lincoln without effecting other settings. To me more automation seems more limiting. Miller offers many different torches which is great but the Lincoln torch that came with my unit has a great flexable head to get into tight places too. The other reason I got the Lincoln was that it ran on 120 and 230v. Miller were 230 only. The only thing I don't like about my Lincoln is that you cannot adjust the post flow time and it runs a little long kind of wasting your gas. I almost didn't get it for that reason but all other benefits outweighed this issue for me.

Besides the welder, don't forget more toys...
A gas lense kit can be really helpful. Both being able to see better with a pyrex cup and push out the electrode a bit better with additional the flow straighteners is nice in some situations.
If you're doing a lot of tight work, a CK #9 torch is also a nice piece of kit. A ton of my hours were doing roll cages and one proved indispensable vs. the more standard #17.
I just bought an Everlast digital stick/TIG with pump/tank/water cooler for $1900 on sale. I've used TIG on stainless and aluminum. I've also burned a ton of stick on it. It works great. I'm very happy with the purchase and it has way more features than I will ever use. I love the HF start!
I even managed to get a free bottle of gas from Airgas. The kid only charged me for a refill and threw the tank in my truck. He told me he was supposed to charge me a $400 deposit on the bottle and asked if I worked for corporate. I said no and he said have a nice day.
PS: and thanks to all the other inputs!
I felt it important to note the standard heads on torches regardless of what brand are not movable. They are just copper tubing and can easily break. The I heads are really the only ones that are designed to move..
Regarding brand miller holds 65% of the total market within north America.. That in itself says allot.. I personally like the dynasty 210 but the invertec 205 is good as well..
Thanks for all the inputs, and to my own surprise, I did end up with a Lincoln Squarewave 200. Whereas I still believe that the ESAB is the "better" welder due to the fact it has more adjustability, it lacks service support in my area.
Also, on a 1:1 comparison the Lincoln is equall with the Miller but $400-800 cheaper.
Super happy with my first AC Al welding experience!
Still have to figure out how to deal with the clear anodization, but I think I have found a way - oven cleaner.
Fantastic choice! I have been running a Lincoln Square Wave for 10+ years with zero issues!
If you do any sanding or metal cutting around your TIG machine, the only precaution I would take is to apply a light gauze or fine sheer fabric over the fan/ventilation grates (I actually taped on some 'used dryer sheets' for a time ). It goes a long way towards reducing dust build up inside the unit. I decided to do this after the first time I vacuumed/cleaned inside the machine . This 'filter' has had little to no effect on air flow or cooling, as I rarely ever go beyond 60% amperage capacity.
I have not had good experience with the one time I decided to 'switch' and buy a Miller Inverter TIG. I had to take it back after only 3 days of 'trying' maintain a steady arc. Come to find out the machine was defective right out of the box. The dealer tried it, called the Miller rep and he tried it and they both reluctantly agreed it was defective. They wanted to 'fix it' under warranty and they said it would take 4-5 weeks to repair . I paid for it in full, had it for 3 days and they wanted me to wait a month+ to get it fixed?? ... uhhhh .... nope, give me my refund!!
I basically have the same machine as Mike but mine is a 256 Si which also has a 60 amp plasma cutter.
