Howdy Guys, i tig weld alot of stainless small gun parts. i usually use a Miller Econotig and have very good results. i have a friend that has a Airco Dip stick model 160 set up with mig/tig/stick. the machine is mint and he is the original owner. i was thinking about purchasing it. just was wondering if anyone had experience with this type of welder? would it be good tig welding small parts or better than my Miller? any info is greatly appreciated. i have only have used Lincoln and Miller tig machines. thank you

I have never owned an Airco welder, but I know of a few who overworked them and turned them into scrap. If you are lokking to add versatility with the wirefeeder, and you can get it at a good price, it will probably be fine as long as it isn't used for production work. All in one machines are nice for the garage where space is limited, but keep in mind - one goes down, they all go down. If you can pick up a 150 amp MIG, it would complement your Miller, letting you do the less intricate work a little quicker.
I admit to being biased, as all of the welding machines in my shop, from the 150 amp inverters to the 300 amp 3ph. welders and a portable are all blue.
If you are mainly doing delicate work, you should consider waiting for a welder that has pulse. They are not for every one, but if you get an opportunity to demo one at a trade show or at your local Miller or Lincoln store, you will get an opportunity to check out the new technology
BTW, even the econotig won't hold up to continuous high output should you take on larger projects, but should serve you well for what you are doing. I speak from experience. My first welder was an econotig, and used it daily, until I burned it up (I think an Airco owner just went AHA!!!). If you operate any welder within its duty cycle it will pay for itself, but an economy model won't give you the same arc starts and smoothness that you now enjoy.
Good luck, and post the results of your decision.
