i was looking for easy to use, inexpensive tig welder after taking a class to use for hobby work. So far it is working great, easy to use, no problems encountered. Can't say much about the weld quality, but that is the operator, not the equipment. When i actually do it right, the welds look very nice. i haven't tried aluminum yet, I've just been working on a welding table from mild steel. Then I'll start on some 4130 chromoly & Aluminum practice.
Recommended if you want an easy to use, inexpensive machine.

Got this machine this week, welding steel is an absolute dream. I also have a Hobart Handler 210 with the spool gun for aluminum but wanted to get away from the spatter and have nice clean welds. Aluminum so far has been a challenge. After a few days of practice and getting a different tungsten for the gun and smaller filler rod it has gotten better. After watching a few videos and reading some online forums I'm learning how to weld aluminum much better and I think this machine will be everything I was hoping it would be. Nice machine, but I wish the leads were detachable. Overall, love it!

This does everything I need, and it's a joy to operate. The controls make setup a breeze. It's also a very light unit, at least compared to my Hobart Handler 187, which weighs a ton. The actual TIG welding isn't easy, but this is true of any unit.

The only downside is that it only comes with a 3/32" collet and collet body. If you're using 1/16", 0.040", or 0.20" electrodes, you'll need to order these separately. But they're inexpensive.

I bought this welder to be my hobby portable welder that i'd take to friends garages and weld stuff in their car or projects etc.... This is a miller Diversion 165 with Hobart badges. This welder is a steal because its cheaper than the miller. It is the exact same welder with all the same parts and accessories. comes with pedal, regulator, torch and ground strap. even has tungsten in the torch. you literally can be up and welding within minutes. all you need a a bottle of Pure Argon welding gas from your local welding store and you are ready to weld. This welder is is 165amps I do a lot of welding and rarely do i need to go over 130 amps for most thickness's of metal. I own a miller dynasty 300amp tig welder that sits in my machine shop and i rarely rarely ever need to turn it up past 150amps for thick aluminum. so this little hobart is more than enough for the average weekend fabricator. Do yourself a favor and don't buy the cheap chinese tig welder on eBay or craigslist, they are junk and will breakdown. Hobart is owned by miller and it will last a very long time.

Love this welder! Love it! Welds like a dream. I weld everything and I have 3 wire welders I use on a regular basis. If I were doing real heavy fabrication like 1/4 in or thicker on a regular I would recomend a heavier tig welder like a miller or lincoln with a better duty cycle but 1/8 in and 22 guage welds just beautiful and easy. Definetly recomend for hobiest or light industrial

My son and I are hobbyist welders. We had a Hobart Handler MIG welder, which was an incredible welder, especially since it needed only a standard 110v outlet. When we decided to move to TIG welding, in part because we had some aluminum projects in mind, this is the welder we looked at first. We looked pretty seriously at some less expensive (about $700-800) Chinese TIG welders, but were put off by pretty mixed reviews. We're very glad that we paid a bit more and got the EZ TIG. It does a great job on steel and aluminum (not perfect yet, but that's due to our inexperience rather than the welder). We've used it on steel and aluminum up to about 1/8th inch thick, and it has always worked well. I'd but this again without any hesitation.

This welder is very easy to set up and get started. By selecting the material type and thickness, the welder does all the work in setting up the current levels, AC or DC, pre- & post-flow and other parameters automatically. Just press the foot pedal and start welding. Solidly built unit is easy to carry, mine lives on a cart. The welder comes with a 50 amp, 240 volt plug and cord, but the unit will operate fine on a 30 amp circuit. The cooling fan only operate when actually welding and to cool the unit after a long period of use, otherwise it stays off, keeping dust and debris being pulled into the unit to a minimum. I've tacked thin sheet and welded 1/4" plate so far with this welder and had outstanding results.
