Depends on how you are going to use it, and what your budget is. I am not familiar with that machine. I personally have a Lincoln Precision Tig 185, which Lincoln has replaced with the precision Tig 225. Same machine basically but a higher top end voltage. I love my 185 for home use. I would not be afraid of miller equipment I work with allot of it every day at work. I just chose Lincoln equipment because of the specs and dealer support (and pricing) for myself here at home.
Let me give you a few of my thoughts
I looked at the manual for this machine on Millers site and there are a few things I would consider about this machine before purchase.
It's going to be more of a sheet metal machine than a Roll bar and suspension links machine due to it's max output of 150A. 150A will get you to 1/8"-3/16" but it will be maxed out. Anything above that will probably have to be done multi pass
The torch and the ground cable are not detachable- this is not good for serviceability. It will probably have a premium replacement cost. This will limit you also if you want to change to a different style or manufacturer of torch.
The torch is only 12' long- I run a 25' torch to minimize having to move the machine all the time. For this same reason I run a 15' whip on my MIG machine.
The control on the torch is really not an issue it is more a matter of preference and conditions you are welding around. If you are laying under something welding it is hard to work a foot pedal. There is a foot pedal optional for the miller machine. It also looks to have a proprietary plug on it so replacements and options will be limited.
The thing I personally would not like is the lack of manual control for, Post flow, AC balance, and Frequency Control. This stuff doesn't mean much for a beginner but can be helpful as you get more into Tig.
If this is all the machine you would ever need I would not be afraid to get one. I always tend to think of the future. I hate to buy something that I will out grow and end up spending more than if I would have upgraded from the start.
Welders are allot like Jeeps once you get started their's no end lol.
I started with a TSC Hobart 180 suitcase MIG machine Which I still have and use for light work up to 1/4" and a Oxy/Acet set but that started the ball rolling. Now my arsenal also includes a Lincoln Ranger EXT generator/welder with a LN-25 PRO wire feeder attachment 100' power cables, grounds, and gas hose the Precision Tig 185 and tons of miscellanies stuff. Now I'm looking for a Plasma Cutter
Check out the
www.millerwelds.com and
www.lincolnelectric.com Their is good info on both sites. Tips and tricks, manuals specs etc. They both also have a nice monthly e-news letter that has allot of good info.
But the most important thing I can say is BUY FROM A SHOP THAT WILL TALK
TO YOU AND HELP YOU AND WILL SELL WHAT YOU NEED AND NOT WHAT THEY NEED TO GET RID OF OR THEY HAVE BETTER MARK UPS ON. There is some excellent pricing on the net for welders but it's hard to get support from someone states away I have a local shop but prefer to drive 45 miles to someone I trust. These guys have been wonderful to me. /www.aaweldingsupply.com.
