I have been welding with various MIG machines for the past 15 years. Primarily with my MillerMatic 210. 99% of my welding is for fun these days, primarily on various offroad vehicles. (Everything from repairs to full custom chassis). With that said, I have always wanted to own a TIG machine for precision work and welding materials other than mild steel. I am pretty set on a Miller machine, but do not know a ton about the current available options. I have used an old syncrowave before, but that was many years ago. I would consider myself a very novice TIG welder, however I have a LOT of MIG experience so am not new to welding altogether.
I am ruling out the maxstar series due to wanting to weld aluminum.
The diversion series looks like good intro machines, however they seem to be pretty limited in their capacity. I am not worried about duty cycle, however being limited to 3/16 on a single pass is not ideal and I fear that I would want to grow into a higher end machine pretty quick.
It seems that the dynasty series are the newest/best that Miller has to offer with the Syncrowave series being the "old tech" - so Dynasty series it is unless someone can make a really great argument for something else?
As far as the dynasty series goes, there seem to be a ton of options.
- I think the 210 would be enough for me. If I ever was going to weld thicker than 1/4 I could make multiple passes, use the MIG welder etc...
- The DX model seems like a upgrade easily for the few hundred extra since I will be doing lots of aluminum
- From what I can tell the CPS option is for the cooler? Can you only add a cooler to the CPS models?
- I have only used an air cooled torch. Is the liquid cooling worth the extra money for someone just playing in their garage and not in a production facility? Its not cheap...
- Foot pedals - worth it? Wireless?
I have no problem spending the money on the best machine for my needs. If I could go back in time I wish I would have stepped up to the MillerMatic 251 back in the day for the infinite voltage control, so I do not want to make that kind of mistake with my TIG machine. However I also do not need to buy things that are really only beneficial in a full time fab shop. Also for example, if you can upgrade to a liquid cooling unit later that would be an option.
Any advice is welcome, talk to me like I know nothing about TIG machines!
Thanks in advance
