Thermal Arc 186 running off a Miller Bobcat 250

I was looking at Miller Tig welders in the $2000 price range, and I got ste
ered to a Thermal Arc 186 at my local welding supply.
Is there likely to be any problems with using the Miller's 220 plug with th
e one on the Thermal Arc 186. I could not find any plug specs. Also, any op
tions about the Thermal Arc 186. It seemed about $300 less the the equivale
nt Miller model. Thanks for any advice.

The Thermal Arcs are good, but Miller inverters are some of the best in the world. Thermal Arcs used to be a lot cheaper than Miller so it made sense. With only $300 difference I would go for the Miller.
The only technical ding I have against Thermal is the make you buy a separate pendant controller to access the sequencer, where Miller lets you use the foot pedal.
Also Miller Maxstar and Dynasty 200's can run from any voltage: 80 to 500 volts, single or 3-phase, 50 or 60 Hz.
Thermal Arcs in that range are limited to 220v single phase.
I have owned a Miller Maxstar 200DX for 14 years and it has been a flawless machine.

Ernie, can you confirm this, that I can plug a Maxstar 200SD into 110v and it will work? How many welding amps can I get from a regular 110v 15A circuit?
I have two Maxstar 200SD's and I may keep one, I am very tempted to do so, ESPECIALLY if I can get meaningful welding amps from 110v, like at least 80 amps.

I used my Maxstar 200DX for years doing location TIG and stick welding for structural steel, breweries, and on ships. I ran mine from 110v, 220v Single, 230v 3ph, 440v single, 460v 3ph and 575v 3ph. They sound really weird plugged into 3 phase, but run great.
Plugged into 110v you only get about 115 amps out of it, so you can run 1/8" 7018 and 6010, but just barely. I preferred to run 3/32" rod if all I had was 110v feed.
