I learned welding in the maintenance section of a factory I worked at for three years. Â The tool room supervisor was cool enough to let me DIY the work I brought in (uncritical stuff obviously) and gave me welding 101 on setup and skills. 90 percent tig. Â Later I took a community college class but soon discovered that I should have enrolled in an intermediate class. Â It doesn't take much really to school yourself from a book and a basic machine, or learn a bit on the job like I did, Â to achieve that next level and it's a better investment of time and money.
Soon after I looked far and wide for the best value in a tig welder and sprung for this
http://store.cyberweld.com/tharc186acti.html?ref=lexity&_vs=amazon&_vm=productsearchI learned, in the shop and in class, almost exclusively on Miller 250 Syncrowaves and my 185 AC/DC inverter (it was called '185' ten years  back), with a water cooled torch, has never left me wanting more.  I can stick weld with it but rarely have. If I felt the need to build any large fabrication I'd invest in a mig without pause.  Stick is too damn dirty and tig would take all day to do a half an hours' mig work.
This years' Thermal Arc appears to be essentially the same, updated a bit cosmetically, Â who knows how much functionally?, as my 185 ac/dc. Â The new moniker reminds me a bit of Spinal Tap.
"Yes, but this one goes to 186!"
Why they'd add one amp to the designation is bewildering marketing. But what do I know? Â There is a 200 AC/DC in the lineup but from my research and gathering advice (again, ten years ago) Â that model is only a little more capable and rarely on sale. Â The 186 seems to offer economies of scale and marketed to individuals while the 200 is more ofteh purchased by small industries and tool rooms. Â They are of identical quality.
Anyway, Â if the build quality and electronics have been maintained since my model this still remains a hands-down best value. Â Check out comparable models by Miller, Lincoln, Esab, etc and be sure to tally up the cost of all the extras and consumables to get started. Â

Â
All pictured is industrial quality (all of mine was anyway). Â Heavy stamped steel pedal, Â heavy brass Victor regulator and gauges, torch, starter kit of consumables, tungstens, collets and cups, and other pictured. Â
Not to weigh too heavily on perceptions of national skill, but who doesn't? Â My Thermal Arc's electronics were manufactured 100 percent by Sanrex, a very highly respected Japanese manufacturer of industrial electronics. Â I've really put this little tig through the paces in 10 years without a single hiccup. Â It's difficult to find the source of manufacture for many other company's products. Â Many of the Lincolns are rumored to be Italian made. Â I've heard that Miller makes all of their own in Wisconsin and may be a mixture of sources. Â (this is all 10 year old info).
Everything anecdotal tho. Â And Thermal Arc many have changed completely for all I know.
True though what's been said. Â Welding is incredibly freeing. Â I go through quite a bit of rod and consumables and often wonder where it all goes. Â I'm constantly repairing, reinforcing, fabricating jigs, fabricating or modifying tools, etc. Â I remember getting along just fine before I learned to weld but in reality I was doing a awful lot of painstaking and laborious work-around with bolts/rivets/fasteners, bends, hose clamps, mending plates, etc, that most often would have been far better welded. Â For modifying tools alone a tig is handy. Â Customizing sockets, vice-grips, various clamps... some stay in regular use, some are ad hoc tools for one job never to be used again.
I spent a crazy amount of time and wild imagination building my own deluxe water cooler with micropump, radiator, digital temp and pressure gauges, flow meter, adjustable delay-at-break timer relay (so the pump didn't cycle on/off with every lift off of the pedal), filter, reservoir, and body to match the size of the welder and bolt underneath. Â A whole winter of after-work shop time. Â Insane really. Â I'd highly recommend anyone water cooling a tig welder of this power to fill a 5gal poly bucket with distilled water, add anti-fungal, Â snap the lid on, and just set a small positive displacement pump (more common small centrifugal pumps do not have the lift/pressure to overcome lengths of narrow tubing) on top and plumb it to the torch. Â 5gals of water is more than enough mass to absorb anything you'd be doing with this size machine.
Money no object? Â I'd love to have this on my benchtop
https://weldingsupply.com/cgi-bin/einstein.pl?PNUM::1:UNDEF:X:0460150884Just cool looking. Â Integrated water cooler. Â Portable. Â Only marginally more capable than the Thermal Arc at
three times the price (adding gauges, pedal, cables, torch, consumables, etc) Â but just says "Yellow Ferrari"
