My first tig welder was a Miller Syncrowave 250 and I bought it back around 1993.
Later on I sold the syncrowave 250 and bought a Miller Dynasty 200dx right after they came available.
On thru the years I have had the opportunity to weld with quite a lot of tig welders. Miller, Lincoln, Ltec, Hobart, Thermal Arc, Everlast, HTP, AHP, and a few I probably forgot.
But one question I get asked more often than any other is " What is a good and affordable Tig welder?" or "What are some affordable tig welders that have good reviews?"
Its a hard question to answer but I hope this series on tig welders will help to answer some of those questions.
pros and cons of the Lincoln TIG 175
pros: simple, durable, affordable at around $2000, good stick welder, auto ac balance, good starts on both ac and dc
cons: discontinued, weight is around 185 lbs, draws more power than inverters, max amps is only 175...
(but adding helium helps a lot) post flow is fixed at 15 seconds which can waste quite a bit of gas.
Miller Diversion 180 pros and cons
pros: simple to use, foot pedal is small and smooth but cable and connections are kinda weak, price is pretty good for a miller brand machine at around $2000
cons: fan is loud, ac balance is fixed at 70% negative and frequency is fixed at around 120hz , torch is hardwired ( I know folks who swapped out the miller torch for a CK flex 17 but it takes some work) torch and torch thumb wheel is sorta clunky.
pros: price is around $1700 on amazon.com, comes complete with torch, foot pedal, etc. 5 year warranty, excellent arc on ac and dc, low amp arc starts are good, full featured machine with advanced pulse.
cons: lesser known brand, foot pedal is just ok...not great. learning curve on controls and features.
