I've spent the last 20 years in fabrication and am a Corporate Quality Manager for a large mechanical and specialty welding contractor. Lincoln definitely brings the quality into your garage with this machine.
There are a couple of cons even though I gave it a 5 star review. The pulse feature is limited to 20PPS. Usually, this is fine, but if you are really trying to control heat on thin metal, it would be nice to have more adjustability in the waveform(it's currently locked at 50%) and a higher PPS. 99.9% of people will never notice this. As other mentioned, the HF start pulse is probably over 10amps, and on super thin sheet metal this might be problematic. It would be nice to have some adjustability here.
That said.... if you want those 2 very small quibbles, you can step up to the Miller at almost 3X the cost.
A few things to be aware of: 1) While you can set the pulses per second, you cannot change the time on pulse and the background amperage. Default is 50% on pulse and 50% background amps and can't be changed. Wish this was configurable. 2) AC frequency goes to max of 150 hz. Not bad but not has high as a few other higher priced TIG welders.). 3) Starting amps seems a bit high and not configurable. I think it starts the arc with somewhere around 15-20 amps - a bit high for some things. On the Lincoln Precision TIG 275 I used at welding class, we could start the arc down at 2 amps.
These are just niggling little items and not a huge deal, especially for the price and quality of this machine. I would like the other features but don't want to pay an extra $2,500 to get them. Overall very happy with my TIG Square Wave 200.
