I bought three of these welders after speaking to Nick at Canaweld six months ago. I'm tired of buying Lincoln welders full of Chinese parts that fail even with a 3 year warranty. You're still working two weeks as a welder. Welders work an average of six hours a day. We used solid .35 wire and .045 wire seems smaller than wire. You can certainly increase the duty cycle with 0.045 wire, but choose it and you can work all day. Welders aren't advertised as TIG welders, but I turned on a stainless steel TIG torch and did a great job! After opening one, I found no replacement parts from China. The only thing that comes close is the Taiwan-made regulator. I have no problems with other countries, I just need quality. And as little downtime as possible.
