In my opinion, the primeweld 225 is one of the best choices in affordable tig welders.
The problem with most other really affordable tig welders is usually a really cheap foot pedal and TIG torch. Primeweld went to extra expense to include a genuine CK17 torch with superflex hose along with a very smooth SSC style foot pedal.
A high quality CK dinse adapter is also included so that you can easily swap out a tig torch or cable when the time comes.
Primeweld also has a responsive primeweld equipment users group on facebook and also has demonstrated great customer support
Watch some more primeweld videos and you will see what I mean.
If you have every looked for a weld calculator for tig welder settings, you probably already know that millers weld calculator falls short for anything outside of fillet welds on the bench.
Welderskills Quick Settings video pages not only share detailed settings, but also show a quick arc shot video showing technique.
There are hundreds of Quick Settings videos on welderskills.com that provide detailed tig welder settings for fillet welds, groove welds, thick, thin, round, pipe, tube, buildup repairs and more on carbon steel, stainless steel, aluminum, titanium and more.
If you are unsure where to start on a new job, these pages can save you some time and frustration.
If you are still using the standard TIG cups and hardware that came with your machine or TIG torch, I can just about guarantee you will get better results if you upgrade to a weldmonger® stubby gas lens kit.
