Being new to TIG welding, I did a lot of research and YouTube watching. I created a checklist of what I thought I needed and this was the cheapest on Amazon that checked all the boxes. So far, DC welding has been great. The pedal is only in/off so I haven't bothered with it, I use the already installed switch on the torch. Everything seems to be easy to setup once you understand the settings and this novice has been having great success with it.If I was to have a main complaint, it is with the regulator, it didn't fit my tank and I bought another $25 regulator to resolve the problem.
