Need new welder

Don't laugh...I bought one of these for work since we were in a pinch on a project requiring small stuff. https://www.amazon.com/dp/B01I6O8ANU/?tag=joeychgo-20 This thing kicks ***. My hardcore welders love it and they have only used big red and big blue for 30 years. It's not an inverter..it has an AC power supply/transfomer and it's heavy...so not very portable and requires 220 1ph. I got one for my home shop and I even have a Ltec 250. I use it almost exclusively now. Wheels around my 3 car shop and reaches every corner with a #10 SJO cord! I can't do that with my 250amp!! No joke.
