That is a rehashed longevity tig welder. The welder is a giant paperweight do not waste your time. Pedal is garbage, arc control suck sat low amps. Personally I have used one for some odd jobs at work and I would avoid it. Btw the fittings are not Miller/Lincoln universal. There a weird style converter fitting pure garbage.
Seriously look into a Lincoln 225 used we have bought them for under $1000 and beat them hard fan running almost all day on some projects, biggest issue is Lincoln's weak pedal connector that can cause issues when it wears out.
I have used almost every random tig brand from hf tig box, longevity (3 models), everlast, thermal arc, Miller, Lincoln, ect. If a/c is a must have honestly go name brand used. You will thank me.
