I can see maybe where it has it's place but if I were to do any work away from a shop id still have to go engine drive. Lasts longer, more amps, more control. Probably not worth it for the price either.
A student now but really want to weld everyday. Want to learn everything about everything.
warning!! Bad English may be in post. It's off a phone/autocorrect. I've had teachers with worse spelling!
