Actually did a little bit of Mig with a Rebel just today at my LWS. Smooth arc. Nice unit. No internal gas valve for tig:thumbdown: Actually went in to look first hand at a Miller 215, but they didn't have one. Steered me towards the Esab. Guessing they get a better return on those verses blue. About the same money for the Miller, but it has a internal gas valve for TIg separate from the Mig, so no switching between bottles. I'm also looking at the Everlast 211Si, pretty hard. I have a Miller warranty shop here in town, and not having to fiddle with swapping bottles are a plus for Miller, better duty cycle and better price for a complete setup, Mig, Tig(with foot controller)is a plus for Everlast.
