Thanks Guys, what are you guys using for coolant ? Also in my post I meant to say 255ext not 355ext �� I thought the 255 differed with the not having knobs ? And being 5 more amps. However in my shop I don’t get into to much more than 3/16 aluminum and 1/4 inch steel. Mostly panel fab with 060 3003 h13 or 5052. And with steel panel fab I’m at no more than 16 gauge 1008, Chassis ate 120 wall. So the Everlast won’t have to work that awful hard. To get the options it has, I would have been purchasing SD cards. And it seems like the Syncrowave has some issues with there PC2 board.
