Does anyone have pics and or specs of the Push/Pull? Or is it not being sold yet. This will be strictly for aluminum applications building boats/aluminum Fab.. I have been using a 250Ex for 4 years and it still runs good. Getting ready to build another boat here in the next month and was going to sell my miller and get a newer pulse machine from Miller or Lincoln. Just happened to see this new welder with a push/pull set up. Very intrigued need more info.
