The DF-EZN1G EZ Nitro Plastic Welder Generator eliminates the need for refilling nitrogen tanks and takes up less space in the shop thanks to its onboard nitrogen generator. The proprietary Flow Adjust Switch Technology (FAST) system makes the DF-EZN1G one of the easiest nitrogen welders to learn and use. It simplifies nitrogen welding and eliminates flow adjustments by the user. According to Dent Fix, this significantly reduces the time needed to set up the welder. A high-pressure N2 Outlet gives you the ability to attach air-powered tools to the side of the unit.
