Pro-spot’s NP-3 Nitrogen Plastic Welder uses hot nitrogen gas to restructure common plastic components in automotive repair, from cracked bumper cover surfaces to hinged tabs. It is very easy to use with a short learning curve. The unit has digital controls for adjusting air, nitrogen flow, and temperature settings. A unique feature of the NP-3 is that it is designed to save nitrogen gas costs. The NP-3 blows compressed air through the gun until you push the weld trigger, then it automatically switches to nitrogen gas. When the weld trigger is released, it switches back to air. This minimizes gas consumption. The NP-3 kit includes various plastic welding necessities such as thermoplastic filler rod, aluminum tape, and fine grit sandpaper. The welder works with 110V or 220V and is extremely portable.
