This is the Power-TEC Combi Nitrogen Plastic Welder with an integrated nitrogen generator. I use it in bodyshop work to weld filler strips into bumpers, trim supports and to reconstruct missing plastic sections; the gun heats the filler with nitrogen while workshop compressed air maintains consistent temperature between welds and the nitrogen is only released on the trigger. Key technical points are matching filler to the parent material (the supplied strips are PP and many automotive parts are PP) and ensuring correct utilities: 230V supply plus compressed air at 6–8 bar and c.15–20 l/min. The machine is factory pre-calibrated and has a defined shutdown sequence to protect the gun. In practice the most common faults I see are inadequate surface prep (grease left on the joint), using the wrong filler type, and holding the nozzle too close so it contacts the plastic. Used to the manual and with routine checks of the pressurised filters and ventilation, it provides reliable, strong repairs superior to two-part epoxy or hot-air methods.
