【High-Efficiency Welding】Hot Air Plastic Welding Machine is equipped with a 3600W dual-stage heating system, delivering a welding output of 2.0kg/h to ensure fast, consistent melting of PP, PE, and other thermoplastic materials. The dual heating design guarantees uniform temperature distribution, reducing weld defects and improving the strength of the final joint. 【Two Welding Tips】Plastic Welding Extruder Machine equipped with two interchangeable welding nozzles, it can meet various welding needs, including PP sheet welding, PE film repair, and plastic pipe manufacturing. This versatility makes it an ideal tool for industries such as chemical, environmental protection, and construction. 【Features】Hot Air Welder have a digital display controller to show welding rod temperature in real time; 360-degree rotating welding head; the motor cold start protection; Independent heating systems of welding rod and parent materials-800w heater for welding rod and 1600w air blower for parent materials. 【Precautions】 Extrude all welding rods which inside the cylinder (when the motor voice getting lighter that means extrude completely), and clean out the welding materials that on the air outlet and adjust the hot air machine to cold wind and cooling the heating element at least 5 minutes before shutdown. 【Wide Application】Hand-Held Extrusion Plastic Welding Machine is used for welding PE, PP, PVC, PVDF, HDPE and so on, for plastic sheets, and bitumen waterproofing and packaging materials with hot air for tanks and lining and agricultural and environmental cover and for polypropylene and polyethylene pipes.
