Plastic extruding welder combine the heat blast warm-up and the welding rod extrusion, the heat blast owns adjustable thermal temperature control and the automatic-sending wind supply, the extruding parts adopt heat blast heating system. Furthermore, the extruding speed can be conveniently adjusted. Adoption of the 220V alternating current supply can weld the thermoplasticity plastics, such as welding of the plastic panel and plastic tubing, especially for sealing of the winding tubing with hollow wall and large aperture, welding of the tubing welding and repairs of the tubing damage.Thermoplasticity plastic HDPE, PP, PVDF, the PE can show the characteristic best. It is forbidden to use for the plastic with electric conduction (PE-EL), which can bring electricconduction short circuit of the machine. This machine is used for the fourth part of the barrelbath and the tube that accords to the standard of the DVS (Germany Welding Association). It can once weld the welding line with width of more than 10mm / Voltage220VDrive Motor800WHeat blast2000WTemperatureWind Temperature20650/Heating temperature while plastic extruding is 20300 Warm-up heat blast volume300L/minDiameter of Welding Rodφ 3.0mm-3.5mm
