Project Description


RWM-4200B type roofing welding machine is a new hot air welding machine we independently research and develop, using advanced hot air heating technology, intelligent electronic temperature control and speed control system, according to the thickness of the weldng material different, by increasing or decreasing the counterweight to adjust the weldng pressure , so as to effectively ensure uniform weldings, high-strength, tear, no leakage. The welder is simple, good quality, high-efficiency, widely used, especially for PVC, TPO, CPE, SBS and other poly waterproofing membrane roofing welding construction,
