PROBLEM TO BE SOLVED: To improve the handling property and the weld-workability by a method wherein a resin plasticizing unit which heat-melts a thermoplastic resin is separated from a resin welding unit equipped with a head for applying which discharges a plasticized resin, and the resin plasticizing unit and the resin welding unit are connected with an electrothermal hose. SOLUTION: A resin plasticizing unit 1 which heat-melts a thermoplastic resin is separated from a resin welding unit 3 equipped with a head 2 for applying which discharges a plasticized resin, and the resin plasticizing unit 1, and the resin welding unit 3 are connected with an electrothermal hose 4. Then, a molten resin is fed to the head 2 for applying by a pump for press-feeding of the resin plasticizing unit 1. Therefore, while the resin plasticizing unit 1 which is heaviest is being placed on a floor, a worker holds the resin welding unit 3 only by hand, and a resin welding work can be performed on a wall surface and a ceiling surface. By this method, the resin welding unit can be made light-weight, and the quickness and the the certainty of a resin welding work can be improved. |
