K-355 welder is a rail resistance welder introduced from the Soviet Union in recent years. It was developed by Barton Welding Institute of the Soviet Union and has the advantages of light weight, small volume, high efficiency and large welding cross-section. The whole machine has a compact structure and flexible control and is suitable for working on the field lines. The basic parameters of welding machine: Welding transformer: Single phase 150 KVA Autotransformer: Single-phase network Rated voltage: 380V Generator rated voltage: 400V Rated short-circuit current: 70000A Maximum secondary short-circuit current: 79000A Rated primary current: 395A Maximum short circuit Power Consumption: 500KVA Load Continuity Fs = 50% Rated Power 150KVA Maximum Permissible Continuous Power: 106KVA Rated Short-Circuit Power Factor: 0.5 Welder Auxiliary Equipment Power Supply: Three-phase 380V
