UNS-200 × 2-type double-headed flash welder About working principle and characteristics: Equipment 2 sets 200KVA AC adapter for power at both ends at the same time pressed discharge flash upsetting to complete two steel radiator titles and intermediate oval the butt of the tube. Burnt the amount of upsetting the amount of welding current can be set through LCD display. Compared to the the head welder on the market today, the device has the following characteristics: energy saving. The equipment used is 2 sets of of 200KVA exchange solder mask transformer for power, hydraulic station. Other brands is the the two 315KVA transformer and two of the single-phase AC solder mask 18KVA power of hydraulic station. Power transformer welding a column for two seconds, eight hours welding 1000, for example: Division I UNZ-200 * 2 power consumption is about: 200KVA × 2 × 2 seconds ÷ 3600 × 1000 pieces = 222.22 degrees other welder power consumption: 315KVA × 2 the station × 2 seconds × 1000 tablets (solder transformer power consumption) +18 KVA × 2 sets × 8 hours (hydraulic station power consumption) = 638 degrees This shows that, compared to other welding machines UNZ -250AB welding machine which can save up to 65%, and the need to make regular replacement of hydraulic oil. Low requirements on the grid. Only 200KVA power grid to meet. High welding efficiency. Gas-liquid energizing cylinder workpiece clamping is used, the reaction speed is significantly faster than a hydraulic cylinder. Maintenance services. Other welding machine using hydraulic station, its oil line leak problem is more prominent and difficult to solve, and need regular replacement of hydraulic oil, hydraulic station (solenoid valves, tubing, fittings, motor) Division I product point of failure less. The light weight, small footprint. Device model and main technical parameters Model: UNS-200 x 2 Power supply: single phase 380V/50HZ Rated capacity: 200KVA maximum clamping pressure: 15t biggest upset force: 12t maximum short-circuit current: 45KA power consumption: about 0.15 degrees / column welding efficiency about: 5 seconds / column (welding, cutting, not containing feeding time) configuration: Transformers: homemade, "WISCO" silicon steel sheet, epoxy encapsulated controller: homemade, Japan "Mitsubishi" or domestic brand-name PLC solenoid valve: Japan "SMC, Taiwan" AirTAC "burnt bodies: servo motor driven, two sets of SCR: domestic, 1200A gas-liquid force increasing cylinder: homemade, two fitness welders pieces range: low carbon steel unilateral (maximum) cross-sectional area of ??less than 550mm2 column radiator dual titles and column butt at the same time that conventional steel 2 column, 3 column 4 column; the effective welding length (titles hole center distance) to 300mm -1800mm; demand-side conditions: power capacity over 200KVA meet the welder electricity requirements; gas source pressure 0.5MPa, cooling water flow 30L / min; able to meet the conditions of Butt Welding workpiece. column The titles of the same cross-sectional shape, the wrong side of the phenomenon of formation cross section perpendicular to the axis of the tube.
