The basic characteristics: → The use of six-phase rectifier welder welding current technology, using computer technology to control the welding transformer, rapid and uniform heat generated by welding member to ensure that small heat range, to ensure the stability of product quality welding, weld consistency appearance and reliability of the solder forming effect. → six-phase rectifier technology enables fully balanced three-phase power network load on the grid capacity requirements is small, the impact on the grid does not produce an imbalance, welding machines, electrical equipment will not interfere with other power line. Secondary loop inductance has little influence, power factor up to 0.9 systems, small internal resistance welding, especially for annular projection welding and projection welding, Hunan welding production - Huashi welding, welding the same thickness less material consumption, high joint quality. Six-phase rectifier system compared with other systems, power transformers and power cable cross-sectional area can be reduced by more than 4 times. Phase DC welding systems and compared with other AC circuit it does not produce harmful harmonics. → The machine uses three-phase power, small impact on the grid, grid capacity requirements with respect to the same capacity of a single-phase welder much lower. Welding transformer with a center-tapped secondary use of six-phase half-wave rectifier circuit, provides small ripple factor and no zero crossing of the DC power supply, Anhui welding production welding - Huashi welding, weld quality can be fully guaranteed. Application Number / Patent Number: 201320376519.0 utility model name: crank mobile welder Products: The utility model discloses a bent mobile spot welding, comprising a frame and fixed to the frame of the control box, Qu welding and welding power arm mechanism, bent welding mechanism includes shaft, welding cylinders, welding and soldering copper electrode welding cylinders and welding electrodes fixed to the shaft, soldering copper plate fixed on the bottom electrode welding. The utility model of mobile spot welding bent, Zhejiang welding machine production - Huashi welding, on the one hand, the use of the shaft constituting the mechanical arm, can move automatically or manually moving mechanical way, ensure the accuracy of solder predetermined position. On the other hand, the use of the welding electrodes and welding copper plate under a double-sided single point soldering mechanism, the lower electrode full flat design for surface welding joints more products, but also to ensure smooth surface and welding products consistency points, especially for sheet metal welding to computer chassis, control cabinet, office cabinet and automotive sheet metal welding.
