WL-SZ-75K three phase secondary rectifying spot we

Descriptions: This welding machine use welding frame structure. after aging. after elimination of stress processed. high strength. low distortion. with anti-vibration and shock with good rigidity to prevent pressurizing. The first sliding stability of electrode welding.the welding machine has the pressure and forging capabilities. with our self developed three phase computer control unit. parts used on the guide rail rolling friction Coefficient and the mechanical pressure compensation device with high flow solenoid valves. so that with the welding machine has a very good mobility. can meet with a variety of materials, welding technology. high quality cold rolled silicon steel welding transformer. lightweight. smallVolume. high insulation level. low Electromagnetic noise. Low loss and high power combined with specially developed water cooled rectifier components and other devices.so the equipment has a compact structure. easy to operation. welding quality is good and so on. Basic characteristics: 1. This welding machine use six-phase rectifying welding current technology. with computer technology control welding transformer. in welded workpieces process quickly average produced heat to make sure small range of heat. guarantee stability of welding products, consistency of welding point and reliability of welding exterior molding. 2. Six-phase rectifying technology makes three-phase power internet loading absolutely balance. low requirement to grid capacity. not produced non-balance impacts. and will not disturb other equipment on grid.secondary loop inductance of a small. system power factors can arrived 0.9. small resistence of welding machine. especially adapt to cycle convex welding and multi-point convex welding. Welded same thick materials used less power.high quality of welding point. compared six-phase rectifying system to other systems. power transformer power and cable cross-sectional area can recuded exceed 4 times.compared three-phase direct current welding system to other AC power circuit. three-phase direct current welding system not produced harmful harmonics. 3. This machine use three-phase power. small impact on grid required grid capacity compared to the same volume of single phase welding machine is much lower. Welding transformer secondary use with a center tap of six-phase half-wave rectifying circuit. provide ripple in the welding coefficient of zero and no direct current power. welding quality and get guarantee. Suitable industry: this series welding machine are widely used to: aviation, aerospace, military, automobile, motorcycle, light appliances, electronics and so on. welding materials: Heat-resistence alloy, aluminum, copper and other nonferrous metals and low carbon steel, stainless steel, galvanized steel sheet. but also welding titanium, niobium, barium, zirconium, tantalum and other rare metals and other multi-layer plate. main technical parameter of all model specification. modelWL-SZ-3×75KWL-SZ-3×80KWL-SZ-3×100Kthe larest welding thicknesslow carbon steel 4+4 stainless 3+3 aluminum alloy 2.8+2.8 brass 1.5+1.5 low carbon steel 4.5+4.5 stainless 3.5+3.5 aluminum alloy 3.2+3.2 brass 2+2 Low carbon steel 5+5Stainless 4+4aluminum alloy 3.5+3.5brass 3+3input powerThree phase four wire rules 380V±10% 50Hzrated capacity250KVA300KVA350KVArated load sustained rate50%secondary voltage adjust class valueSecond classthe largest empty load voltage7.6V8.5V9Vthe largest secondary short circuit current75KA63kA65kAHello!
