product description
Medium-frequency Inverter DC Spot Welder, Pneumatic Medium-frequency Inverter Spot Welder Brand: Shanghai Haojing Model: SMD-20 Rated Capacity: 50KVA Maximum Short-circuit Current: 20KA External Power Supply: 380V/3φ Duty Cycle: 50% Maximum Working Pressure: 7.2KN Electrode Stroke: 80MM Cooling Water Flow Rate: 30L/MIN. Our SMD-20 medium-frequency inverter DC spot welder features fully digital control via a human-machine interface touchscreen for intuitive operation. Performance can be expanded through PC programming. Custom fixture designs accommodate diverse workpiece welding requirements, and automated special-purpose machines can be engineered to enhance production efficiency.
Product Overview:
The SMD-20 medium-frequency inverter DC spot welder boasts broad applicability, featuring a compact welding transformer with high output energy. By elevating the welding transformer frequency from standard 50/60Hz to 1000Hz, it significantly reduces core material weight. Additionally, rectifier diodes in the secondary circuit convert AC power to DC for the welder, substantially improving secondary inductance values and saving over 30% in user power consumption.
Product Advantages:
1. High welding stability;
2. Over 30% energy savings, low operating costs;
3. Three-phase balanced input with power factor up to 95%;
4. Lower welding current and electrode pressure requirements;
5. Minimal secondary circuit inductive energy loss;
6. Doubles electrode lifespan, reducing grinding time;
7. Substantially reduces installation costs for electrical systems and auxiliary facilities like water/gas;
8. Enables more precise, rapid, and comprehensive control and analysis of welding parameters.
