1.Electrode is easy to change after wear, don't need to change the complete electrode and electrode base, only for electrode parts, so decreasing the cost. Thanks to the split-type electrode design, this Resistance Spot Welding Machine brings obvious cost-saving advantages in daily parts replacement.
2.Machine body of thick steel sheet, not easy to deformation.
3.Microcomputer control, accuracy and steady. Intelligent microcomputer control system ensures precise and stable operation for this high-performance Automatic Welding Machine.
4.Water cooling transformer: Use silicon sheets of 15000 gauss permeability to pile up. There is cooling water in inside, using full copper alloy core, reducing impedance, improving the utilization of power, 20% duty cycle to ensure the requirement of long time welding, big output power. The useful lifetime is longer, noise is smaller, structure is more compact and reasonable.
5.Fast solenoid valve, making welding speed faster, thereby the productivity is higher, therefore decreasing cost. Matched with high-response solenoid valve, the Spot Welding Machine achieves faster welding cycle and higher production efficiency.
6.Cylinder adopt high accurate, anti-friction hard material, which is duralumin, without rust, lower friction, lower noise and loading is faster, thereby reducing the weld spatter.
7.Quality is stable, failure rate is low, therefore machine life is longer.
Application: Suitable for condenser and evaporator.
