A:Features
1, Efficiency high: Can produce 1000 PC/da usually.
2, Rate of loose-weld lower: Only 5 point among 1000 PCS product.
3, Without deformation and discoloration.
4, High energy saving: Energy saving 40% than usual machine.
5, Electrode is easy to change after wear, don't need to change the complete electrode and electrode base, only for electrode parts.
6, Three phase power supply input evenly.
7, Equipped with PLC touch screen, LED display clearly, easy to adjust and operate. AUTOMATIC, equippped with guide rail, PLC controlling, automatic welding.
8, Machine body of thick steel sheet, not easy to deformation.
9, Microcomputer control, accuracy and steady.
10, Water cooling transformer: Use silicon sheets of 15000 gauss permeability to pile up.
11, Fast solenoid valve, making welding speed faster, thereby the productivity is higher.
12, Cylinder adopt high accurate, anti-friction hard material, which is duralumin.
13, Quality is stable, failure rate is low.
B: Application: Suitable for condenser and evaporator.
