1, Electrode is easy to change after wear, don't need to change the complete electrode and electrode base, only for electrode parts.
2, Machine body of thick steel sheet.
3, Microcomputer control.
4, Water cooling transformer: Use silicon sheets of 15000 gauss permeability to pile up.
5, Fast solenoid valve, making welding speed faster.
6, Cylinder adopt high accurate, anti-friction hard material, which is duralumin.
7, Quality is stable, failure rate is low.
Application: Suitable for condenser and evaporator.
