*Machine body of thick steel sheet, not easy to deformation Secondary electric conduction parts is style of upper insulation, to avoid short current accident caused by Scrap iron or workpiece.

*Microcomputer control, accuracy and steady, Can store 15 sets welding schedules, to suit different specification products

*Controller can automatically compensate current, to make welding steady. Some material can be preheat or temper.

*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, struc-

ture is more compact and reasonable.

*Fast solenoid valve, making welding speed faster, thereby the productivity is higher, therefore decreasing cost.

*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.
