4 Heads Point Welding Machine for Metal Equipment This is a special Spot Welding Machine, equipped with one cylinder fitted with 4 welding electrodes per spot, perfectly designed for single-head multi-spot welding of various components. This practical equipment belongs to professional Resistance Spot Welding Machine category, and realizes stable and efficient machining through standardized resistance welding principles. Used for single head multi spot welding parts. As a mature Automatic Welding Machine, it delivers consistent welding performance with automated operation logic throughout the whole working process.
Advantage & Feature:
1, Machine body of thick steel sheet, not easy to deformation
2, Secondary electric conduction parts is style of upper insulation, to avoid short current accident caused by Scrap iron or workpiece.
3, The electrodes of speed can be adjusted at random, to decrease strike or workpiece and noise.
4, Microcomputer control, accuracy and steady, Can store 15 sets welding schedules, to suit different specification products, greatly optimizing the practical application effect of this spot welding machine.
5, Controller can automatically compensate current, to make welding steady. Some material can be preheat or temper.
6, 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.
7, Fast solenoid valve, making welding speed faster, thereby the productivity is higher, therefore decreasing cost.
8, 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.
9, Quality is stable, failure rate is low, therefore machine life is longer.
