- High weld abilities are achieved with special type of transformer.
- Ability to weld thick material at low speed using short length arms.
- In Manually operated machine at low speed using short length arms.
- Easy maintenance.
The unit is of robust construction sturdy heavy rigidly reinforced welded steel construction. It combines a compact streamlined appearance with maximum resistance to mechanical deflection. The transformer enclosed in the main frame and is easily accessible, for inspection.
Welding Transformer :
Manufactured from high grade materials of copper strips and sections, water cooled with class ‘F’ insulation with standing continuous temperature rise of 140`C. The coils are impregnated and tropicalised.
Current Control :
By tap method with 8 tap adjustments on primary of the main transformer having current control from 50% to 100% in 8 steps.
Cooling system :
By tap link method with 8 tap adjustments on primary of the main transformer having current control Electrodes, Electrode holders, Arms, Transformer are all water cooled with one single water-cooling circuit.
Electrode Control System :
Upper electrode is actuated by foot lever or by air cylinder. The electrode force can easily be calculated in both systems. Air system is provided with gauge and manual system with calibrated spring. All air accessories such as filter, lubricator, regulator, gauge, solenoid valve and speed valve are incorporated.
Maximum Operating Speed :
Machine is mechanically capable of attaining 60 spots per minute.
