Gray 10kva Water Cooled Spot Welding Machines

Spot welding machines have special type of transformer with high weld abilities for thick material at low speed using short length arms. The unit has robust construction in heavily reinforced welded steel construction. It combines a compact streamlined appearance with maximum resistance to mechanical deflection. The transformer is enclosed in the main frame and is easily accessible for inspection and maintenance.

Features:
* Welding Transformer: Manufactured from high grade materials of electrolytic copper strips and sections, water cooled with class "F" insulation with standing continuous temperature rise of 140A C. The coils are impregnated and tropicalized.
* Current Control: By tap link method with 8 tap adjustments on primary of the main transformer having current control from 50% to 100% in 8 steps.
* Cooling Systems: Electrodes, Electrode holders, Arms, Transformers 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.
