25, 35, 50 and 75 KVA @ 50% duty cycle.
Air operated stationary press type Spot welders with pneumatic cylinder mounted directly.
Robust construction, streamlined appearance with maximum resistance to deflection. Transformer enclosed in the main frame and pneumatic accessories mounted on the side of the machine and upper and lower arms mounted directly on to the body. Operating control station mounted on the machine clearly visible and within easy reach of the operator.
300, 450, 600, 750 and 900 mm (Machine with other throats also available on request). Welding Transformer: Transformer conforms to IS: 4804 Part-I and RWMA Standards, water cooled, class 'F' insulation with thermoswitch protection for overloading.
Welding current adjustable from 50 to 100% by means of a tap change links.
Transformer, Electrode holders, welding electrodes are water cooled.
One Pair of Morse Taper 2 straight Electrodes supplied as standard with the machine. Machine can be provided with custom-designed spot welding electrodes or welding dies to suit various sizes and shapes of work pieces, and suitable jigs and fixtures for holding, guiding and indexing of the work-piece as required at extra cost.
Upper electrode actuated by a heavy duty 2-way cushioned pneumatic cylinder controlled by an electrically operated 4-way solenoid valve. Compressed air at 1.5 Kg/cm.sq. - 5.6 kg/cm.sq. (20 to 80 psi) acting on the pneumatic cylinder provides electrode force. Machine provided with air filter, air lubricator, air pressure regulating valve, air pressure gauge.
"High Lift" (retractable upper electrode) facility shall be provided by means of special cylinder. A hard/foot operated air valve causes the upper electrode to lift to the top most position for easy introduction of the job into the throat of the machine.
Dual pressure system shall be provided by means of two sets' of regulating and controlling devices and the necessary air circuits. Working in conjunction with special control units, this facility would enable application of a higher force on the job being welded at any point during the weld cycle.
Appropriate Control will be incorporated with the machine as per requirement.
