Rocker Arm Type Welding M/C


APPLICATIONS: Spot welding, electro-brazing, cross wire welding,resistance heating and soldering.The machines are also capable of welding stainless steel, brass, phosphor, bronze,alloy steels, etc. Specific details can be had on request.


USERS INCLUDE: But are not limited to-general engineering work-shops, makers of furniture, electrical instruments, containers, barrels and drums, telephone, radio communication devices, clocks, kitchenware, textile machinery and spares, automobiles, bicycles, motor-cycles, scooters, auto-ancillaries, toys, air-conditioners, refridgerators, transformers, motor, switchgear, etc. etc.


CONSTRUCTION: Heavily fabricated with streamlined appearance, suitably stiffened at points of stress. The transformer is mounted directly on to the body and the bearings for the arm are provided in the same.


COOLING SYSTEM: Electrodes, electrode holders water cooled, water required to be free from residue forming impurities and at a temperature of less than 30°C. If water temperature is higher, increased water flow is required.


ELECTRODES : One pair Morse Taper " straight electrodes supplied as standard with machine, Other types available on request.

ADJUSTMENT OFELECTRODE FORCE: By means of Air Pressure. The force is adjustable and gives a constant force from 100-200Kgf by Pneumatic
Cylinder, adjusted by Regulating Valve.

ADJUSTMENT OF ELECTRODE STROKE: By vertical adjustment of electrode Holder.

CURRENT CONTROL: By means of 6 tap change links between 50% and 100%.

WELD INITIATION: By means of Foot Switch which initiates the weld only after the pre-set pressure is built up.

ELECTRONIC CONTROL: 2 Timers providedfor squeeze &weld. Timings - Short range 5-50 cycles. Long Range1-10 seconds.
