Press Type Spot Welding M/C


APPLICATIONS: SpoVProjection 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, eiectrical 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,refrldgerators, 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 II straight electrodes supplied as standard with the machine, Other types available on request.

ADJUSTMENT OF ELECTRODE FORCE: By means of Air Pressure. The force is adjustable and gives a constant force from 1-5 Kg Cm2 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 alter the pre-set pressure is built up.

ELECTRONIC CONTROL: (A) Thyristorised synchronous electronic sequence timer consisting of : Squeeze, weld, forge, off and heat control unit range 1-99 cis.
(B) SOLID STATE 3 Timers provided for squeeze, weld & forge Timings - Short range
5-50 cycles. Long Range1-1 0 seconds.
