Product Description

MACHINE BODY: Reinforced fabricated steel structure with louvered covers for well ventilation. A heavy machined bracket is provided on top of the frame for rocking the upper arm holder carting. The long solid channels at the bottom of the frame increased the inertia and helps to operate the machine even without foundation, Two eye hooks are provided on top of the frame for loading and unloading considering the centre of gravity of the machine.

WELDING TRANSFORMER: Special design technique adopted offer maximum efficiency of the transformer. Sandwich construction of coils help to increase the coupling between the windings. Primary and secondary conductors are selected to suit the heavy demand current. Vertically rolled electrolytic copper bus bar is used as the secondary. Transformer core is made out of cold rolled grain oriented lamination sheets to reduce the core losses. Class F insulation material used in the transformer help to withstand upto 155oC. The coil assembly is varnished in F 50 varnish and vacuum impregnated.

LOWER ELECTRODE SYSTEM: Consists of face place, lower arm holder, lower arm, electrode holder and electrode. Face plate and arm holder are made out of copper alloy castings. Face plate is provided with special 'C' slots which help for easy movement of lower arm with a finger touch for electrode alignment. Specially drawn brass bar with water cooling arrangement is used as lower arm. A chromium copper tip with Morse Taper 2 is used as lower electrode. Since the electrode hardness is maintained to Rockwell B Scale 68 - 70, it offers very high resistance to wear and tear thus increasing the life.

UPPER ELECTRODE SYSTEM : Consists of copper flexible link, upper arm holder, upper arm, upper electrode holder and electrode. Upper arm holder consists of two separate machined halves clamped together to ensure more flow of current. Upper arm, electrode holder and electrode system is same as that of lower system. The whole upper arm assembly is rocking with the help of an axle shaft provided in the upper arm holder casting. Since the axle shaft is provided with grease nipples on both the sides, it offers friction free rocking.

ELECTRONIC AND ELECTRICAL : Consists of precision solid state timer, heavy duty electromagnetic contractor, tap changing switch, limit switch, toggle switches and indicating lamps. Control panel is mounted inside the frame and all the components are easily accessible. The control knobs and switches are on the front side. The standard timing range of the timer is 2-30-300 Cycles.

PEDL MECHANISM : Consists of a 'U' tube pedal connected to a solid bracket to avoid lateral play and bending moment taking place during the operation.

ELECTRODE FORCE: The electrode force is attained through the rocker arm mechanism coupled with the back rod and pedal. As soon as the pedal is pressed the back rod starts traveling upward whereby a sensitive compression spring transmits the potential energy to the above rocking mechanism and the required force is obtained at the tip of the electrode. A nut is provided on the back rod below the compression spring to adjust the electrode force. As soon as the pedal is released, two tension springs uniformly coupled on the back rod return the pedal back to the original position.

COOLING SYSTEM: Arms, electrode holders, electrodes, transformer etc. are water cooled. All the water connections are terminated on the side cover.

WELDTRONIC RANGE OF PRODUCTS : Spot welders; welding heads, projection welders. Seam welders, Side seam welders, Heavy duty butt welders, Heating machines for forging. Brazing machines, High frequency induction heating machine. Sequence control panels. Furnace transformers, Arc welding machines. Argon arc welders etc.
