Special Features :Rocker Arm Type Spot Welders are most suitable for mass production due to less operational efforts, Machine confirms to latest Indian and International Standards. These machines are designed and developed to meet the needs of a vast number of metal fabrication shops.

AdvantagesBesides spot welding the machine can also be used for Electrobrazing, Cross wire welding and resistance heating.

Salient design featuresMachine Body is designed for its ruggedness and easy maintenance. A heavy machined bracket is provided on top of the frame for Rockering the upper arm holder.
"T" stotted face plate allows both vertical and horizontal adjustment of lower arm. Increased current carrying section because of special electrode holder clamping system. Easy accessibility for maintenance of Electrical, Electronic and Mechanical components.

Welding transformerWith special design techique adopted to offer, maximum efficiency of the transformer, confirming to latest IS / 4804 part I. It is Air / Water cooled, sandwitch construction of coils having core of high grade electrical steel. Class ' F' vacuum impregnated helps to withstand higher temperature.

Electrical & electrical control system:It consists of precision Sterco Solid State C-MOS Integrated Weld Timer having timing range 5 - 99 -199 cycles, adjustable in step of one cycle by means of Thumb Wheel switch alongwith heavy duty Electromagnetic Contactor for switch provided int he mahcine which initiates the weld only after preset pressure is built up.

The electrode systemElectrode Forced is attained through the rocker arm mechanism coupled with foot pedal. Electrode force can be varried by adjusting the nut provided on the back - rod below the compression spring of rocker arm mechanism.

For Fine ControlA pair of thyristor can be provided for switching purpose in place of electro magnetic contactor at an extra cost. By using thyristor can be provided for switching purpose in place of electro magnetic contactor at an extra cost. By using thyristor Heat Current can be controlled from 5 to 95% of the current available. Weld time is also adjustable from 1 to 99 cycles in step of one cycle each.

"STERCO" make ROCKER ARM PNEUMATICALLY OPERATED SPOT WELDER are most suitable for mass production, due to its pneumatic operation, less operational efforts are required. These machines are designed & developed to meet the needs of a vast number of sheet metal fabrication shops and can be used for electro brazing, cross wire welding, projection welding & resistance heating.

 

Salient Design Feature

Machine body is designed for its ruggedness and easy maintenance. A heavy Gun Metal bracket is provided on top of the frame for Rockering the upper arm holder. "T" slotted face plate allows both vertical and horizontal adjustment of lower arm. Because of this special electrode holder clamping system current in the carrying section increases.

 

ELECTRONIC & ELECTRICAL CONTROL SYSTEM

Machine consists of precision "STERCO" make SOLID STATE C-MOS INTEGRATED WELD TIMER with heavy duty electromagnetic contactor for switching purpose.

 

Timer consists of squeeze (Range 0-250 cycles, step less control), Weld Timer (Range will be 5-99-199 cycles adjustable in step of one cycle)and to adjust the welding.

 

Current from 50 to 100%, one tap changing switch of 8 steps had been provided on the machine.

 

COOLING SYSTEM

Arms, electrode holders, electrodes etc. are water cooled. Water cooled transformers can be provided at an extra cost.

 

PNEUMATIC SYSTEM

The basic pneumatic system consists of a pneumatic double acting cylinder, solenoid valve of 4 ways 5 port, filter, lubricator, regulator gauge and foot operated initiating switch for solenoid coil.

 

ELECTRODE SYSTEM

The electrode force is attained through the rocker arm mechanism coupled with the pneumatic cylinder. The electrode force can be adjusted with the help of Air regulator installed on the machine.

 

FOR FINE CONTROL

A pair of thyristor can be provided for switching purpose in place of electromagnetic contactor at an extra cost. By using thyristor, Heat Current can be controlled from 5 to 95% of the current available.Weld time is also adjustable from 1 to 99 cycles in step of one cycle each.

 

Extra Features

Additional ARMS AND ELECTRODE HOLDERS can be provided at an extra cost.
