"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.
Arms, electrode holders, electrodes etc. are water cooled. Water cooled transformers can be provided at an extra cost.
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.
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.
Additional ARMS AND ELECTRODE HOLDERS can be provided at an extra cost.
