Rocker Arm Spot Welder (Pedal Operated)

We offer precision gamut of spot welder (PEDAL) that is fabricated using finest quality raw material. Our electronic control system comprises of STERCO SOLID STATE CMOS INTEGRATED WELD TIMER having timing range 5-99-199 cycles, adjustable in step of one cycle by means of Thumb wheel switch along with heavy duty electromagnetic contactor for switching purpose. Tap changing switch in 8 steps from 50 to 100% for adjustment of welding current. A mechanism coupled switch provided in the machine which initiates the weld only after preset pressure is built up.

The Electrode System
The rocker arm mechanism coupled with foot pedal is specifically used to attain the electrode force. The force can be varied by adjusting the nut provided on the back-rod below the compression spring of rocker arm mechanism.

Cooling System
Arms, electrode holders, electrode etc are water cooled. Water cooled transformers can be availed at an extra cost.

For Fine Control
Thyristor can be used to control heat current from 5 to 95% of the available current. Weld time is also adjustable from 1 to 99 cycles in step of one cycle each. A pair of thyristor can be used for switching purpose instead of electro magnetic contactor at an extra cost.
