Pneumatically Operated Rocker ARM Spot Welder

We have carved a niche as a Manufacturer, Exporter and Supplier of Pneumatically Operated Rocker ARM Spot Welder in India. Pneumatically Operated Rocker ARM Spot Welder is ideal for mass production, wherever the need of operational efforts is less. These Pneumatically Operated Rocker ARM Spot Welders are specially designed for sheet metal fabrication shops, electro brazing, cross wire welding, projection welding and resistance heating.


  • Construction : The rugged construction of the machine with least moving parts ensures hassle free use along with minimum 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 This special electrode holder clamping system works to increase the current in the carrying section.
  • Electronic & Electrical Control System : "STERCO" make SOLID STATE C-MOS INTEGRATED WELD TIMER with heavy duty electromagnetic contractor 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 pneumatic system comprises 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. This system provides easy adjustment of the electrode force with the help of Air regulator.
  • For Fine Control : A pair of thyristor can be provided for switching purpose in place of electromagnetic contractor 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 Features : Additional ARMS AND ELECTRODE HOLDERS are provided at extra cost.
