Rocket Arm Pneumatically
Operated Spot Welder are ideal for mass production, where less
operational efforts are required. Specially designed for sheet metal
fabrication shops, this model can be used for electro brazing, cross
wire welding, projection welding & resistance heating.
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
» 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.
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.
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 ARMS AND ELECTRODE HOLDERS are provided at
