 GENERAL DESIGN
VULCAN Pedal operated Rocker arm type spot welding machines are offered in 6,8,10 and 15 KVA models each with three standard throat depths to cover practically all applications. All machines are made of steel fabricated rigid structures to eliminate the minutest spot deflections.
 
     
 
 SAILENT FEATURES
TRANSFORMER:
Low leakage (High linkage) design, proper cooling and insulation including winding varnishing by vacuum pressurised impregnating system to enhance reliability and service life.
CURRENT CONTROL:
Current settings from min. To max. can be done by a 6 position, off load tap switch.
TIME CONTROL:
Solid State Electronic timer to control weld time from 5 to 50 cycles and 1 to 10 seconds to achieve accurate and repeatable spots.
WELD PRESSURE:
Adjustable max. Pressure levels are derived from a heavy-duty compression spring mounted on a pressure rod with caliberated nut. Here a special arrangement in the machine-minimises operator fatigue and ensures simple setting.
COOLING:
Electrodes, and arms are provided with water-cooling arrangement with hose connections. (Water supply to be arranged by the user.)
ELECTRODES:
One pair of Morse Taper 2 straight electrodes made from hardened copper-alloy is supplied with the equipment. Other types or spare electrodes can be supplied on specific orders.
CABINET FEATURES:
Modern looks, novel design concepts. Epoxy powder coated body for rag rite.
