Spot Welding Machines

Vulcan Pedal operated rocker arm type spot welding machines are offered in 6,8,10 & 15 KVA models each with three standard throat depth to cover practically all applications. All machines are made of steel fabricated rigid structures to eliminate the minutest spot deflections

Salient Features :

• Transformer : Low leakage (High linkage) design, proper cooling and insulation including winding varnishing by vacuum pressurized impregnating system to enhance reliability and service life.
• Current Control : Current setting 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 l 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 calibrated nut. Here a special arrangement in the machine-minimizes 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 of spare electrodes can be supplied on specific orders.
• Cabinet : Modern looks, novel design concepts. Epoxy powder coated body for long life.
