“RAJLAXMI” pedal operated rocker arm type spot welding machine are offered in 8, 10, 12, 15 & 20 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 impregnation to enhance reliability and service life.
CURRENT CONTROL: Current setting from min. to max. can be done by 6 position off load tap switch.
TIME CONTROL: (With Timer) 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 calibrated nut. here a special arrangement in the machine minimize operator fatigue and ensure simple setting.
COOLING: Electrodes, holders and arms are provided with water cooling arrangement with hose connections. (Water supply to be arranged by the user.)
ELECTRODES: One pair of morse tapper 2 straight electrodes made from hardened copper-alloy is supplied with the equipment. other type or spare electrodes can be supplied on specific orders.
