Spot Welding Machine

"Modern Machine Tools" pedal operated rocker arm type spot welding machine are offered in 6,8,10,15,20 and 25 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

TRANSFORMER: Low leakage (High Linkage) design, proper cooling and insulation including winding impregnation to enhance reliability and service life.

CURRENT CONTROL Current seting from min, to max. value can be done by a 6 position, off loap 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 comression spring mounted on a pressure rod with caliberated nut. Here a special arrangement in the machine minimises operator fatigue and ensures simple seting.

COOLING Electrodes, holders and arms are provided with water cooling arrangement with hose connections. (Water supply to be attanged 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.
