Spot Welding Machine

» 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. value can be done by a 8 position, off loaf 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 calibrated nut. Here a special arrangement in the machine minimizes operator fatigue and ensures simple setting.
 
» COOLING
Electrodes, holders and arms are provided with water cooling arrangement with host 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.
