 | Features
Compact user-friendly micro controller based circuitry.
Double initiation foot switch, FS1 operates the solenoid valve and FS2 controls welding operation.
Non-Volatile Memory (EEPROM) to store up to 15 weld schedules.
Easy to program with UP / DOWN and ENTER keys. A two-digit LED display indicates set values. Individual operations within a weld schedule indicated by LEDs.
Key lock Switch provided for SET & RUN mode. WELD / NO WELD switch provided on the front panel.
Timings settable in terms of HALF / FULL cycles of mains supply frequency to achieve better resolution. Precise time and energy control ensures consistent weld quality.
Relay contact output provided to actuate the Motor Drive of the welding machine.
