E-1 THEOR Y OF OPERA TION E-1 WIRE-MA TIC 250 INPUT LINE VOL T AGE AND MAIN TRANSFORMER The desired single phase input power is connected to the WIRE-MA TIC 250 through a line switch located on the front panel. A reconnect panel allows the user to configure the machine for the desired input voltage.
E-2 THEOR Y OF OPERA TION E-2 WIRE-MA TIC 250 OUTPUT RECTIFICA TION AND FEEDBACK CONTROL The AC output from the main transformer secondary weld winding is rectified and controlled through the SCR rectifier assembly . Output voltage and current are sensed at the shunt and output terminals and are fed back to the control board.
E-3 THEOR Y OF OPERA TION E-3 WIRE-MA TIC 250 CONST ANT VOL T AGE OUTPUT The controlled DC output from the SCR rectifier assembly is filtered by the capacitor bank resulting is a constant voltage DC output.
E-4 THEOR Y OF OPERA TION E-4 WIRE-MA TIC 250 WIRE DRIVE MOT OR AND FEEDBACK The wire drive motor is controlled by the control board. A motor speed feedback signal is generated at the motor tach and sent to the control board.
