WHITE 6AC 115 VAC N. b) Send 115V from CN9-1 through NC contact on K2 and NO contact on K1 to terminal CN9-2 to initiate Amada welding control and energize RETRACT solenoid valve. c) Amada control will energize retract solenoid to bring electrodes to work position. GREEN/BLACK 115V L RETRACT SOLENOID VOLT- 62AC. d) Retract voltage from 62AC goes through NC contact on relay K1 to turn on relay K2.
