DOWN FOOT SWITCH Cut two wires going from this foot switch to socket CN9 at the back

of the welder and them connect as shown here.

SEQUENCE 1. First time with retract fully open, closing of FOOT SWITCH will: a) Close relay K1. 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. d) Retract voltage from 62AC goes through NC contact on relay K1 to turn on relay K2. e) When the FOOT SWITCH is released, relay K1 opens. f) NC contact on K1 closes relay K2. g) Relay K2 self latches using retract voltage 62AC (retract). 2. Each time the FOOT SWITCH is closed until retract is released: b) K3 ONE-SHOT relay is energized for about 3/4 second to start SOFT TOUCH sensor board through SV

input terminal 9. c) Sensor board turns on SVL to close electrodes under low force and electrodes close. d) If continuity is detected before the time set on the DIPswitch on this board, SVH will turn on to bring

electrodes to full welding force. e) At the same time, the Amada welding control is energized through closing of a NO contact on the SOFT

TOUCH sensor board terminals 6 and 7. f) Voltage on output from welding control terminal 7AC keeps the sensor board energized at terminal SV

until the weld solenoid is released at the end of the weld by the Amada control even if the foot switch is still closed.

g) Pushing the RETRACT release button on the top of the footswitch drops the voltage on 62AC and re-sets the system.

1.If it is impossible to add a tee between the airline filter and pressure

regulator, connect this line to “AFTER AIRLINE OILER”.

2. Remove the existing pressure regulator #9.

3.Remove the existing Remove tubing from the existing SOL1

(originally going to RETURN cylinder port)

4. Eliminate flow controls on top (forward) port and lower (return) port.

REMOVE THE PRESSURE REGULATOR AMD REMOVE PLUMBING FROM SOLENOID VALVE SOL1 (originally connected to lower port of cylinder). CONNECT TUBING A SHOWN TO MATCH CIRCUIT ON FIRST PAGE.
