SECTION 3
Description of esp-101 modification: The wiring modification redirects the control signal from the ESP-101 internal so-
lenoid, to the pins within the torch connection panel receptacle. The control signal is then diverted to the solenoid within
the Remote Junction Box.
The hose modification (solenoid air bypass) directs the system air supply to the solenoid within the Remote Junction Box.
This ensures air at a sufficient pressure is immediately available to the PT-37 torch.
