6.10 Remote junction box installation

The Remote Junction Box (RJB) provides a means to extend the total length of the

PT-37 Torch. A Remote Junction Box is used in combination with 50’, 75' or 100’

extension cable and any standard length of PT-37 Plasma Torch from 4.5’ to 50’, to

create a combined maximum torch length of 150 feet.

Installation of a Remote Junction Box requires minor modifications to the ESP-101

power supply, mounting of the box itself, and connection of the extension cable. Use

the diagram and steps below for installation.

Note:

Description of ESP-101 modification: The wiring modification (interconnect plug

reversal) redirects the control signal from the ESP-101 internal solenoid, 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.

Remove the top and right side panel of the power supply.
