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.
See section 2.6 System and Optional Accessories for Remote
Junction Box and Extension Cable ordering information.

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.
