WARNING
Replacing Original Machine Torch with TDC RPT Mechanized Torch
Thermal Dynamics RPT mechanized torches have two control wires that are
used for Parts-In-Place, PIP, only. Do not connect these PIP connections di-
rectly into any start input because when the torch parts are in place, the start
signal will always be energized. If the torch parts are not in place but are subse-
quently installed with the start signal energized, the shield cup will complete the
start circuit and the unit will immediately transfer a pilot arc.
