SECTION 2 DESCRIPTION
WARNING
2.1 General
The patented PT-27 (Figure 2-2) is a manual torch with a 75° head designed for use with several Plasma Arc Cut-
ting Packages using clean, dry air as the plasma gas. The service line lengths available with the PT-27 torch are
25 feet (7.6 m) and 50 feet (15.2 m). The PT-27 torch is rated to operate at a maximum of 80 amperes at 100%
duty cycle.
2.2 Scope
This manual is intended to provide the operator with all the information required to assemble, operate, and
repair the PT-27 Plasma Arc Cutting Torch. For additional safety precautions, process instructions, and system
troubleshooting; refer to the appropriate instruction manual for your Plasma Arc Cutting Package.
2.3 Specifications
Refer to Figure 2-1, Figure 2-2, and Figure 2-3 for specifications.
THE PLASMA ARC CUTTING PROCESS EMPLOYS HIGH VOLTAGES.
CONTACT WITH "LIVE" PARTS OF THE TORCH AND MACHINE MUST
BE AVOIDED. ALSO, THE IMPROPER USE OF ANY OF THE GASES EM
PLOYED CAN PRESENT A SAFETY HAZARD. BEFORE BEGINNING OP
ERATION WITH THE PT27 TORCH, REFER TO THE SAFETY PRECAU
TIONS AND OPERATING INSTRUCTIONS IN THE APPROPRIATE POWER
SOURCE INSTRUCTION MANUAL.
USING THE TORCH ON ANY UNIT NOT EQUIPPED WITH A MATING
SAFETY INTERLOCK CIRCUIT MAY EXPOSE OPERATOR TO UNEXPECT
ED HIGH VOLTAGE.

SECTION 3 ASSEMBLY & OPERATION
3.1 GENERAL
THE TORCH HEAD CONTAINS A GAS FLOW CHECK VALVE THAT ACTS IN
CONJUNCTION WITH CIRCUITRY WITHIN THE POWER SOURCE. THIS
SYSTEM PREVENTS THE TORCH FROM BEING ENERGIZED WITH HIGH
VOLTAGE IF THE TORCH SWITCH IS ACCIDENTALLY CLOSED WHEN THE
SHIELD IS REMOVED. ALWAYS REPLACE TORCH WITH THE PROPER
TORCH MANUFACTURED BY ESAB SINCE IT ALONE CONTAINS ESAB'S
PATENTED SAFETY INTERLOCK.
