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 PT27 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.
