3.2 GENERAL

Make sure power switch on console is in the "OFF"

position and primary input power is deenergized.

3.3 ASSEMBLY

Install PT-32EH front end parts as shown in Figure 3-

The torch head contains a gas flow check valve and a nozzle back pressure tap that

act 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.

SECTION 3 INSTALLATION

The valve pin is a crucial member of the system. Its func-

tion is to open the gas flow check valve that is permanently

assembled within the torch head. If the pin is not correctly

placed in the electrode, the valve will not open and the sys-

tem will not function. The valve pin also improves electrode

cooling by increasing the velocity of air over the inner surface

of the electrode.
