E. "Over Temperature" LED (Yellow light) - will turn
on if the machine becomes overheated and will turn
off automatically after the machine cools down if the
on/off switch is still on.
"Low Air Flow" LED (Green light) - will turn on
during operation when the air flow is set correctly the
LED will switch off below 15psi (1 bar).
On/Off Switch LED (Green light) - will light when
power supply is switched on and power is applied.
LED will turn off when switch is in OFF position.
Air Pressure Gauge (Side Panel) - Shows air
pressure in bars and psi.
3.3 ASSEMBLING PT-31XL
COMSUMABLE PARTS
Make sure power switch on power source is in OFF
position and primary input power is deenergized.
Install the electrode, baffle, nozzle, and heat shield as
shown in Fig. 3-2. Tighten heat shield snugly but do not
overtighten.
BE SURE to install the swirl baffle in the torch. Failure
to do so would allow the nozzle (tip) to contact the
electrode. This contact would permit high voltage to
be applied to the nozzle. Your contact with the nozzle
or workpiece could then result in serious injury or
death by electric shock.

The PT-31XL torch head contains a gas flow check
valve that acts in conjunction with the flow switch
and 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 PAT-
ENTED SAFETY INTERLOCK.

3.4 CUTTING WITH THE PT-31XL

Wear the usual protective gloves, clothing, and hel-
met. Helmet with filter lens shade No. 6 or 7 should
provide adequate protection for your eyes.
Never touch any parts forward of the torch handle
(tip, heat shield, electrode, etc.) unless the power
switch is in the OFF position.
CAUTION: Do not depress the torch switch unless the
torch nozzle is touching the workpiece or
within 0.02" (0.51mm) of workpiece.
