Assembling Pt-31Xl Consumable Parts; Cutting With The Pt-31Xl - ESAB PCM-500i Instruction Manual

SECTION 3
E. Fault Light. Will glow amber under the following
conditions and operations will come to a complete
stop.
Flow Fault: The fault light will be mostly on but
will flick off for about 1/10th of a second every
second. This indicates that the air flow supply is
low.
Over Temperature: The fault light will be mostly
off but will flick on for about 1/10th of a second
every second. This indicates that the duty cycle
has been exceeded. Allow the power source to
cool down before returning to operate.
High/Low Line Voltage: The fault light will rap-
idly blink on and off (five times per second). This
indicates that the input voltage is outside the "+ or
-" 15% range of the input rating.
Over-Current: The fault light will be on continu-
ously. This indicates that input current has been
exceeded.
All fault signals will remain on for a minimum
of 10 seconds. If fault clears, all will reset
automatically except for over-current. To clear
over-current, the power must be shut off for 5
seconds and then turned back on.
3.3 ASSEMBLING PT-31XL COMSUMABLE
PARTS
Make sure power switch on power source is in OFF
position and primary input power is deenergized.
To assemble "XT" consumables, remove the seat
supplied with the torch. Insert the plunger into the head.
(The plunger is reversible.) Then reassemble the seat
firmly with a wrench. Install the electrode, baffle, nozzle,
and heat shield as shown in Fig. 3-2. Tighten heat shield
snugly but do not overtighten.

NOTE: If cutting at less than 20 amps, standard
consumables illustrated below in Figure 3-2A
are recommended. These consumables are
supplied in Spare Parts Kit, P/N 19676. Air
presssure should be set at 40 to 50 psig.

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 hield is removed. ALWAYS REPLACE
TORCH WITH THE PROPER TORCH MANUFAC-
TURED BY ESAB SINCE IT ALONE CONTAINS
ESAB'S PATENTED SAFETY INTERLOCK.
For additional torch information, see booklet (F-14-246)
packed with the PT-31XL torch.

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.
