Circle Cutting Attachment
Permits cutting accurate circles with a manual torch. The attachment
includes a head and radius bar assembly, center-point/adaptor, and dual
swivel castor assembly. Cuts can be made inside or outside the circle.
The torch head is always held vertical during the cutting operation. The
attachment is also handy for maintaining a constant standoff in other
types of cutting.

Plasma cutting uses high voltage. Skin
contact with the torch, the power source,
the workpiece or any grounded object
MUST BE AVOIDED whenever the power
source is ON.
ELECTRIC SHOCK CAN KILL.
1.0 GENERAL
The patented PT-31XLPC is a manual torch with a 75
°
head designed for
use with several Plasma Arc Cutting Packages using clean, dry air as the
plasma gas. The service lines are 25 feet long and the torch is rated to
operate up to 50 amperes at 100% duty cycle for cutting most metals.
Using the PT-31XLPC torch on any power source not equipped with a flow
switch safety interlock may expose operator to unexpected high voltage.
The PT-31XLPC torch is supplied pre-assembled with 30-40 AMP Hi-
Performance XL consumables. Order optional consumables as required
by the specific application.

2.0 INSTALLATION
Before beginning installation and operation with the PT-31XLPC torch, refer
to the safety precautions and operating instructions listed in any of the
following Plasma cutting package instructions.
The PT31XLPC torch comes completely assembled including Front-End
Consumables.
Connect the torch to the cutting power source as shown in Figure 2 below.
Figure 2 shows a typical installation. Consult the cutting power source
instruction manual for more details.
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 elec-
tric shock.
Make sure power switch on the power
source is in the OFF position and pri-
mary input power is deenergized.
SECTION 2 INSTALLATION
3.0 OPERATION
Follow all instructions in the appropriate booklet packed with your Plasma
Cutting package. DO NOT install or attempt to operate this torch without
following these instructions.
SECTION 3 OPERATION
Make sure power switch on the power
source is in the OFF position and pri-
mary input power is deenergized.

Before any maintenance is attempted
on this torch, make sure the POWER
SWITCH on the power source is in the
OFF position and the PRIMARY INPUT
POWER is DEENERGIZED.
Fig 3 - Front End Assembly
The PT-31XLPC torch head contains a
gas flow check valve that acts in con-
junction with the flow switch and cir-
cuitry 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.
4.0 MAINTENANCE
SECTION 4 MAINTENANCE
1. To disassemble the front end, hold the torch with the shield in an upright
position. This will prevent the nozzle, electrode, and swirl baffle from falling
free when the shield is removed. To replace any of these parts, assemble
as shown in Fig. 3.
The gas flow check valve is part of the safety interlock and is permanently
assembled in the torch head. The head must be replaced if this valve
malfunctions. The light spring force used to close the ball check can be felt
by pushing on the electrode when assembling the front end components.
2. Periodically check the heat shield, electrode, nozzle, and swirl baffle.
Replace if worn or damaged.
Do not allow electrode to erode to a length shorter than 5/8 in. as shown
in Fig. 4.
3. Apply a small amount of lubricant P/N 17672 to the heat shield or O-ring
as shown in Fig. 4. Check O-ring for damage whenever the shield is
removed; replace if necessary, P/N 950790.
5. The power cable assembly should be inspected periodically. If there are
any cuts through the protective sheath or if gas leaks are noted, replace the
damaged assembly.

By following steps 1, 2, and 3 in Fig. 5 the power cable can be removed from
the torch. To disassemble the, lay the line out straight, remove the tape from
around the switch lead splices, and free the switch by cutting the leads close
to the splices. (Replacement switches have extra long leads to make up for
any loss due to cutting.) Reassemble in reverse order.
6. To reposition the switch on the torch, slide the flex support back, remove
the tape securing the spliced leads to the power cable, reposition switch,
retape the leads, and pull the flex support back in place. It is not necessary
to cut switch leads.
NOTE: A thin film of silicone lubricant P/N 17672 applied inside of the flex
support will ease the assembly of this part.

WARNING
BE SURE to tighten fittings securely using 2
wrenches during reassembly. (Factory recom-
mended torque is 30 in-lbs). Failure to do so could
result in serious injury to the operator.
Pull flex support back.
