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.

SECTION 4 MAINTENANCE

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.

Remove tape holding

splices.

Slide switch and band from

handle. Snip leads at splice

to replace switch.

Unscrew handle and

power cable from head
