ADAPTOR KIT

PT-15XL TORCH TO HYPERTHERM PLASMA SYSTEM

P/N 17517

This kit permits connecting a plasma arc cutting torch to a

Hypertherm plasma arc system. The standard PT-15XL torch

(P/N 20762) may be used, but the service lines and sleeve

(or barrel) supplied with the torch is not used. A basic PT-

15XL torch that is supplied without service lines and sleeve is

available under P/N 16365, and made particularly for use with

this kit for connecting to a Hypertherm system.

These torches sre supplied with a nozzle assembly for 400

amps, N

cutting. See Form F-15-031-B, "Instructions for PT-

15XL Plasma Arc Cutting Torch", which is packed with each

torch, and select the desired nozzle assembly. Also, read

and follow the installation instructions of the nozzle assembly

covered in Form F-15-031-B.

This adaptor kit (P/N 17517) containes the following compo-

nents:

1 — Adaptor, Water Injection ................................ P/N 17501

1 — Adaptor, Water-In .......................................... P/N 17503

1 — Adaptor, Water-Out ....................................... P/N 17504

A nozzle retaining cup (20793) without feet is available which

may work better with some Hypertherm installations.

INSTALLATION

Before installing the adaptor kit, make sure that all input

power to the system is deenergized (OFF).

If using the standard PT-15XL torch (20762), refer to Form F-

15-031-B, and remove the following components.

1. Remove clamp (996565) and boot hose (996647).

2. Unscrew sleeve (19483) and slide it back along with the

bushing (996342) far enough to clear the service line

connections.

3. Disconnect the service lines, and remove them (including

the pilot arc cable) from torch.

You are now left with the basic torch assembly like P/N 16365.

To assemble the kit to the basic torch assembly (16365), pro-

ceed as follows (see Fig. 1 and Form F-15-031-B):

1. Connect the two 4-in. long adaptors (17503) and (17504) to

the short "watrer-in" and "water-out" fittings on the torch

body. Note that the "water-in" connection has left-hand

threads. Tighten the connecting nuts firmly with a wrench.

2. Connect the short adaptor (17501) to the long "Water-

Injection" fitting on the torch body. Tighten the connection

firmly with a wrench.

3. Thread the hoses nad cables from the Hyperthern system

through the torch sleeve and then connect them to the

proper torch and adaptor fittings on the torch body. Tighten

all connections firmly using two wrenches.

INSULATOR - 20409

4. Cut the end of the Hypertherm pilot arc cable and strip

the insulation off 1/2" of wire.

5. Slide the high freq. (HF) connection insulator (P/N

20409) over the stripped wire and insert the wire into

the H.F. connector (P/N 20408). Tighten the setscrew.

6. Slide the HF connection insulator back over the HF

connector and secure with vinyl tape.

7. Assemble the sleeve to the torch body.

8. Install the desired nozzle assembly as directed in

Form F-15-031-B.

See Table 1 and 2 for operating data.

1. When cutting plates up to 1-in. thick under water, cutting speed and cut surface appearance are not appreciably affected.

Therefore, the above data given for cutting plates up to 1-in. thick are suitable for both normal and underwater cutting.

2. Cut quality and cutting speed diminish when cutting from 1 to 3 in. thick materials underwater, particulary aluminum. The 0.230

in. nozzle assembly (P/N 2075613) is not recommended for cutting aluminum underwater; however, the 0.200 in. nozzle

assembly can be used for cutting up to 3 in. thick aluminum and still obtain a reasonable appearing cut. The approximate cutting

speeds for underwater cutting of materials from 1 to 3 in. thick are given in Table 2 (current, pressure, flow, and standoff settings

of eash nozzle are the same as given above in Table 1, except where noted).

*Cutting speeds given are average. They may vary depending on material composition, surface conditions, etc. Practice cuts in

scrap area of new materials are recommended before starting cuts on production work.
