INSTALLATION
Slowly apply pressure to the gas lines. Check for leaks at all connections before continuing. If there
are no leaks, shut off the gas supplies and continue with installation.
7. Connect the pilot lead to the Torch Head. Press the two ends of the connector firmly together. Thread the
plastic lead cover/connector onto the mating Torch Head connector.
8. Press the Torch Head Assembly upward to connect to the Mounting Tube. Pull the leads back as needed
to ensure a proper fit through the Mounting Tube and Torch Leads End Cap. Hold the Torch Head Assembly
stationary; rotate the Mounting Tube to thread it onto the Torch Head.
CAUTION
Ensure that the leads do not twist within the mounting tube. Leads must lie as shown in the installation sketch.
9. The lower end of the Mounting Tube includes four threaded holes. Install an Allen set screw in any of the
threaded holes to secure the Torch Head Assembly to the Mounting Tube.
10. Install the appropriate consumable parts as shown on the following pages. The torch manual includes
diagrams showing the correct parts to install, depending on the metal to be cut and the gases in use.

WARNINGS
Do not install consumables into the Cartridge
while the Cartridge is attached to the Torch Head.
Keep foreign materials out of the consumables and Cartridge.
Handle all parts carefully to avoid damage,
which may affect torch performance.
1. Check the appropriate cut chart for the right combination of parts for the cutting application.
2. Stack the consumable parts together.
3. Insert the stack of consumable parts into the cartridge. Ensure that the large O-ring on the torch tip fits
completely into the cartridge. If any part of the O-ring protrudes from the cartridge, the parts are not seated
properly.
4. Use the removal tool to hold the cartridge assembly, while turning the shield cup onto the cartridge
assembly. When this group is fully assembled, the shield should protrude from the front of the shield
cup 0.063" to 0.083" (1.6 - 2.1 mm). Without this protrusion the shield cup is not properly tightened
onto the cartridge assembly.
5. Take the removal tool off the cartridge. Fit the cartridge assembly onto the torch head. The cartridge
should seal to the large O-ring on the torch body as shown. If the cartridge does not seal on the O-ring, the
cartridge is not fully tightened.
