B. Connect XT-301 Torch Head to XT-301 Torch Leads

NOTE

Handle the torch head carefully to avoid damage. The installer may choose
to follow Section 3.07, Installing Consumable Parts, before installing the
torch head. This will provide additional protection to the coolant tube on
the torch head during installation.

1. Install the torch clamp assembly included in this kit, in place of the pinion removed previously.

2. Slide the end cap up onto the torch leads.

3. Remove and discard the protective end caps from the Mounting Tube.

4. Install the O-ring included in this kit in the groove at the upper end of the Mounting Tube.

5. Slide the positioning tube up onto the torch leads, far enough to allow access to the lead connection fittings.

6. Connect the XT-301 torch head to the Maximizer leads as shown.
