9. Mount the Torch Head to the vertical adjustment assembly located on the travel system or fixed stationary
fixture using the mounting hardware supplied with the Torch Head. Further adjustments will be discussed
in the operating section of this manual. See "5.02 Position Torch Head" and "5.03 Insert the Electrode"
on page 5-2.
NOTE
Tuning the mounting position of the Torch Head or adjusting the traveler fixture or carriage system may
be required to achieve best gouging results.
10. Connect the DC power cable(s) to the Torch Head busbar and to the busbar terminal on the back side of the
Control Box labeled “POWER SUPPLY OUT”. These connections must be wrench tight to avoid overheating

and nut supplied for the cable connection on the Torch Head busbar.
11. Return the Control Box Power Supply cover plate to its original position and tighten both screws.
12. Connect the Air Hose Assembly to the Torch Head and to the side of the Control Box labeled “AIR OUT”.
Slide the rubber boot over the connection on the Torch Head.
13. Connect the Torch Head Motor Cable Assembly to the connector on the side of the Control Box labeled
“TORCH HEAD” and the other end to the motor cable connection on the Torch Head. This cable has a 6
pin connector at each end. Refer to "Table 4-7: Cable Identification" on page 4-3.
