TABLE 2 - POWER CABLE REQUIREMENTS
Choose the number and size of secondary power cables on the basis of the combined length
of both the positive (Electrode) and negative (Workpiece/Ground) cables to ensure greatest
efficiency and safe operation in terms of 100% duty cycle. Table 2 presents recommended
selections.
COMPRESSED AIR
Compressed air flows from an air nozzle in the N6000 Torch Head, travels parallel along the
axis of the electrode, and is directed into the molten puddle. The air regulator included in the
N6000 Torch Packages accepts ordinary shop compressed air. Use at least 60 psi input of
compressed air to the regulator. Table 3 shows recommended pressure and volume inputs:

MAIN AIR LINE
Up to the air regulator of the N6000 system, the primary air line may be either rigid or flexible.
The inside diameter of the main air line varies with the length of the line between compressor
and regulator.
LINE LENGTH UP TO 25’ (7.6 m): 1/2” (12.7 mm) INSIDE DIAMETER
LINE LENGTH ABOVE 26’ (7.9 m): 5/8” (15.9 mm) INSIDE DIAMETER
