N7500 SYSTEM
The N7500 System produces in a single pass uniform “U” or “J” grooves of various depths up to 1-1/8” (28.6
mm). Two or more passes produce grooves of greater depth. Through continuous control of arc voltage or amper-
age and a constant travel speed, the groove is held within 0.025” (0.635 mm) target depth. Victor Arcair Jointed
Jetrods ® Electrodes, with tapered male and female ends, make it possible to produce grooves of unlimited length.
Control elements and circuitry for the N7500 System are housed in a Control Box and a splash-proof Pendant.
Gouging operations are managed remotely using the Remote Pendant with a multi-function LCD display and touch
pad controls.
Groove depth and width are controlled in two ways:
• By changing the travel carriage’s forward speed or by changing the work piece rotational speed.
• By changing the electrode’s diameter and increasing or decreasing amperage.
NOTE
Remote Pendant is NOT submersible.
This manual has been structured to provide the user with all the information required for assembly, operation and
troubleshooting of the N7500 System. Illustrations, charts and other supporting data are provided to bridge the
gap between theory and practice.
In addition, the N7500 System can be integrated with any mechanized travel system that provides forward travel
over a steel plate while in the flat, vertical, or over-head positions. The N7500 Torch Head can also be mounted
in a stationary position for work on rotating shafts, round steel, or a vessel. In a stationary set up the work-piece
rotates in a counter-clockwise direction and the Torch Head is generally located at the work-piece’s 4 o’clock position.
