SECTION 6:
N7500 SYSTEM USES
6.01 SYSTEM USES
This section briefly describes some uses for the N7500 System. If you have any questions concerning a specific
application for this system contact Victor Technologies Technical Services Department at 800-426-1888 or 940-
566-2000.
GOUGING NON-FERROUS METALS
The N7500 System can be connected to DC Straight Polarity (DCEN) to gouge non-ferrous metals, such as nickel,
copper alloys, etc. “Figure 6-1: N7500 DC Straight Polarity (DCEN)” shows the proper connections for the system
to run on DC Straight Polarity.

NOTE
Use standard #12 insulated copper wire as your signal wire. It must be long enough to prevent stress
on the Contactor connection.
6.02 Zero Force Rough Machining
The N7500 system can work with an automated travel system to remove hardsurfacing material from steel mill
rolls; kiln rolls and shafts which needs re-working. Remove as much as 1-1/2” (3.81 cm) of old material from the
outside diameter in a single pass and as little as 1/8” (3.18 cm) for the finish pass.
OSCILLATION GOUGING TO REMOVE MATERIAL
The N7500 can be mounted on a welding oscillator to remove material. Normal uses for an oscillated gouge would
be to remove cladded material from plates requiring a beveled edge and to remove backup bars and excessive
weld crowns.
