The Arcair-Matic N7500 gouging system delivers high productivity for any metal fabrication operation where gouging and welding represents a large portion of the work schedule.
The Arcair-Matic® N7500 Gouging System adds new dimensions of flexibility and control in modern weld preparation. It’s the most advanced air carbon-arc gouging/grooving system in the world. The N7500 System assures improved productivity in the following ways:
Higher yields of optimum quality end product
Dramatic reductions of man-hours and process cost
Expanded areas of applicability
Remote Pendant providing complete control of the gouging operation where it needs to be .... in the welder/operator hands.
All functions from determining gouge parameters, start/stop function, travel delay, and the capability to manually feed or retract the electrode in the Torch Head. The welder/operator can view the amperage and voltage during gouging sequence easily while maintaining the electrode on the weld seam that’s being back gouged.
A single electrode contact shoe assembly accepts the entire range of Arcair® gouging electrodes from 5/16” (7.9 mm) through 3/4” (19.1 mm). The N7500 Torch Head eliminates the necessity of stocking or changing contact shoe assemblies when changing electrode sizes.
The gouging system uses the Power Supply “contactor” to ensure that the gouging current is only present when the welder/operator presses the “start” button on the Remote Pendant.
System is easily connected to the various power supplies available in the industry.
Ensures conformity to pre-determined, pre-selected groove depth and width specifications.
Welder/Operator can use the “Parameter Guide” option on the Remote Pendant to view the recommended amperage and travel speed once the electrode and gouge depth is chosen.
A unique “travel delay” function assures excellent groove geometry at the very beginning of the groove. This function eliminates a sloped groove at the beginning of the gouge, eliminating the need for a starting pad.
No current detect and low voltage functions shut down the system when these conditions are sensed. These functions ensure optimum groove quality and prevent damage to the equipment and work.
Redesigned Torch Head with extended front end to give the welder/operator better range of viewing during the gouging operation ensuring the electrode is maintained in the correct position to the weld seam.
