71023145 - Arcair N7500 Automated Gouging System with Gullco Tractor

Precision Automated Gouging for Heavy Industry

The Arcair N7500 Gouging System with Gullco 220 VAC Travel Carriage represents the pinnacle of automated metal removal technology. Designed for heavy-duty industrial applications such as shipbuilding, pressure vessel manufacturing, and bridge construction, this system takes the variability out of the gouging process. Unlike manual operations where operator fatigue can lead to inconsistent groove depths and widths, the N7500 delivers machine-like precision hour after hour. The system utilizes the air carbon-arc process to melt metal and blast it away with a high-velocity air stream, but it does so with automated feed controls that maintain the perfect arc length and travel speed.

At the heart of this package is the integration with the Gullco Travel Carriage. Running on a 220 VAC supply, this tractor unit carries the gouging head along a track (sold separately or standard Gullco track), ensuring a perfectly straight line of travel. This is critical for preparing long weld seams or back-gouging root passes on large structures. The automated carriage eliminates the "start-stop" irregularities common in manual work, resulting in a clean, U-groove profile that requires minimal secondary grinding before re-welding.

The system includes a remote pendant control, placing the power in the operator's hands while keeping them at a safe distance from the intense heat, noise, and fumes generated during the gouging process. This significantly improves workplace safety and operator comfort. The N7500 head is capable of handling jointed gouging electrodes ranging from 5/16-inch to 3/4-inch, making it versatile enough for various plate thicknesses and groove requirements. By automating the feed of the electrode and the movement of the torch, the Arcair N7500 can achieve metal removal rates up to five times faster than manual methods, drastically reducing project timelines and labor costs.

Installation is straightforward for facilities equipped with standard high-amperage DC welding power sources and compressed air lines. The rugged design of both the Arcair head and the Gullco carriage ensures reliability even in the harshest fabrication environments. Whether you are removing defects, preparing plate edges, or back-gouging welds, this system provides the consistency and speed required for modern high-throughput manufacturing.
