N800SD1A - Nelson N800i Inverter Stud Welding System 575V

The Smartest Stud Welder in the Shop

If you are looking for a stud welder that practically thinks for itself, the Nelson N800i 575V is the machine you need. Gone are the days of guessing parameters and hoping for the best. This machine features Stud Expert™, a built-in database that lets you select your settings simply by choosing the stud diameter. It’s like having a factory technician built right into the box. If you have specific shop standards, the system can even be re-programmed via a user spreadsheet to match your unique requirements.

Built to Catch Mistakes Before They Happen

We know that downtime and rework are the enemies of profitability. That’s why the N800i comes equipped with advanced "watchdog" features. Have you ever had a weld fail because a cable was loose or the gun was worn out? The N800i’s Cable Monitor™ and Gun Monitor™ detect these issues instantly, alerting you to perform maintenance before you ruin a workpiece. The Cold Plunge Prevention™ feature is a game-changer; if the stud plunge is slowed down—say, by spatter getting stuck between the stud and ferrule—the machine automatically extends the arc time to ensure a solid bond.

Reliability You Can Count On

This isn't just a delicate piece of electronics; it's a workhorse built for the industrial floor. The N800i is backed by an industry-leading 2-year or 1,000,000 weld warranty, giving you peace of mind that your investment is protected. The Chuck Change Indicator is a handy feature that reminds you when to swap out consumables, keeping your gun running smoothly and extending its life. Whether you are welding through rust, scale, or on vertical beams, the N800i adapts to the conditions to deliver a perfect plunge every time.

Ready for Any Job

This 575V pack is designed for heavy industrial power grids, providing the stable current needed for consistent penetration. With integrated gas control options, you are ready to tackle aluminum and galvanized steel without needing external timers or complex rigging. Upgrade your stud welding operations with the Nelson N800i and experience the difference that intelligence and power can make.
