K1297 - Lincoln Electric AC/DC 225/125 Stick Welder 230V

Reliable Power for Maintenance and Fabrication

The Lincoln K1297 AC/DC 225/125 Arc Welder is a heavy-duty stick welding power source designed for professionals and serious hobbyists who demand flexibility and performance. Operating on standard 230V single-phase power, this machine delivers a substantial output range of 40-225 amps on AC and 30-125 amps on DC. This dual-output capability allows operators to select the optimal current type for their specific application, electrode type, and material thickness.

Technically, the K1297 is engineered for safety and longevity. It is NEMA rated, UL listed, and CSA approved, meeting stringent industry standards for electrical safety (60 Hz models). The unit is fan-cooled, providing extra thermal protection to internal components during extended use, ensuring a long service life even in demanding shop environments. The 225-amp AC output is sufficient for running 3/16" (4.8 mm) diameter general-purpose mild steel electrodes, making it capable of welding heavy plate steel. The 125-amp DC output is perfect for most 1/8" (3.2 mm) electrodes, offering the arc stability required for critical root passes or thin-wall tubing.

Installation is straightforward as the unit comes pre-wired with an input power cable and plug. The package also includes a complete welding accessory kit, featuring an insulated electrode holder, a heavy-duty work clamp, and their respective cables. The intuitive front panel features an electrode selection chart, providing a quick reference guide for amperage settings based on electrode type and diameter. For workshops requiring a dependable, low-maintenance machine that covers the spectrum of stick welding needs, the Lincoln AC/DC 225/125 is the industry standard.
