Lincoln AC225 Stick Welder

Product Overview

The Lincoln AC225 Stick Welder stands as one of the most trusted and recognizable machines in arc welding, widely known as “The Time-Tested Original.” Decades of dependable performance have made it a benchmark for reliability, consistency, and ease of use in stick welding. Designed to deliver a smooth, stable AC arc, the AC225 simplifies challenging welds across a broad range of materials, including carbon steel, low-alloy steel, stainless steel, and cast iron. Its proven versatility makes it an excellent choice for maintenance departments, repair shops, farms, home workshops, and light fabrication environments where straightforward operation and consistent results are essential.

Built with simplicity and performance in mind, the AC225 features an intuitive 40–225 amp selector switch that allows quick and precise current adjustments without complicated setup. This user-friendly design supports welders of all experience levels, from beginners to seasoned professionals. The machine’s smooth arc performance ensures reliable results with a wide variety of electrodes, including mild steel, low-hydrogen, stainless steel, and hardfacing rods. With a powerful 225-amp AC output, it easily handles common electrode sizes up to 3/16 in. (4.8 mm) for general-purpose welding and 5/32 in. (4.0 mm) for specialty applications, making it a versatile, all-in-one solution for everyday welding tasks.

Practical design elements further enhance the AC225’s value in real-world applications. An attached 6-ft (1.8 m) input power cable with an integrated NEMA 6-50P plug allows fast connection to standard 230V single-phase power, minimizing setup time and getting you welding quickly. Its compact footprint balances portability with stability, fitting comfortably in space-limited workshops while remaining rugged enough for demanding use. Backed by recognized safety certifications—including NEMA rating, UL listing, and UL/CSA approval the Lincoln AC225 provides confidence in both performance and compliance. Together, these features continue to make the AC225 the go-to entry-level professional stick welder and a lasting standard for maintenance, repair, and light fabrication work.
