K113-2 - Lincoln Electric K113-2 600A Handheld SAW Gun, 15 ft, 3/32 in

Lincoln Electric K113-2 600A Submerged Arc Welding Gun Overview

The Lincoln Electric K113-2 is a heavy-duty, handheld submerged arc welding (SAW) gun designed to bring the high-deposition benefits of the SAW process to applications requiring manual control. Rated at a substantial 600 Amps, this gun is engineered for industrial environments where durability, reliability, and performance are paramount. The K113-2 comes factory-ready to feed 3/32-inch (2.4 mm) diameter solid wire, making it an excellent choice for structural steel, shipbuilding, and heavy fabrication tasks where deep penetration and high weld quality are required.

Submerged arc welding is traditionally associated with fully mechanized beam-mounted systems or tractors. However, the K113-2 bridges the gap, allowing operators to perform semi-automatic welding with the flexibility of a handheld tool. This is particularly useful for short welds, curved seams, or areas where a mechanized carriage cannot easily access. The gun features a 15-foot (4.5 meter) cable assembly, providing ample reach around large workpieces without the need to constantly reposition the wire feeder or power source.

Robust Design for Industrial Use

Lincoln Electric has built the K113 series with a focus on longevity. The gun features a simple, compact design that minimizes the number of moving parts, thereby reducing the likelihood of mechanical failure in harsh shop environments. The robust construction withstands the heat and physical wear typical of high-amperage welding. Maintenance is straightforward, allowing operators to quickly replace contact tips or liners and get back to work, minimizing downtime.

Why Choose Lincoln Electric SAW Guns?

Lincoln Electric is a global leader in arc welding solutions, and their submerged arc equipment is the industry standard for reliability. The K113-2 exemplifies this legacy. Unlike lighter-duty MIG guns adapted for flux use, this gun is purpose-built for the granular flux and high heat of the SAW process. The concentric flux cone design ensures that the flux flows evenly around the wire, providing optimal coverage regardless of the gun angle, within reason. This attention to detail results in fewer weld defects and less rework.

Technical Specifications and Compatibility

The K113-2 is rated for 600 amps at a high duty cycle, suitable for continuous welding operations. It is designed to work with Lincoln's range of submerged arc wire feeders, such as the LT-7 or other compatible power feed units. The 3/32" wire size is a sweet spot for manual SAW, offering a balance between deposition rate and puddle control. For shops handling multiple wire sizes, the K113 platform is versatile; while this specific SKU (K113-2) is set up for 3/32", the gun body is durable enough to handle the demands of various heavy-industrial tasks.
