19N48 - ESAB 1/8" (3.2mm) Submerged Arc Contact Tip

Heavy-Duty Performance for Submerged Arc Welding

In the demanding world of heavy industrial fabrication, the integrity of your welding arc is paramount. The ESAB 19N48 Contact Tip is engineered to meet the rigorous standards of Submerged Arc Welding (SAW), a process known for its high deposition rates and deep penetration. Designed specifically for 1/8-inch (3.2mm) welding wire, this contact tip serves as the critical interface between your power source and the filler metal, ensuring that electrical current is transferred efficiently and consistently.

Manufactured from a premium copper alloy, the 19N48 tip is built to withstand the intense heat and high amperage loads typical of SAW applications. Unlike standard MIG tips, which may degrade quickly under continuous heavy load, ESAB's SAW contact tips are formulated to resist annealing and wear. This durability translates directly to operational efficiency; fewer tip changes mean less downtime for your automated systems and more arc-on time for your production line. Whether you are manufacturing pressure vessels, structural steel beams, or large-diameter piping, the reliability of your contact tip can significantly influence the quality of your final weld.

Precision is key in automated welding. The bore of the 19N48 is machined to tight tolerances to provide optimal wire contact without causing excessive drag. This balance ensures that the wire feeds smoothly through the torch head, reducing the risk of bird-nesting or irregular arc lengths. By maintaining a stable electrical contact point, this tip helps prevent micro-arcing within the tube, which can lead to premature failure and voltage fluctuations. For industrial facilities relying on ESAB's renowned A2 and A6 welding heads, using genuine ESAB consumables like the 19N48 ensures that your equipment operates at peak performance specifications.

Investing in high-quality consumables is a strategic decision for any fabrication manager. While the contact tip is a small component relative to the massive machinery involved in submerged arc welding, its role is disproportionately large. A worn or inferior tip can lead to wandering arcs, poor bead profiles, and costly rework. The ESAB 19N48 provides the assurance of OEM quality, delivering the consistency required for code-quality welds in the most challenging industrial environments.
