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

Genuine ESAB 19N48 Contact Tip for 1/8" Wire

The ESAB 19N48 Contact Tip is a specialized consumable designed for professional Submerged Arc Welding (SAW). Sized for 1/8" (3.2mm) wire, this tip is a standard replacement part for ESAB's widely used A2 and A6 automatic welding heads. When your welding setup demands high amperage and continuous duty cycles, the quality of your contact tip defines the stability of your arc. This genuine ESAB part is crafted to deliver superior electrical conductivity and thermal management, ensuring that your welding parameters remain constant throughout long runs.

Technical Superiority and Fitment

Submerged arc welding involves currents that often exceed the capabilities of manual processes, placing immense stress on the contact tip. The 19N48 is constructed from a robust copper alloy that resists the erosive effects of the moving wire and the extreme heat of the arc zone. The 1/8" bore is precision-drilled to ensure maximum surface contact with the wire, which is essential for efficient current transfer. Poor contact can cause voltage drops and resistive heating at the tip, leading to wire burn-back or fusion inside the tip. ESAB's engineering minimizes these risks, providing a smooth, reliable feed path.

Maintenance and Performance

Regular inspection and replacement of contact tips are vital for maintaining weld quality. As the bore of a contact tip wears into an oval shape, the electrical contact point shifts, causing the arc to wander. This can result in lack of fusion or inconsistent bead width. By replacing worn tips with the ESAB 19N48, you restore the precise alignment and electrical characteristics of your torch. This tip is designed for quick change-outs, featuring a standard thread that seats securely into the torch body or extension tube, ensuring excellent conductivity across the joint interface.

This product is ideal for welders and operators working in shipyards, pipe mills, and heavy fabrication shops where ESAB automation is the standard. It supports the high deposition rates that SAW is famous for, handling the thermal load without softening or deforming. When you choose the 19N48, you are choosing a component that matches the performance specifications of your ESAB power source and wire feeder, guaranteeing that your setup runs as smoothly as the day it was installed.
