19N46 - ESAB 5/64" SAW Contact Tip (Pack of 5)

Technical Overview of the ESAB 19N46 SAW Contact Tip

The ESAB 19N46 is a specialized contact tip engineered for Submerged Arc Welding (SAW) applications. Designed to accommodate 5/64-inch (2.0mm) welding wires, this component plays a critical role in the electrical transfer efficiency of automated welding systems. It is manufactured to precise tolerances to ensure concentricity and optimal wire-to-wall contact, which is essential for maintaining a stable arc in heavy industrial fabrication environments.

Constructed from a high-grade copper alloy, the 19N46 tip offers superior thermal conductivity and wear resistance. In SAW processes, where amperage loads are significantly higher than in standard MIG welding, the contact tip must withstand intense heat generation without softening or deforming. The material composition of this ESAB tip is selected to resist the abrasive nature of flux and wire while maintaining structural integrity over long duty cycles. This ensures that the voltage drop across the tip-to-wire interface remains minimal, promoting consistent weld penetration and bead geometry.

This contact tip is specifically compatible with ESAB's renowned A2 and A6 automatic welding heads, which are staples in beam fabrication, pipe mills, and pressure vessel manufacturing. The threaded design allows for secure seating within the torch body, preventing loosening due to vibration during operation. Regular replacement of the contact tip is a standard maintenance procedure to prevent keyholing—a condition where the bore becomes oval-shaped—which can lead to erratic arc wandering and poor weld quality. This pack contains five units, providing necessary stock for continuous production lines.

By utilizing genuine ESAB consumables like the 19N46, operators ensure that their equipment performs to factory specifications. The precise bore diameter reduces friction on the wire, minimizing feed motor strain, while the robust construction extends the interval between changeovers, thereby optimizing overall equipment effectiveness (OEE) in high-volume manufacturing settings.
