0700300728 - ESAB Narrow Gap Bent Contact Tip 3/16 Inch

Specialized Contact Tip for Narrow Gap Applications

The ESAB 0700300728 is a highly specialized Narrow Gap (NG) Contact Tip engineered for heavy-industrial Submerged Arc Welding (SAW) operations. Designed to accommodate 3/16-inch (4.8mm) diameter welding wires, this component plays a critical role in the successful execution of narrow groove welding procedures. Unlike standard straight tips, this unit features a specific bent profile, which is essential for directing the electrode wire precisely within deep, narrow joint configurations often found in heavy vessel fabrication, power generation, and offshore construction.

Manufactured from a premium high-conductivity copper alloy, the tip is built to withstand the extreme thermal and electrical stresses associated with high-deposition SAW processes. The material composition ensures efficient current transfer from the welding head to the wire, minimizing voltage drop and promoting a stable, consistent arc. The bent geometry allows the welding operator or automated system to position the arc closer to the joint sidewalls, ensuring adequate fusion and preventing lack-of-fusion defects that can occur in restricted access joints.

This contact tip is a genuine ESAB replacement part, ensuring full compatibility with ESAB's Narrow Gap welding heads and torches. Regular inspection and replacement of the contact tip are vital for maintaining weld quality, as a worn bore can lead to erratic wire feeding and arc wandering. By using the correct 0700300728 tip, fabricators can ensure their heavy-duty welding equipment operates at peak performance, delivering high-integrity welds in the most demanding structural applications.
