0700300727 - ESAB Narrow Gap Bent Contact Tip 0.045"

Precision Consumables for Advanced Narrow Gap Welding

The ESAB NG Contact Tip 0.045" Bent (SKU: 0700300727) is a highly specialized consumable engineered for the demanding environment of Narrow Gap (NG) welding. Narrow Gap welding is a technique utilized to weld thick materials with a reduced joint angle, significantly lowering the volume of filler metal required and reducing total heat input. However, this process presents unique challenges, particularly regarding sidewall fusion. This contact tip addresses those challenges through its specific bent geometry, designed to mechanically direct the wire—and consequently the arc—towards the joint sidewalls.

Manufactured to ESAB's rigorous standards, this contact tip features a precise 0.045-inch (1.2 mm) bore. The internal tolerance is critical in narrow gap applications where wire cast and helix must be controlled to prevent wandering. The bent design is not merely a feature of the torch neck but is integrated into the tip dynamics to ensure that the arc energy is focused on melting the base material at the edges of the groove, rather than just pooling at the bottom. This is essential for multi-pass welding in heavy industrial fabrication, such as power generation, pressure vessel manufacturing, and heavy structural steel.

Durability is paramount in NG welding due to the confined nature of the groove, which reflects radiant heat back onto the torch front-end parts. The ESAB NG Contact Tip is crafted from a high-conductivity copper alloy that resists softening at elevated temperatures, ensuring a consistent electrical contact point and prolonged service life. By maintaining a stable arc and consistent wire positioning, this component plays a vital role in achieving X-ray quality welds in thick-section materials.

Integrating genuine ESAB consumables into your automated or mechanized welding setup ensures system compatibility and performance reliability. This tip is specifically calibrated for ESAB's Narrow Gap torch configurations, providing the necessary geometry to navigate deep joints without arcing against the sidewalls unintentionally.
