948835 - Tweco 16S Style Heavy Duty Contact Tip 1/16" (5-Pack)

Technical Overview of the ESAB 948835 Contact Tip

The ESAB 948835 is a high-performance contact tip designed for industrial MIG welding applications requiring the use of 1/16-inch (1.6mm) electrode wire. Belonging to the widely utilized 16S series, this consumable is engineered to fit standard Tweco-style MIG guns, providing a critical interface for electrical current transfer to the welding wire. The "HD" designation indicates a Heavy Duty classification, suggesting a robust wall thickness and superior copper alloy composition intended to withstand elevated temperatures and high-amperage duty cycles common in heavy fabrication environments.

Precision manufacturing ensures that the internal bore tolerance is tightly controlled. This minimizes friction while maintaining optimal electrical contact with the wire, a key factor in preventing micro-arcing inside the tip which can lead to premature failure or burn-back. The threaded base ensures a mechanical and electrical bond with the gas diffuser, facilitating efficient heat transfer away from the arc zone. By maintaining a stable arc and consistent wire feeding, this contact tip supports high-quality weld deposition and reduces the frequency of consumable replacement.

This product is supplied in a bagged quantity of five, making it a convenient stock item for maintenance and repair operations. It is compatible with a broad range of air-cooled and water-cooled MIG guns that utilize the 16S series consumable platform. The copper alloy material is selected for its balance of hardness and electrical conductivity, ensuring that the tip retains its geometry even under thermal stress.
