16S-35 - Tweco 16S-35 Heavy-Duty Contact Tip .035 (25-Pack)

Premium Tweco 16S-35 Contact Tips for Industrial MIG Welding

The Tweco 16S-35 Contact Tip (Part Number 1160-1102) represents the industry standard for heavy-duty MIG welding consumables. Designed for professional fabrication environments, these contact tips are engineered to handle high-amperage applications, rated for use up to 600 amperes. Each tip is precision-machined from high-quality copper alloy tubing, a material choice that ensures optimal electrical conductivity and thermal transfer. This construction is critical for maintaining arc stability and preventing premature tip failure during prolonged welding sessions.

One of the defining characteristics of the 16S series is the rigorous manufacturing tolerance. Tweco holds the inside diameter (ID) tolerance to +/- .003 inches. This precision ensures that the welding wire feeds through the tip with minimal friction while maintaining sufficient electrical contact for a stable arc. The interior surface is machined to be consistent and smooth, significantly reducing the likelihood of micro-arcing inside the tip, which can lead to burn-backs and erratic feeding. The threaded base design allows for a secure mechanical connection to the gas diffuser, ensuring maximum current transfer from the gun to the wire.

Inventory management and setup verification are simplified thanks to clear identification markings. Each 16S-35 tip is stamped with its part number and the compatible wire diameter (.035"), allowing operators to quickly verify they are using the correct consumable for their wire size. This 25-pack configuration provides excellent value for high-volume shops, ensuring that welders have a ready supply of fresh tips to maintain production quality. Whether used in automated systems or manual heavy-duty MIG guns, these genuine Tweco consumables deliver the reliability and performance required for industrial metalworking.

Technical Specifications and Compatibility

These contact tips are designed to fit standard Tweco MIG guns and compatible systems utilizing the 16S series form factor. They are specifically sized for .035-inch (0.9 mm) solid or flux-cored welding wires. The robust copper alloy material withstands the intense heat of high-amperage welding, making them suitable for structural steel, heavy equipment manufacturing, and general fabrication tasks where duty cycles are demanding.
