11601106 - Tweco 16S-116 Standard Contact Tip for 1/16 Wire (25 Pack)

Precision Engineering for Heavy-Duty Welding

The Tweco 16S-116 Contact Tip is a critical component designed for industrial MIG welding applications requiring 1/16-inch (1.6mm) wire. As part of the renowned Tweco 16 Series, this consumable is engineered to deliver optimal electrical conductivity and thermal management. In high-amperage welding environments, the interface between the contact tip and the welding wire is the primary point of current transfer. Tweco OEM tips are manufactured from high-grade copper alloys that minimize electrical resistance, thereby reducing heat generation at the contact point (I²R losses) and preventing premature failure due to overheating or keyholing.

The 16S-116 features a standard outside diameter and a heavy-duty 3/8"-24 thread, making it compatible with Tweco 52 and 54 series gas diffusers commonly found in Spray Master and other heavy-duty MIG guns. The internal bore is precision-drilled and swaged to strict tolerances, ensuring a consistent electrical contact patch with the wire while allowing for smooth feeding without drag. This balance is essential for maintaining a stable arc voltage and preventing micro-arcing inside the tip, which is a common cause of burnback and erratic weld beads.

For industrial operators, utilizing genuine Tweco consumables ensures compatibility and reliability. The 16S-116 is designed to withstand the rigors of high-deposition welding, including flux-cored and solid wire applications. Its robust construction resists spatter adhesion and deformation, maintaining the integrity of the gas shielding envelope. By adhering to OEM specifications, these contact tips help maintain the calibrated parameters of your welding system, ensuring that the set voltage and wire feed speed translate accurately to the workpiece.
