Xtrweld 16ST-45 Tapered Contact Tip 0.045 Inch Mig

Product Description

The XTRWELD 16ST-45 is a tapered contact tip designed for MIG welding applications, built to Tweco 16ST series dimensional standards. At 0.373 inches in outer diameter and sized for 0.045-inch wire, this tip fits Tweco-style MIG guns rated from 250A to 600A. It is an OEM-quality replacement consumable intended for professional welders and maintenance technicians who run high-duty-cycle MIG equipment. The part number is marked directly on the tip for fast identification during changeovers, reducing downtime on the wire feeder or gun assembly.

This contact tip is suited for use in Tweco-style MIG gun setups across industrial and fabrication environments. Compatible gun lines include the Classic, Eliminator, Weldskill, Spray Master, Smoke Master, and Supra series Tweco-style platforms rated 250A through 600A. Typical applications include structural fabrication, heavy manufacturing, and maintenance welding where 0.045-inch solid or flux-core wire is the standard consumable. The tapered profile promotes consistent wire guidance and arc stability in high-amperage spray and short-circuit transfer processes.

Installation Notes

Contact tip replacement is performed by qualified welders or maintenance technicians. Always power down the welder and allow the gun to cool before removing a spent tip. Use a tip wrench or appropriate pliers to unthread the old tip and install the replacement snug-tight — do not overtighten, as this can restrict wire feed. Inspect the liner and gas diffuser for wear whenever contact tips are replaced.
