Pro-source 14H-45 Mig Welder Contact Tip 0.045 in Wire Dia

Product Description

The PRO-SOURCE 14H-45 is a MIG welder contact tip designed for use with 0.045 inch wire diameter. The contact tip is the consumable component at the end of the MIG gun that guides the welding wire and transfers current to it at the point of arc initiation. Proper tip sizing to wire diameter is critical for stable arc performance, consistent wire feed, and minimizing spatter. This tip measures 1.48 inches in length and 0.28 inches in width, and weighs 0.024 pounds. It is a direct replacement consumable intended for routine service on MIG welding equipment.

This contact tip is suited for MIG welding applications requiring 0.045 inch wire, a common size used in structural, fabrication, and heavy sheet metal work across industrial and shop environments. Welders and maintenance technicians replace contact tips regularly as part of scheduled gun maintenance to maintain weld quality and prevent wire burnback. The 0.045 inch bore sizing accommodates the full range of standard 0.045 inch solid and flux-core wire commonly used in production and repair welding.

Installation Notes

Contact tip replacement is performed by qualified welders or maintenance technicians as a routine consumable swap. Always power down the welder and allow the gun to cool before removing a spent tip. Use the appropriate tip wrench to avoid damaging the diffuser threads. Inspect the gas diffuser and nozzle for spatter buildup whenever a tip is changed.
