The PRO-SOURCE 7498 is a MIG welder contact tip designed for use with 0.052 inch wire outside diameter. The contact tip is the consumable component at the end of a MIG welding gun that guides the electrode wire and transfers welding current to it. Proper tip-to-wire sizing is critical for stable arc performance, consistent wire feeding, and minimizing spatter. At 1.25 inches in length and 0.3 inches in width, this tip is a compact, single-piece consumable suited for standard MIG gun configurations. Welders and fabricators replace contact tips regularly as part of routine gun maintenance to maintain weld quality and prevent feeding issues.
This contact tip is intended for MIG welding applications where 0.052 inch electrode wire is in use. It is appropriate for both shop and field welding environments, including light industrial fabrication, structural work, and maintenance welding. The tip is sold individually but carries a minimum order quantity of 10 units, making it practical for stocking as a consumable supply. It is suitable for installation by professional welders and fabricators performing routine gun maintenance or changeovers between wire diameters.
Designed as a replacement contact tip for MIG welding guns configured to run 0.052 inch diameter electrode wire. Verify thread type and tip seat geometry against your specific gun model before ordering.
Contact tip replacement is performed by welders and fabricators as routine gun maintenance. Always power down the welding machine and allow the gun to cool before replacing the contact tip. Use the appropriate tip wrench or pliers to remove the worn tip and thread in the replacement; do not overtighten, as this can damage the tip seat or diffuser threads. Confirm the replacement tip wire diameter matches the spool wire in use before resuming welding.
