Pro-source 7490 Mig Welder Contact Tip 0.045 Inch Wire Od

Product Description

The PRO-SOURCE 7490 is a MIG welder contact tip designed for use with 0.045-inch wire outside diameter. The contact tip is the terminal point through which welding wire feeds and receives electrical current, making consistent tip condition critical to stable arc performance and weld quality. This tip fits standard MIG and flux-core welding guns and is replaced routinely during production welding, maintenance welding, and fabrication work. At 0.026 pounds and a compact 1.25-inch length, it is a lightweight consumable part that welders and maintenance technicians keep on hand in quantity.

This contact tip is suited for MIG welding applications in industrial, commercial, and shop environments where 0.045-inch solid or flux-core wire is the standard consumable. Typical install scenarios include structural fabrication, pipe welding, and general metal fabrication where operators run higher-amperage processes that consume tips at a faster rate. The minimum order quantity is 10 units, making it practical to stock as a bench consumable rather than a single-replacement part.

Key Features

• Designed for 0.045-inch wire outside diameter, both minimum and maximum rated at 0.045 inches
• Compact form factor: 1.25 inches in length, 0.3 inches in width and depth
• Lightweight at 0.026 pounds for easy handling and rapid tip changes
• Sold individually per package with a minimum order quantity of 10 units
• Direct replacement consumable for standard MIG welding gun tip seats

Compatibility

Designed as an OEM-style replacement contact tip for MIG welding guns that accept standard tips and use 0.045-inch diameter welding wire.

Installation Notes

Contact tips are installed and serviced by welders and maintenance technicians using standard tip wrenches or pliers. Always power down the welding machine and release wire tension before changing a contact tip. Allow the gun nozzle and tip to cool before handling, as both reach high temperatures during operation. Inspect the tip seat and diffuser for spatter buildup when replacing the tip to ensure a clean electrical connection.
