Bernard 7491 Mig Welder Contact Tip 1/16 Inch Wire Od

Product Description

The BERNARD 7491 is a contact tip designed for MIG welding applications, specifically engineered for use with Bernard Q Gun MIG welders. The tip accepts wire with a maximum outside diameter of 1/16 inch (1.60 mm) and serves as the final point of electrical contact between the welding machine and the consumable wire electrode. It transfers welding current to the wire as it feeds through, directly affecting arc stability and weld quality. This tip is a consumable component that requires periodic replacement as part of routine MIG gun maintenance. Installation is performed by welding technicians and maintenance professionals working in fabrication, manufacturing, and field welding environments.

This contact tip is suited for MIG welding setups that run 1/16 inch wire, commonly used in heavier-duty welding passes where higher deposition rates are needed. It is a direct-fit component for Bernard Q Gun torches. Typical install scenarios include production welding lines, structural fabrication shops, and maintenance welding operations where Bernard Q Gun equipment is in regular service. The tip is sold individually, making it straightforward to replace single worn or damaged tips without purchasing in bulk.

Compatibility

Designed for use with Bernard Q Gun MIG welders, compatible with 1/16 inch wire outside diameter electrode wire.

Installation Notes

Contact tips are installed and replaced by welders or maintenance technicians. Always power down the welding machine and allow the gun to cool before removing a worn tip. Tips are typically threaded into the gun nozzle assembly and should be hand-tightened or tightened with an appropriate tip wrench — do not overtighten, as this can damage the gun neck threads. Inspect the tip bore for wear or spatter buildup regularly, as a worn or clogged tip will cause erratic arc behavior and wire feeding issues.
