Bernard 403-20-1.0-25 Mig Welding Contact Tip 1.0mm

Product Description

The BERNARD 403-20-1.0-25 is a MIG welding contact tip designed for use in MIG (GMAW) welding guns. Contact tips serve as the final point of electrical contact between the welding machine and the wire electrode, transferring current to the wire as it feeds through the bore. This tip is sized for 0.045 inch (1.0 mm) wire diameter, making it suitable for a wide range of structural, fabrication, and maintenance welding applications. It is installed and replaced by welders, welding technicians, and fabrication professionals as part of routine gun maintenance.

This contact tip is intended for use in MIG welding setups where 0.045 inch wire is the standard consumable. It fits welding operations in light industrial, fabrication shop, and field maintenance environments. Regular replacement of contact tips is standard practice to maintain arc stability, prevent wire burnback, and ensure consistent weld quality. Each package contains one tip.
