MIG gun consumables principally comprise of the front-end part of the gun, the nozzle, retaining head, contact tip and the liner. These components are responsible for properly feeding the welding wire and for establishing the electrical conductivity necessary to create the arc.
While the welding power source you use undoubtedly influences your welding quality, so too can your consumables. In fact, MIG gun consumables are one of the most neglected areas of the welding operation. Without proper installation, storage and maintenance, these components can cause significant downtime for changeover and needlessly add to inventory cost.
