Contact tip is aligned and centered with the liner lock when the diffuser is tightened creating a flawless wire-feed path. Reduces burnbacks, bird-nesting and erratic arc.
Replace and trim liners accurately every time - no measuring required! Liners are loaded and locked from the front of the gun, then locked and trimmed flush with the power pin cap at the back. Reduces wire-feeding issues associated with improper liner trim lengths.
