Optimized Wire-Feeding - 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.
Quick Replacement - Coarse thread speeds contact tip replacement.
Tapered Contact - Tapers lock the contact tip to the diffuser and the diffuser to the neck for excellent electrical conductivity.
Cooling Tail - Contact tip tail is cooled inside the diffuser by shielding gas.
Fewer Parts, More Accuracy - Compatible with Miller MDX-250 MIG Guns and Bernard BTB MIG Guns. Reduces your consumables inventory and the potential for replacement errors.
