14H-xx Silver Contact Tips for Tweco #2/#3/#4 MIG Gun - 25 Pack

Silver Coated Ultra Duty Tweco Contact Tips

Ultra duty Tweco style 14 series 14H-35Z(Silver) and 14H-45Z(Silver) silver coated contact tips. Superior conductivity, extreme life.

These Tweco 14H-xx contact tips are made from Chrome Zirconium (CuCrZr) at their core which is 2-4x harder than standard Copper (E-Cu) making it significantly more resistant to mechanical wear. The additional silver coating greatly enhances conductivity and increases heat dissipation. That means smoother current flow, less heat buildup, and slower wear — so the tip lasts longer and gives more consistent welding performance.

If you use Tweco OEM 14H-35 or 14H-45 contact tips, are sick of paying so much per tip, but can't find anything else that keeps up on quality, this is the tip for you. No matter how good the machining is, a copper tip will never keep up with a silver tip!
