14H-35 Heavy Duty Contact Tip (.035") - Tweco Style Replacement

Reliable Performance for Heavy-Duty MIG Welding

When you are in the middle of a long weld, the last thing you want is a contact tip that overheats or fuses to the wire. The 14H-35 Heavy Duty Contact Tip is built to handle the heat. Designed as a direct replacement for the popular Tweco 1140-1202, this tip is the workhorse of the 14 series. It is specifically crafted for welders running .035" wire who need a tip that lasts longer and performs better than standard light-duty alternatives.

What sets the 14H series apart is its heavy-duty construction. Made from robust copper alloy, these tips have thicker walls that help dissipate heat more effectively, allowing you to weld at up to 400 amps without compromising performance. This means fewer tip changes, less downtime, and a smoother, more stable arc for your welds. The threaded design ensures the tip locks firmly into your gas diffuser, providing a solid electrical connection that you can trust.

Identification is made simple with the part number and wire size stamped directly onto the side of each tip, so you never have to guess if you grabbed the right size from your toolbox. Whether you are using a classic Tweco gun, a Lincoln Magnum, or a compatible Radnor setup, the 14H-35 drops right in. It is an essential consumable for fabrication shops, automotive repair, and general industrial maintenance where reliability and arc stability are non-negotiable.
