Tweco Style 14H-30 Heavy Duty MIG Contact Tip for .030 Wire

Reliable Performance for Your MIG Torch

Every welder knows that the contact tip is the heart of the MIG gun. If your tip is worn, ovaled, or clogged with spatter, your arc stability suffers, leading to frustrating starts and sloppy welds. The Tweco Style 14H-30 Heavy Duty Contact Tip is built to keep you welding smoothly. Designed specifically for .030" (0.8mm) wire, this tip features a heavy-duty wall thickness that stands up to the intense heat of long welds better than standard light-duty tips. Whether you are running a Lincoln Magnum 250 in a garage or a Tweco #4 on a production line, this tip delivers the consistent current transfer you need for a buttery-smooth arc.

Compatibility is key in a busy shop. This 14H-30 tip is the "universal soldier" of MIG consumables, fitting a massive range of guns including the Tweco Classic No. 2, 3, and 4, the Spray Master series, and the widely used Lincoln Magnum 300 and 400 guns. It screws easily into standard gas diffusers like the 35-50, 52, or 54A. The 1/4-28 threads are precision cut to prevent cross-threading and ensure a tight electrical connection, minimizing resistance and heat buildup at the diffuser junction.

Don't let a cheap, worn-out tip ruin your bead. By upgrading to these heavy-duty 14H series tips, you reduce the frequency of tip changes and downtime. The precise bore ensures the wire slides through with just the right amount of contact, reducing micro-arcing inside the tip which causes premature failure. Stock up on these essentials to ensure your machine is always ready to lay down perfect welds on mild steel, stainless, or aluminum projects.
