14T-30 - Tweco Style 14T Series Tapered Contact Tip for .030 Wire

Get Into Tight Spots with Tweco-Style Tapered Tips

Every welder knows the frustration of trying to lay a perfect bead in a tight corner where a bulky MIG gun just won't fit. That's where the 14T-30 Tapered Contact Tip saves the day. Designed as a direct replacement for the Tweco 14T-30 (part number 1140-1301), this tip features a slimmed-down front end that works perfectly with tapered gas nozzles. This design gives you the clearance you need to see your puddle and maintain the correct stick-out, even in the most awkward welding positions.

Built for .030" (0.8mm) wire, these tips are a staple for anyone running Tweco Classic No. 2, 3, or 4 guns or Lincoln Magnum 250-400 series guns. Why pay more for the brand name when you can get the same high-conductivity copper performance for a fraction of the price? These generic replacements are manufactured to strict standards, ensuring the threads lock in tight and the bore is smooth for trouble-free wire feeding. A worn contact tip is the number one cause of erratic arcs and burn-backs; keeping a fresh pack of 14T-30s in your toolbox ensures you are always ready to weld.

Why choose a tapered tip? Standard tips are great for heat management, but they can block your view and prevent the nozzle from getting close enough to the joint in fillet welds. The 14T series solves this by narrowing the profile. This is especially useful for automotive bodywork, exhaust fabrication, and intricate bracket welding. Despite their slimmer shape, they are still rated for heavy-duty use up to 400 amps, making them versatile enough for both light fabrication and heavier structural work.

Don't let a worn-out tip ruin your weld quality. Signs that you need to replace your contact tip include an unstable arc, the wire burning back to the tip, or the hole becoming oval-shaped (keyholing). Swap it out with a reliable 14T-30 and get back to laying smooth, consistent beads. Compatible with standard gas diffusers like the 52 and 54A, these tips are the smart choice for welders who demand performance and value.
