Every welder knows that the contact tip is the heart of the MIG gun. It’s the final point of contact where the welding current is transferred to the wire, and if it’s worn out or clogged, your entire weld suffers. These Tweco-style 11-30 contact tips are designed to keep your machine running smoothly and your beads looking sharp. Whether you are running a classic Tweco No. 1 gun or the popular Lincoln Magnum 100L found on machines like the MIG-Pak, Weld-Pak, or SP-series, these tips are the perfect fit for your .030" (0.8mm) wire setup.
Burnback, ovaling, and keyholing are common issues that plague contact tips, especially during long welding sessions. These tips are built from durable copper alloy to resist the intense heat of the arc and maintain their shape longer. The bore is precision-drilled to ensure your .030" wire slides through with just the right amount of contact—tight enough for a good electrical connection, but loose enough to prevent bird-nesting at the drive rolls. If you’ve been struggling with an erratic arc or stuttering wire feed, a fresh contact tip is often the cheapest and fastest fix.
This 25-pack is ideal for the serious fabricator or the busy shop. Contact tips are consumables, and they go fast. Having a bulk pack in your toolbox means you never have to stop a job to run to the supply store. They thread easily into standard 35-50 gas diffusers, locking in tight for a secure connection. The side of each tip is clearly marked "11-30," so you won't accidentally grab the wrong size when you're in a hurry. Rated for up to 200 amps, these tips handle the full range of short-circuit and spray transfer welding that your 200A-class machine can dish out. Upgrade your consumables and keep your arc steady with these professional-grade replacements.
