11401220 - Tweco 11-52 Contact Tip, 0.052 in (1.3 mm) - 25 Pack

Reliable Arc Starts with Tweco 11-52 Tips

Every welder knows that the contact tip is the last point of contact between your machine and the weld puddle, making it one of the most important small parts in your setup. The Tweco 11-52 (Part Number 1140-1220) is the standard replacement tip for welders running 0.052" (1.3mm) wire through Tweco No. 1 or Mini-MIG guns. Whether you are laying down heavy flux-cored beads or running solid wire for structural work, having a fresh, high-quality tip is the easiest way to fix an erratic arc.

Worn-out tips are a major cause of frustration in the shop. As the wire feeds through, it eventually wears the hole into an oval shape, causing the wire to wander and the arc to stutter. These genuine Tweco tips are built from durable copper alloy to resist that wear longer than generic alternatives. They provide a snug, consistent electrical connection to the wire, which means less spatter, better heat control, and a smoother feeling under the hood. If you are experiencing "stuttering" or the wire feels like it's dragging, swapping in a new 11-52 tip is often the instant fix.

Designed for easy change-outs, these tips feature standard threading that screws right into your gas diffuser. They are compact, economical, and essential to keep in your toolbox or welding cart. Using the correct size tip for your wire is non-negotiable; the 0.052" size is specifically machined to handle the heavier gauge wires often used in fabrication and repair. Don't let a cheap or worn-out consumable ruin your weld appearance or integrity.

When you stick with the 11 Series from Tweco, you are using a product that has been an industry staple for decades. They are trusted by professionals for their consistency. Whether you are working on automotive repairs, light fabrication, or farm equipment, keeping a stock of these tips ensures you aren't shut down by a simple burnback or feeding issue. Keep your gun running cool and your arc running hot with fresh copper at the business end of your torch.
