340P121262 - Tweco M8 x 30mm Contact Tip for 0.045" (1.2mm) Wire

Achieve Flawless Welds with Genuine Tweco Contact Tips

Don't let a worn-out contact tip compromise your weld quality. The Tweco M8 x 30 Contact Tip is the professional's choice for reliable, smooth wire feeding and rock-solid arc stability. Designed specifically for 0.045-inch (1.2mm) wire, this premium consumable ensures that your welding machine delivers its full power directly to the workpiece. Whether you are working on automotive repairs, structural steel, or general fabrication, using genuine OEM parts like this Tweco tip is the simplest way to improve your consistency and reduce downtime.

Why does the contact tip matter? It is the final transfer point for the welding current before it creates the arc. A low-quality or ill-fitting tip can cause micro-arcing inside the bore, leading to erratic wire speed and frustrating burn-backs. This Tweco M8 tip features a smooth, precision-drilled bore that guides the wire accurately while maintaining constant electrical contact. The result is a crisp, stable arc that starts easy and stays smooth, allowing you to focus on your puddle control rather than fighting your equipment.

Built to last, the heavy-duty copper construction dissipates heat quickly, preventing the tip from overheating and melting during long welds. This durability means fewer tip changes and more time under the hood. Compatible with ESAB PSF series guns and other torches using the M8x30 standard, this tip is a versatile addition to any welder's toolkit. Keep your shop stocked with fresh tips and experience the difference that quality consumables make in your finished product.
