R305-45 - Tregaskiss R305-45 Replacement MIG Gun Neck 300A 45-Degree

Get Back to Welding with the Tregaskiss 300A 45° Neck

When your MIG gun neck gets bent, clogged, or worn out, it directly affects your ability to lay down a good bead. The Tregaskiss R305-45 Gooseneck is the reliable replacement you need to restore your torch's performance. Rated for 300 Amps, this neck is built to handle the heat of day-to-day welding without overheating or failing prematurely. The 45-degree angle is one of the most versatile configurations, giving you the right approach angle for fillet welds, lap joints, and open corners without forcing you into uncomfortable hand positions.

We know that in the shop, equipment takes a beating. That's why this gooseneck features a durable outer shell that resists spatter adhesion and protects the conductive internals from knocks and drops. If you are running a Tregaskiss air-cooled gun, this neck swaps out easily, letting you get back under the hood in minutes. A fresh neck not only fixes physical damage but can also solve feeding issues; a kinked or worn liner inside an old neck often causes wire chatter and burn-backs. Installing a new R305-45 ensures your wire glides smoothly right to the contact tip.

This gooseneck is designed for consistent gas coverage as well. A damaged neck can leak shielding gas or cause turbulence, leading to porosity in your welds. The precision manufacturing of the R305-45 ensures a tight seal and smooth gas flow, keeping your puddles clean. It’s compatible with standard Tregaskiss consumables, so you don't need to buy special tips or nozzles to make it work. Just thread it on, install your liner and consumables, and you are ready to weld.

Whether you are managing a robotic cell or welding manually, having a spare neck on the shelf is smart. Don't let a damaged torch body stop production. Trust the durability of Tregaskiss parts to keep your arc smooth and your downtime low.
