42.0300.0462 - Fronius Style TIG Ceramic Gas Cup Size 6 (3/8")

Keep Your Arc Smooth with the Right Fronius Cup

Every TIG welder knows that a cracked or clogged cup is a recipe for disaster. If you are running a Fronius rig, you expect precision, and that starts with your consumables. The Fronius Nozzle Cup #6 (Part 42.0300.0462) is the standard go-to size for general purpose TIG work. With a 3/8-inch opening, it gives you a great balance of gas coverage and puddle visibility, allowing you to get into tight corners without losing your shield.

This isn't just a generic piece of ceramic; it's built to thread smoothly onto your Fronius torch and stay put. The high-quality material stands up to the heat of the arc without crumbling or cracking prematurely, saving you trips to the tool crib. Whether you are walking the cup on pipe or dabbing filler on a bench, having a fresh, clean nozzle ensures your gas flows smoothly over the puddle, keeping your welds bright and shiny.

Don't let a $5 part ruin a $500 weld. Keep a few of these #6 cups in your kit. They are easy to swap out and essential for maintaining that buttery smooth arc Fronius is famous for. Perfect for everything from mild steel brackets to critical stainless joints, this cup helps you lay down beads you can be proud of.
