42.0001.4751 - Fronius Contact Tip 1.2mm (0.045") M8 Thread - Pack of 10

Keep Your Fronius Torch Running Smoothly

Every welder knows that the contact tip is the smallest part of the gun but causes the biggest headaches when it fails. If you are running a Fronius MIG gun, you need consumables that match the quality of the machine. The Fronius 42.0001.4751 Contact Tip is the standard 1.2mm (0.045") replacement for your M8 threaded setups. These aren't just generic copper tubes; they are built to handle the heat and abuse of daily fabrication work without fusing to your wire halfway through a bead.

Why does the M8 thread matter? It's all about heat and current. The beefier M8 thread grabs onto the diffuser tighter and has more metal-to-metal contact than smaller tips. This means the heat generated at the arc doesn't get trapped in the tip—it dissipates back into the gun. For you, this means the tip stays harder for longer, the hole stays round, and you aren't stopping every hour to unstick a wire. When the tip stays cool, the current transfer is smooth, giving you that crisp, frying-bacon sound you want, rather than the sputtering of a worn-out contact point.

This package comes with 10 tips, which is the industry standard for a reason. Contact tips are consumables; they wear out. Having a fresh pack in your toolbox or locker means you aren't scrambling when you start seeing keyholing or experiencing burnback. Whether you are welding mild steel or stainless, these tips provide the consistent wire feed you need to lay down good beads. Don't let a cheap or worn-out tip ruin a critical weld or cause downtime on the line.

Installation is straightforward—just unscrew the old one and thread this in. Make sure it's snug to ensure good electrical connection, but don't over-torque it. Pair these with your standard Fronius nozzles and gas diffusers to keep your gas coverage laminar and your spatter low. Stick with genuine parts to keep your Fronius rig welding like a Fronius.
