OVERVIEW

Keep Your Fronius Torch in Top Condition

Welders know that a smooth, consistent arc depends on the condition of the torch's front-end consumables. The Fronius Insulator Ring (420.1001.4295) is a small but mighty part that keeps your MIG gun functioning correctly. Located inside the nozzle assembly, this ring acts as a barrier, preventing the welding current from traveling where it shouldn't. If you've ever experienced erratic arcs or unexpected shorts while maneuvering into tight corners, a cracked or missing insulator ring could be the culprit.

Designed for the popular Fronius AL and AW series torches, this replacement part is a direct fit for models like the AL 3000, AL 4000, and AW 5000. Over time, heat and spatter buildup can cause the original insulator to become brittle or coated in conductive debris. Swapping it out is a quick and easy maintenance task that restores the safety and efficiency of your gun. With this convenient pack of 5, you can keep spares in your toolbox or supply cabinet, ensuring you're never stuck waiting for a part in the middle of a job.

Don't compromise on quality when it comes to your equipment. Using genuine Fronius replacement parts guarantees that your torch maintains its original performance specifications. These rings are built to handle the heat, resisting cracking better than generic alternatives. Protect your investment and ensure your welds remain clean and defect-free by replacing worn insulators as part of your regular torch maintenance routine.

Why Choose Genuine Parts?

  • Perfect Fit: No rattling or loose nozzles; snaps perfectly into place.
  • Durability: Stands up to the heat of high-amperage welding.
  • Value: The 5-pack ensures you have backups when you need them most.

FAQ

The insulator ring electrically isolates the gas nozzle from the live parts of the torch neck, preventing short circuits and protecting the torch body.

It is compatible with various Fronius Multilock torches, including the AL 2300, AL 3000, AL 4000, AW 2500, AW 4000, and AW 5000 series.

This product is sold as a pack of 5 insulator rings.

The ring measures approximately 15mm x 8mm (0.59" x 0.31").

Replace the ring if it shows signs of cracking, heat damage, or if it is heavily coated in spatter that cannot be removed, as this can cause electrical shorts.

Yes, this is a genuine OEM Fronius part, number 420.1001.4295.

Yes, it fits specific water-cooled models like the AW 4000 and AW 5000, as well as gas-cooled models.

Indirectly, yes. A damaged insulator can misalign the nozzle or allow gas turbulence, so a good insulator helps maintain proper shielding gas flow.
