OVERVIEW

Reliable Sumig .045" Contact Tips (10-Pack)

Keep your Sumig 477 MIG gun running smoothly with these genuine replacement contact tips (Part # 0900.1754). Designed for .045" (1.2mm) wire, these tips are built to handle the rigors of professional welding. The secret to their longevity lies in their material: CuCrZr (Copper Chromium Zirconium). This premium alloy is significantly harder and more heat-resistant than standard copper tips, meaning they won't melt back or deform as quickly when things get hot.

Whether you are fabricating structural steel, working on heavy machinery, or running a busy repair shop, changing contact tips frequently is a hassle that eats into your productivity. These heavy-duty tips resist wear and erosion, providing a consistent electrical connection for a smooth, stable arc hour after hour. They are a direct fit for Sumig 477 series guns, ensuring a tight, secure connection to the gas diffuser for optimal gas coverage and current transfer.

Sold in a convenient pack of 10, these contact tips are an essential stock item for any welder using Sumig equipment. Don't let a worn-out tip ruin your weld quality or cause wire burn-back; upgrade to CuCrZr tips and experience the difference in durability and performance.

FAQ

CuCrZr (Copper Chromium Zirconium) is a harder alloy that withstands higher temperatures without softening. This results in a longer lifespan and better arc stability compared to standard E-Cu copper tips, especially in high-heat applications.

This contact tip is designed for 0.045" (1.2mm) welding wire.

No, this specific part number (0900.1754) is designed for the Sumig 477 series MIG guns. Please check your gun's manual or parts breakdown to confirm compatibility.

These contact tips are sold in packs of 10.

While you can use CuCrZr tips for aluminum, aluminum wire often expands more than steel. Ensure the bore size is appropriate for the specific grade of aluminum wire you are running to prevent feeding issues.

The contact tip transfers the welding current to the wire. If the material softens due to heat, the hole wears out (keyholes), leading to poor contact, erratic arcs, and potential burn-back.
