OVERVIEW

Long-Lasting Performance for Heavy-Duty Welding

The Sumig 0900.1830 Contact Tip S+ CuCrZr 1/16" is a premium consumable engineered for professional welders who demand reliability and longevity. Designed specifically for the Sumig Gun 477, this contact tip is manufactured from high-grade Copper Chromium Zirconium (CuCrZr). Unlike standard electrolytic copper (E-Cu) tips, this advanced alloy is formulated to withstand the extreme thermal stresses of high-amperage welding without softening or deforming prematurely.

In heavy industrial environments, downtime caused by frequent consumable changes can significantly impact productivity. The CuCrZr material used in this Sumig tip maintains its hardness at elevated temperatures, resisting the common "keyholing" or ovalization of the wire bore that leads to erratic arcs and poor weld quality. This makes it an excellent choice for continuous welding operations, automated systems, or any application utilizing 1/16" (1.6mm) wire where stability is paramount.

Precision manufacturing ensures that the 0900.1830 tip provides optimal electrical contact with the welding wire. A stable electrical connection is critical for smooth wire feeding and consistent arc characteristics. By choosing genuine Sumig consumables or high-quality OEM equivalents like this S+ series tip, you ensure that your Sumig 477 gun operates at peak efficiency, delivering clean, high-quality welds shift after shift.

Key Benefits

  • Extended Lifespan: CuCrZr alloy lasts significantly longer than standard copper tips.
  • Thermal Stability: Resists annealing and deformation under high heat.
  • Precision Fit: Engineered specifically for the Sumig 477 MIG gun platform.
  • Stable Arc: Maintains bore integrity for consistent current transfer.

FAQ

This tip is made from CuCrZr (Copper Chromium Zirconium), which is harder and more heat-resistant than standard E-Cu (Electrolytic Copper), allowing it to last longer in high-heat applications.

This contact tip is designed for use with 1/16" (1.6mm) welding wire.

It is specifically designed for the Sumig Gun 477 series.

CuCrZr resists softening at high temperatures, preventing the bore from wearing out (keyholing) quickly, which ensures a stable arc for longer periods.

Replace the tip when the bore becomes oval-shaped (keyholed), causing the arc to wander, or if the wire frequently burns back to the tip.

The SKU 0900.1830 corresponds to a Sumig part number, typically indicating a genuine or direct-replacement OEM-spec component.

While CuCrZr tips can be used for aluminum, they are often sized slightly differently for thermal expansion. Always check if a specific aluminum-designated tip is recommended for your application, though 1/16" is a common aluminum wire size.
