- Pack Quantity: 10 pcs contact tips per pack
- Made in Mainland China
Why Choose CuCrZr Contact Tips?
CuCrZr alloy contact tips outperform standard copper tips in high-amperage and continuous-duty welding scenarios. The chromium and zirconium content significantly increases hardness and resistance to heat deformation, meaning fewer tip changes, less downtime, and more consistent weld quality on every job.
Ideal For
- Professional MIG welders and fabrication shops
- Heavy-duty industrial welding applications
- TR550 torch users looking for OEM-compatible replacement tips
- Both 0.8mm and 1.0mm solid wire applications
Package Contents
- 10 × CuCrZr Contact Tips (choose size: 403-20-30 or 403-20-40)

Frequently Asked Questions
Q: Are these CuCrZr contact tips compatible with the TR550 MIG welding torch?
A: Yes, these contact tips are specifically designed for the TR550 welding torch. The M8 x 8 x 33.5mm double lead thread ensures a precise and secure fit in TR550-compatible torch bodies.
Q: What is the difference between the 403-20-30 and 403-20-40 contact tips?
A: The 403-20-30 is sized for 0.030" (0.8mm) welding wire, while the 403-20-40 is sized for 0.040" (1.0mm) welding wire. Always match the contact tip bore diameter to your wire diameter for optimal arc performance and tip longevity.
Q: How many contact tips come in a pack?
A: Each pack contains 10 pcs of CuCrZr contact tips in your chosen size (403-20-30 or 403-20-40).
Q: Why are CuCrZr tips better than standard copper contact tips?
A: CuCrZr (Chromium Zirconium Copper) alloy offers significantly higher hardness and heat resistance compared to standard electrolytic copper tips. This translates to longer tip life, reduced spatter adherence, and more stable arc performance — especially under high-amperage or continuous-duty welding conditions.
Q: What wire types are compatible with these contact tips?
A: These contact tips are compatible with solid MIG welding wire in the corresponding diameter (0.8mm or 1.0mm). They are suitable for mild steel, stainless steel, and other solid wire applications commonly used with the TR550 torch.
