Material Options Explained
-
- Copper (Standard): Ideal for general welding tasks with solid arc transfer
- CrZr (Chrome Zirconium): Offers higher wear resistance, perfect for robotic/high-frequency jobs
- CuAg (Power Silver): Enhances current transfer and resists heat degradation for longer tip life
How to Choose
-
- Use U4167H05 for standard 1.2 mm welding with stable performance.
- Choose U4167H12 or H13 for long-life performance in automation or high-speed lines.
- Pick U4167H04 when extreme reach is needed in tight access applications.
- Go with U4167H11 for larger diameter wire (e.g. heavy welding with 1.4 mm).
