Description
🔧 ERCuSi-A MIG Wire 0.8mm – 15kg Spool for Silicon Bronze Welding
The ERCuSi-A MIG wire (0.8mm diameter) is a premium-grade silicon bronze welding wire designed for joining copper, brass, and galvanized steels. Supplied on a 15kg spool, this wire is ideal for MIG welding in applications where excellent corrosion resistance, electrical conductivity, and clean appearance are important.
Formulated with copper and around 3% silicon, this alloy provides excellent puddle control and low fume emission. It creates smooth, attractive welds with minimal spatter—especially useful in projects where aesthetics and conductivity are both priorities.
💪 Applications of ERCuSi-A MIG Wire
The ERCuSi-A MIG wire is used across a wide range of industries including HVAC, automotive, marine, and general fabrication. Common uses include:
-
Welding galvanized steel components
-
Repairing copper and bronze castings
-
Automotive panel and exhaust work
-
Artistic and architectural metal fabrication
-
Electrical equipment where low resistance is required
This wire is also suitable for surfacing steel to improve corrosion resistance. It provides strong metallurgical bonding with minimal cracking risk.
⚙️ Welding Characteristics and Tips
The ERCuSi-A wire performs best when used with pure Argon shielding gas. It offers a stable arc with minimal spatter and smooth bead formation, even on thin metals. Recommended current for 0.8mm diameter typically ranges from 80 to 130 A, depending on the base material and welding position.
Ensure workpieces are clean and free of oxide layers for the best results. For full setup and amperage guidelines, refer to our welding parameters guide.
