Rockmount Jupiter AAA Welding Electrode: 1/8" Dia., For Cast Iron and Steel To Cast Repairs - 1 lb

Jupiter AAA is engineered for high-strength, ductile welds on all grades of cast iron, including Meehanite, ductile, malleable, and gray cast irons, as well as steel to cast iron. With up to 70,000 PSI strength, it eliminates electrode overheating, ensuring smooth, machinable deposits that are free from porosity. The result is more efficient, high-quality repairs with excellent tie-in between passes. Ideal for large cast iron repairs, Jupiter AAA offers superior performance on dirty or oil-soaked pieces without overheating issues. It's the perfect choice for joining cast iron to steel, delivering reliable, cost-effective results with smooth, durable welds. Application: Remove cracks and stop drill Use medium arc and stringer beads. Skip weld, light peening recommended. For critical or heavy parts preheat to 500°F (260°C). Cool slowly after welding
