37500 - UTP Nickel 99 Cast Iron Stick Electrode 3/32" (2.4mm) - 10lb Pack

Reliable Solutions for Cracked Cast Iron

Don't let a cracked engine block or broken machine part stop your project. The UTP Nickel 99 Stick Electrode is your go-to solution for welding cast iron with confidence. Designed with a 99% pure nickel core, this 3/32" (2.4mm) rod is formulated to produce a weld that is soft enough to be machined, drilled, or tapped. This is crucial for repairs where the part needs to be returned to its original dimensions and functionality. Unlike steel rods that create hard, brittle welds on cast iron, Nickel 99 fuses seamlessly with the base metal, creating a ductile bond that resists cracking during cooling.

Welders appreciate the UTP Nickel 99 for its forgiving arc characteristics. It strikes easily and maintains a steady arc on both AC and DC polarity, making it compatible with most stick welding machines, from industrial buzz boxes to portable inverters. The 2.4mm diameter is perfect for "cold welding" techniques—short beads and peening—which help prevent the cast iron from overheating and cracking. It is excellent for filling holes, fixing casting flaws, and joining cast iron to mild steel. The flux coating is designed to burn clean, minimizing the chance of porosity and ensuring a professional-looking bead.

This 10lb (4.54 kg) package ensures you have ample supply for larger jobs or ongoing maintenance needs. Whether you are fixing an antique stove, a transmission housing, or a heavy-duty industrial pump, UTP Nickel 99 gives you the best chance of a successful, leak-proof repair. Its versatility in all welding positions (flat, horizontal, vertical, and overhead) means you can perform repairs in-situ without dismantling heavy machinery. Trust in the quality of UTP consumables to turn a difficult cast iron repair into a routine job.
