77 Electrode: Non-Cracking Cast Iron Welding Rod
$65.00 – $650.00
77 is a premium cast iron welding rod that produces welds which are high strength, crack resistant, and porosity free when applied to a wide variety of cast irons. The special tri-metal core wire has a high current carrying capacity and the specially designed coating converts the impurities of the base metal into slag instead of being trapped in the deposit. The high deposition rate creates an extremely narrow heat affected zone– a feature suitable for all weldable cast irons requiring post weld machining.
77 cast iron welding electrodes are softer than nickel rods, and have unique properties that allow the cast iron welds to stretch and elongate up to 300 percent more than other rods, which helps prevent the base metal and weld from cracking in the process.
- High efficiency weld metal transfer eliminates electrode overheating
- Crack-resistant formula eliminates the need for pre-heating or special cooling
- Ideal for heavy machinery, trucking, bus lines, automotive, marine, and RVs
- Repair cast iron exhaust manifolds, engine blocks, industrial machines and more
Note: Guide the electrode at a steep angle, keeping the arc length short. Use short staggered.
