Review: Works as advertised and more. - An extremely easy rod to use. Muggy weld 77 does what it is supposed to. I never thought welding cast iron could be so easy for a novice.

Review: Fixed an old cast iron housing - Rod works good but isn't cheap. You get 4 rods for $65 but fixing a cracked transmission housing was worth it. Watch some videos before attempting unless you've done this before. ## Features - Contains: 14 rods 3/32 inch diameter, 12 inch length - 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 ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Muggy Weld | | Item Weight | 1 pounds | | Product Dimensions | 15 x 2 x 2 inches | | Is Discontinued By Manufacturer | No | | Size | 1/2 lb 3/32 diameter | | Material | Metal | | Item Package Quantity | 1 | | Batteries Included? | No | | Batteries Required? | No | ## Images ![77 Cast Iron Welding Rod Kit 1/2 lb (3/32" diameter) - Image 1](https://m.media-amazon.com/images/I/51wlj6xmfDL.jpg) ## Available Options This product comes in different **Material Type, Size** options. ## Questions & Answers **Q: Would this rod be ideal for welding a crack in a cast iron kettle?** A: Probably not.

It is important to have the entire pot quite hot before welding and cool it very slowly when finished. **Q: Can i use it in exhaust pipe ?** A: No. The SSF-6 brazing rod will work on the steel exhaust pipe. **Q: Is this an ac or dc rod?** A: Both AC and DC Reverse **Q: How should the 77 rods be stored? Are they as sensitive to moisture as 7018?** A: All welding rods are sensitive to moisture. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works as advertised and more. *by D***. on May 8, 2019* An extremely easy rod to use.
