## Questions & Answers

**Q: Would this rod be ideal for welding a crack in a cast iron kettle?**
A: Probably not. You should use a rod with high nickel content or braze it with a torch. 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. Muggy weld 77 does what it is supposed to. I never thought welding cast iron could be so easy for a novice. So far I have successfully welded 2 antique engine heads and a starting air compressor block all dating from the 1920's. I haven't tried to weld on AC nor DC+, but as suggested DC- it just flows on.

### ⭐ Not for engine blocks!!
*by V***S on April 19, 2025*

They are worthless for welding cast iron engine block!!!

### ⭐⭐⭐⭐ Fixed an old cast iron housing
*by T***T on June 14, 2024*

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.
