Mike, I have to tell you that your 77 cast iron electrodes are fantastic--I need to order more to have it on hand.
I just welded a small block Chevy 400 engine with a broken ear on the starter mount. The engine was sitting on a 3 wheel engine stand and fell over breaking the mount. I placed a mild steel bolt in the broken mounting hole and built the whole corner back up, then I removed the bolt and re-tapped the bolt hole with no problem. It's looking pretty good.
I work on hard to find and restore irreplaceable antique cast iron parts. Your 77 welding rods are better than anything I've tried in the past. I'll try to remember to send you photos of my next cast iron job.
Applications that require strength and a perfect finish would do well with the SSF-6 silver solder from Muggy Weld. Unlike fluxless rods, our 56% silver soldering rod has the highest silver content on the market, has high thin flow, flows easily, and can be used with a variety of metals at over 70,000 psi.
Before SSF-6, soldering was considered a tricky and challenging undertaking. Several problems can arise during the process; the solder can melt to a ball or refuse to flow, or in some instances, joints fail to completely fill in with the solder or the metal melts before the solder does.
These problems can all be prevented using the SSF-6 soldering rod. It is the only flux-coated silver solder that's strong enough to clean oxidized stainless steel, therefore eliminating the need for washing or cleaning the metal before soldering. Also, SSF-6 wets even burned stainless and 1" of material flows 18". It can be used on cast iron, as well as for bonding stainless steel, brass, copper, bronze, mild steel, tool steel, carbon steel, and chrome-moly individually or with other metals. To ensure safe use for medical and pharmaceutical applications, our product is also cadmium-free.

SSF-6 Silver Solder brazes stainless steel to copper, brass, or steel... in any combination, and can be successfully applied using a propane torch, oxyacetylene, MAPP gas or a natural gas torch.
How to braze brass tubing to stainless steel tubing with a high strength silver solder at 1150 degrees and only using a propane torch.
Joining a brass plate to a stainless steel plate at 1150 degrees with no warpage of the parent metal. A propane torch is used to heat both the brass and stainless evenly before adding the flux.
We are using SSF-6 Silver Solder to join two stainless steel plates together at 1150 degrees. The braze was made with a very small amount of silver solder, it doesn't need much as the alloy is over 70,000 psi. A propane torch was the gas used in this video and the solder is flux coated.
