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.
Steel is an alloy composed of iron and carbon—the higher the carbon content, the stronger, harder and more brittle the steel. There are many types of steel that can be used for steel welding jobs, all of which are categorized based upon various physical properties and carbon content. High carbon steel is very strong and it is used for files, cold chisels and various metal tools while low carbon steel is used for tubing, nails and castings.
Before you start welding steel, you will have to first determine the weldability of the metal. This is inversely proportional to its ability to be hardened by heat. Basically, this means that varieties of the metal with fewer alloying agents can easily be welded better than others.
Next, measure the equivalent carbon content of the different alloys of steel. This compares the properties of any steel alloy to those found in ordinary carbon steel. If possible, use only high strength, low-alloy metals specifically designed for welding steel.
Most jobs require only a hand held propane torch. Super Alloy 1 is recommended when heat or aesthetics is an issue. Otherwise we recommend our SSF-6 Silver Solder for torch welding: with a holding strength of 71,000 PSI, SSF-6 is as strong as a MIG or TIG weld, with a beautiful finish.
Steel repair on stainless steel can be very difficult; it is difficult to cut and is prone to distortion because of its high thermal expansion. Control the amount of ferrite in the weld to minimize hot cracking, preheat, and use steel welding and solder products such as Super Alloy 1, SSF-6, and SSQ-6 when working on different types of stainless steel.

Square steel is joined to rectangular steel with SSF-6 and an oxyacetylene torch. SSF-6 provides a perfect color match and better finish than MIG welding, with a bond of over 70,000 PSI.
At 56% silver, SSF-6 Silver Solder is ideal for brazing all types of steel. This video gives step by step instructions for repairing steel pipe with an oxy-acetylene torch.
Rich Shoop (The Gun Slinger, Mt. Ayr, Indiana) was hired to restore this antique Ithaca, and discovered a missing piece on the barrel.
2 galvanized steel plates are joined using Super Alloy 1 and a propane torch. The low melting point of Super Alloy 1 is ideal for soldering without damaging the protective zinc coating.
Soldering Galvanized Steel with Super Alloy 1
Josh Colson from Auburn Muffler and Auto Repair in Auburn, Washington, is using SSF-6 Silver Solder by MuggyWeld.com, to braze a cast iron flange to aluminized steel tubing for better air flow.
SSF-6 brazes a stainless steel tube to a steel plate at over 70,000 PSI with a propane torch.
Joining square steel tubing to mild flat bar steel with SSF-6 Silver Solder. Straight propane is used for this braze, as SSF-6 is lower temperature than most high content silver solders.
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.

Super Alloy 1 multi metal solder joins aluminum to galvanized steel at 350 degrees--a bonding strength of 20,000 psi.
Solder zinc plated steel to brass tubing or pipe with Super Alloy 1 low temperature solder. This multi-metal solder melts at 350 degrees and bonds at 20,000 psi.

Auto body panels are very thin nowadays, and mig welding these parts without warpage can be very difficult.
This clip shows a fender being repaired with Super Alloy 1 and COOL BLUE Heat Paste.
SSQ-6 is the perfect solution for jobs like this--parts are balancing, and if a rod were used they could easily be knocked over but the silver solder almost glues them together and acts like a jig when heated.
Muggy Weld SSF-6 silver solder has been used in almost every type of maintenance shop in situations where high strength and a perfect finish is desired. SSF-6 is a flux-coated high grade alloy (56% silver) and cadmium free.

In this "How to Tech" we molded tail light housings end pieces out of Pot Metal onto the rear end part of a quarter panel. We did this by using Muggy Weld, LLC who has been supplying industry professionals with high quality maintenance welding alloys and electrodes that are not sold at your neighborhood welding supply store for over 25 years.
This hydraulic hose unit would cost over $300 to replace -- IF you could even find the part. John at Mobile Hose & Spray Systems made the repair quickly and easily with our SSF-6 Silver Solder.
Occasionally an application arises where it is necessary to join aluminum to steel. Most welders will tell you this can't be done, because they haven't used our Super Alloy 1 solder.
