I worked as a heavy equipment mechanic until retirement, no longer have access to professional equipment and am unwilling to spend that kind of money on occasional welding repairs. I've only used these rods a couple of times and they work well, you should consider them for brazing or brazing rods, not real welding rods. Use proper cleaning techniques, heat control, and allow work to cool properly before disturbing it. These "soldering sticks" have worked great for me with a MAP gas torch, ensuring the job is hot enough to melt the stick and not melt the stick flame.
