I use it not only for welding, brazing, and soldering, but also for a broad range of usages requiring controlled heat. I have even occasionally used it to reheat my coffee on cold days when I am working out of doors.
The rusty mechanism on the table next to it on the old wagon is part of a very vintage McCormick Reaper (the one in the history books) that I am restoring. It is a crucial part, since it contains the shaft that rotates the arms that sweep the grain into the cutter and then onto the ground, and all sorts of pivoting parts that allow the arms to move up and down as they swing. The reaper is probably 130 years old, and has spent a good bit of that time outside, so when I acquired it the shaft had rusted quite firmly to the castings in which they turn. I soaked the whole mess first in penetrating oil, then in old diesel oil, and even in used brake fluid, but the parts remained rusted together. So I used the ultimate answer in such cases, which is to heat the castings red hot with my torch. Since heat weakens rust and expands holes, the rust gave up with the result that the shaft now rotates happily and the arms go through their motion. One of many uses for my tank set .
The tank set qualifies as a very good product according to the criteria in my Good Products Bad Products book. Costs are low for the capability it gives me, and it has never failed to do what I want it to do. It is easy to use and fits me well, is nicely made, and fills me with positive emotions, ranging from nostalgia to an instant sense of accomplishment whenever I use it. It is elegant in its simplicity, and lets me mingle with the welding culture. Environment? One generally uses a so-called neutral flame (no particulates) with this device, I am stingy in my use of acetylene, and I don’t use it that often. It certainly is not in the league of my furnace, water heater, or gas stove.
Also it is fun to weld. It never ceases to amaze me how easy to turn two pieces of metal into one with a simple flame. I must admit I generally use electrical equipment to weld these days, since it is fast, more easily controlled, and allows one to avoid oxidation by using an inert gas. But welding with a gas flame strikes me as a somehow purer experience. It's just me and the fire!
