OT: wood stoves

Installing a low vent entrance will cause a negitive draw to the inside of the combustion room thus filling the room with smoke gas.

The wood stove smoke will be heavy in CO so that puts you and your family at extreme risk for death.

About the best place to get current vent install info is from your local building code dept or fire dept. There's not one piece of code that you can skimp on as they protect your installation form killing your family.

If I were in your situation I think I'd put some effort into trying to learn to like a different stove. What you're talking about doing is going to be a lot of work even if everything turns out to be in your favor. Even if the pipe is secured in place only at the top of the chimney and where it stubs out for the stove connection you're going to have to remove and replace mortar up top and bricks and mortar in the room. After that, how do you plan to lift it? I'm not suggesting that it can't be done. It could even be an enjoyable job in a horrible sort of way. It's just that if you aren't absolutely forced to deal with a particular stove that won't fit, you could easily find one that would and use your time and effort to better advantage in something with a more attractive payback. The satisfaction of stubbornly doing everything your own way is fairly cold comfort when you find yourself close to retirement age and you don't have enough put aside to stop working. Guess how I know.

All the best, Stan

I assume you're referring to a "stick" welder, since it's not practical to add cable to a TIG or MIG welder. Stick welders are considered to constant current sources; that is regardless of the load, the output current will be constant. (The same is true of TIG welders, while MIG welders are considered to be constant voltage sources.) This brings up a valid question: "Why do I need crank up the current on the welder when I add cable, if it's supposed to be a constant current source?" The answer is that the welder is not a true constant current source. If it was, the stinger would start arcing all around the room as soon as you turned on the welder, because a true constant current source would put out a bazillion volts or whatever was required to start the arc going. Actually, the welder is neither a true constant voltage nor a true constant current source. When you add cable, you effectively change the output impedance of the welder, which requires you to adjust the current setting to get the same current as before.

I could go into further detail, but it's really not necessary. The main point is that from an electrical point of view, it doesn't matter if you put the small cable at the stinger end or the welder end of the cable. You will get the same current and voltage at the stinger in either case.

I burn with a wood stove and I'm familiar with installations using Duravent (or similar) multi-walled flue pipe, but I'm not getting a picture of what you're describing. Is the 'casing' inside a masonry chimney? I especially don't get the welded T part.
Need more info.
