Worth noting that soapstone is available for use as a marking tool. I've used it in blacksmithing for making chalk-lines on iron. Actual chalk won't survive the forge, soapstone will remain visible.

So it doesn't look like a souls one, but you can get some and make a white soapstone sign anywhere you please

Can you post a picture?

You could try some UV curable solder mask like this. I haven't tried that specific product though, so I don't know how strong it will be. You could just add kapton tape on top of the curable solder mask to be safe.

will these work?

These are copper covered steel welding rods. You should probably be able to solder them without issues. I've only used copper-covered MIG wire, which is much thinner, and it soldered OK.

Nothing to show yet, but I managed to braze some wire coat hangers together pretty easily using flux coated welding rod and the 0-size tip that came with the Victor kit. Had to be pretty quick to avoid burning through, and my brazing rod is way too big (1/8") but it's definitely possible and the brazing connection was very strong. Certainly good enough for sculpture, wall hangings, etc.

Brazing 1/8" RG 45 rod together is very easy. I'm just using 1/8" flux-coated brazing rod from Home Depot and it works fine. 1/16" rod would probably be better, though. And Goehl is right when he suggests scraping off about half of the flux coating. If you don't it leaves a sticky clear residue. I think I'm going to switch to bare bronze and powdered flux. I ordered a bunch of welding rod from Weldfabulous during their Black Friday sale so I can try some smaller size rods.

I'm glad I have the Victor 100FC handle so I can tackle a variety of stuff but for tiny wire work it seems like a light duty torch might be a better option. I've noticed that Goehl also uses a Smith AW1A light duty torch a lot. For a cheaper "airline" style torch there's the Uniweld 71 and the Ameriflame knockoff. Both of them are cheap and have good reviews on Amazon.

So far I'm mostly practicing laying 1/8" RG 45 down on black iron pipe to try to practice puddle control. My results are terrible but this is a really good practice material. Cheap, easy to get anywhere, and easy to work with. I just throw a set of cheap locking pliers on one end of a piece of pipe to keep it from rolling and go to town on it.

I also did some tests welding short lengths of rebar together and that worked out OK but I think a 0 tip is too small. Probably need at least a 3 or 4. The 0 tip worked but it took a long time to get the material up to temp.

May i suggest some spot weld bits. They greatly reduce the problem of drilling through the base metal. Use a spring loaded center punch and maybe a 2mm drill bit to deepen the divot slightly (just through the top layer) then hit it with the spot weld cutter. Typically the center punch is enough, but sometimes in tight areas or with wear, the center of the cutter will wander and not stay centered when the cutter teeth starts to bite. The drilled divot helps keep this from happening.

I use this propane regulator, I'm sure you can find something similar with the correct connectors.

This uses the same connector as a barbecue LP Gas connection. It also fits a common rubber hose w/LH thread hardware (Which I covered with 1/2" Flexible electrical conduit).

Do you not have automotive repair shops? Airgas? Linde? Every country on the planet uses welders.

Heres one on amazon

Here's one on Alibaba

You tell me where your located and i'll find a store that sells welders within 2 hours of where ever you live 100% guaranteed. Even if you live in a warzone.

And even if that fails here is how you make one with super basic parts, a single microwave transformer. Spot welders are dead simple man, literally just a transformer. You could make one with literally just copper wire and a hunk of iron.

The (welder they had is this one)[SUNKKO Pulse Spot Welder 788H 18650 battery Welding Machine with LED Battery Testing and Charging Function https://www.amazon.com/dp/B01MF8LKYK/ref=cm_sw_r_cp_apa_i_Sof6Cb2C3DYFB] which is based on just a big transformer. You can set the "power" but I think this just adjusts how many mains cycles the thyrister latches on for keeping the transformer powered for more than half a dozen half cycles will kick the circuit breaker. The thing also often overheated when doing all the welding without any break to let it cool down.so one improvement would be to add a cooling fan and expoy a heatsink to the core. I am guessing it overheats due to poor design and core saturation to get the power density into a small transformer.

The electrodes were copper based, and we set the "power" close to the maximum as well as the pressure. Copper spot welding did not work at all. Nickel (0.2mm) just barely worked.

I built a much smaller 3S4P pack for my quadcopter, totalling 8AH and it worked great for a short while, but with flight times not much longer than the previous 4.5AH 3S pack that weighed half as much. Not sure if this was due to the weight or diminished capacity of the decade old cells. The quad suddenly lost power mid-flight and dropped like a brick. Besides some overall sluggishness which I assumed was the result of changing flight modes from normal to GPS assisted, I did not notice a significant loss in performance prior to total loss of power, it all happened so fast. Later investigation revealed some cells were still fully charged >4V while others were down to 3.85-3.9V. Further, that many spot welds were broke following the crash. I suspect at least one of my welds were bad and failed, causing excessive stress on the remaining cells. It may have triggered the PTC cutoff inside the cells which cut power to the craft. I lost a few cells in a thermal runaway following the disaster and had to let them fizzle out on the pavement before disposing of them.
