Something strange happened when I used the 26 gauge nickel wire for the NR section of my approx. 0.5Ω 26 gauge nichrome coil. Both the NR and the R glowed about evenly red then the nickel melted. I thought I had a short so I made another, same thing, the nickel "popped".
Next I made up a wire with nickel on each end of a short piece of 26 gauge nichrome and mounted it on the terminal block that I use for load testing batteries, this is when I saw all three pieces glow evenly.
BTW, I checked the nickel with my meter and it is non-resistor wire, I'm at a loss as to why this happened.
On another note I was quite successful welding the 26 gauge nickel to the 26 gauge nichrome but I twisted it the next couple of times.
Now here's the part that's got me scratching the old head, I've been using 32 guage nickel NR for a couple of years. Right now I have a Term set up with 28 gauge nichrome at around 0.6Ω and it's working fine. I probably should make up another one and mount it on my terminal block to see if the NR is heating up there too, heck I might as well use 22 gauge Royal for NR for that matter. LOL
(my 26 gauge coil was 0.5Ω BTW)
