RE: [CAD_CAM_EDM_DRO] Re: Gecko burned out

I'd have to second this logic.

I usually tin the wires with a nice hot iron, and draw it down, only
just thinly coating the conductor with solder so that it's still very
flexible. I'll then snip the end, so it's got a nice square profile. The
allows it to be snugly tightened into the terminal.

Of course those nice boot-lace ferrules are the neatest, but expensive
for the kit and the crimps and I already have a soldering iron and lots
of solder...

My 2p.

BTW, did you know that tinning stranded wires is NOT recommended for
wire-clamp-type terminals? The manufacturers specifically warn against

Yes, I had read that. I imagine if the wire is twisted loosely and the

solder is globbered on so thickly that it increases the "gage" of the
wire one or
two points, this is valid. However, if one twists the wires snugly,
leaving
a little excess-length on the tip, tins with FRESH, clean solder not
full of
copper-solute, drawing the tip of the iron downwards, with the wire
pointing
down, so that last drop falls off the end, THEN, clips the excess off
the
wire-tip, the result will be VERY little "flowable tin" in the tip, and
all the
strands will stick together as "one wire", rather than like a witch's
broom
with some strands sticking all out, about, causing shorts! I've SEEN
it, and
when pointed out to the fabricator, the response has often been, "So?"
