We've got a bunch of sheet metal clips to attach
to 2mm stainless steel rods.? Hmm, how to do this.
Then I hit on it.? We have a Docreate spot welder for making up

using moderate force (any more and other things would break).
So, spot welding it is.
That Docreate welder seems like a nice machine.? Well thought out
and works.? We haven't had it too long so can't say how well it
lasts, but it also wasn't expensive.? They sell a range of
welders, here's the one we have
