That might work well. Have a spotwelder in the workshop here, but
a bit to clunky for fine wire work. I'm still considering buying
one of the commercial pulse arc welders, but would look at those
made for jewelery work, rather than those for thermocouples, where
you put the twisted ends into a hole in the front panel. Afaics,
the jewellery use a tungsten electrode, where the tip is withdrawn
from the workpiece on contact. Then a hv supply starts an arc
across the subsequent small gap, conducting and forms a plasma
from the discharge of a capacitor. Seems a clever idea to me
and could be useful in the lab here for other purposes as well.
More fun to build one though, given the time :-).

I did tried soldering, as the oven temp is only ~60 c, but failed
miserably, even using acid flux...
