But with all the rave I have now read about the Sparkie Torch I am
With all you’ve now read about the Sparkie, I’m surprised that you
seem to think it’s a torch. To clarify, It has no resemblence at all
to any sort of torch. No flame, no fuel, no oxidizer (like oxygen),
no gas supply of any sort. It does not solder things, nor, for that
matter, does it heat anything up except the very tiny area of the
weld itself, which occurs within a very brief electric spark.
The sparkie, as mentioned before, is a capacitance discharge welder.
NOT A TORCH in any way, shape, or form.
The sparkie is a machine, electronic, with switches, dials, buttons,
a voltage meter. The working part is a vertical spring loaded ram
that holds a chuck at it’s end. The chuck holds the finding you wish
to attach. Below this is another fixture which you press your work up
against. You use the knobs and buttons and meter to allow the
capacitor to charge up to the desired voltage level. When you pull
the knob to activate the machine, that spring loaded ram slams down,
jamming the finding against your work. When that happens, there is a
bit of a “bang” sound, and a substantial electric spark between the
work and the finding as they contact each other. That spark is what
causes a welding action to take place, melting a bit of both the
finding and the workpiece, allowing the bond. It’s a virtually
instantaneous event, over and done tiny fractions of a second.
Go take a look at the thing on the Rio Grande web site. You’ll see
that it bears no resemblence to a torch of any sort.
