An Elec-trak welder is up on Ebay. Price IMO is way high ($330) and
that's
without the welding cables.
However I will say they are pretty nice actually. But really, it's a
strap
resistor set. Hm, does anyone know if one can make a welder out of the
E15-20's main resistors?
<<<<<<<<<<<<<<<<<<<<<
I believe one could probably do that. Some years ago Popular Science (or a
magazine like that) had plans for building a welder that could be used on
120 VAC household current. It was very simple - a resistance wire in
series
with the ground and electrode wires. It is limited to the amperage
available fron a standard 20 amp circuit.
I still have the one that I built, using a heating element from an
electric furnace. You have to use a very small welding rod, and it is
difficult to
start the arc, but by golly - it welds. I also built a carbon arc head
for
this which throws one heck of an arc.
I would suppose that the low voltage/high amperage available from the
Elec-Trak would work even better. I would guess that if you look inside
that
Elec-Trak welder it would have little more than a resistor strip inside
it.
Has anyone looked inside one of these?
BTW - The Ebay ID number for this one is 110609278471
