Most expensive: Laser welders. Neutec makes one with a built-in
binocular microscope. So expensive that my catalog does not list
the price. You can also lease them.
Arc welders: ABI makes them for tiny welds. $3000-$5000 USD.
Water torches (no kidding -- hydrogen and oxygen is
electrolized from the water)
$1200 - $2300. Flame comes out of what looks like an injection needle.
Good for places that are fire zoned not to allow tanks.
Smith Little Torch kits and other oxy/acet/propane
micro torch kits,
about $100-$300 plus cost of tanks and regulators
(I am able to use normal full size regulators and tanks).
Smallest flame of the oxy/acetylene model has .006 inch
orifice size.
Jewelers' supply catalogs have a selection.
