Smith Type Little Torch - Genuine American Artorch Straight Wedling Nozzle

Micro welding nozzle designed for use with oxy / acetylene.  When used with oxy / acetylene may be used for fusion welding of steel and other materials when using the correct flux.  Flame temperature is normally 3106°C.

The standard oxy / acetylene nozzles may also be used with oxy / hydrogen where complete purity is required for joining / welding metals together.

These micro tips have very small flames and can be extremely difficult to ignite.  The welding nozzles size 1 to size 3 have the outlet orifice drilled through an industrial sapphire to ensure correct size and flame shape.  Sizes 4, 5, 6 & 7 have a swaged outlet.  See picture 3 & 4.  Picture 3 is with a fibre optic light passed up to the sapphire and the illumination passing through.  Picture 4 is with the light turned off - #2 holes size is 0.006".

There are nozzles which have been designed specifically for use with oxy / propane, oxy / propylene available which may be used for brazing and silver soldering but of course cannot be used for welding.

Stock of size 1 is limited as this size has been made obsolete.
Please note that these are genuine American parts imported from America and not cheap copies. 
The cheap copy nozzle do not provide the correct flame size or flame shape which makes the nozzles difficult to work with.
