Torch Kit for Welding in Difficult Areas 
A miniature tungsten inert gas (TG) welding 
torch, used with variously formed interchangeable 
soft-copper tubing extensions, provides an inexpen-
sive, accurate welding capability for inaccessible or 
hard to reach jonts (see 11g.). 1 he extensions can be 
manipulated to position the weld head around ob-
structions. The soft copper can be formed to smaller 
radii than was possible with previously used TIG
torches and it retains its shape. The low cost ex-
tension heads can be shaped to fit any particular 
joint to be welded. Special silicone tubing provides 
insulation covering for the torch, which is gas cooled 
and generally limited to small work. 
The welding kit has proved effective in welding 
stainless steel tubing as thin as 0.089 cm (0.035-in.). 
For larger work, a water cooled torch which would 
offer the same flexibility and range of movement 
could be made. Such a torch could be applicable 
to aircraft, transportation facilities, refrigeration units, 
and other system installations.

No additional documentation is available. Specific
