[TheForge] Re: TheForge Digest, Vol 53, Issue 2

[Cindy and James]

I found a pamphlet from Sears, of all places, when cleaning out an old 
file cabinet... has a diagram and instructions on how to set up a TIG 
using a plain DC welder.  If I can figure out how to post the pictures 
(2), I will, or if anyone wants to see it I can email them directly.  
The pamphlet must be at least 35 years old, maybe more, could not find a 
date.
