If you want to master the techniques of TIG welding, my advice is-first learn how to braze and run a puddle on the parent metal (usually cast iron) with the oxy-acetylene torch- remember, before Lincoln (Electric, not Abe) developed SMAW- shielded metal arc welding- we had : soldering, brazing, and welding- all done with the torch and appropriate tips--but, in those days, plumbers had to be able to wipe a lead pipe joint. TIG is King of the welding processes- you can weld any ferrous or non-ferrous metal with TIG. RWTF
