[TheForge] tig

[Woolley]

Bob,

All you need is a DC power source. I disagree with another post as to 
how a manual torch (valve to let gas thru on the torch head) is a PITA.  
It's like turning water on and off .  Sure, you will damage your 
tungsten if you light up without gas. I use this setup exclusively and 
do a lot of tig welding .  I'm a pretty good welder and still have to 
sharpen plenty of tungsten.You don't need a foot pedal to regulate 
amperage, just set your heat at the machine and adjust up or down based 
on what you are welding (different thicknesses, materials etc) Tig is 
welded with strait polarity so the ground is positive, torch negative.  
Argon gas, approx.20lb pressure on your regulator. Piece of cake.  I 
learned how to tig weld building and repairing boilers in the field. We 
didn't weld with pedals etc.  On a big job we were lucky if they had 
remote rheostats to change our heat without running to our machine and 
back if we were switching from tig to stick etc. I believe there is a 
mystique about tig welding, that it's specialized so it's harder than 
other forms of welding. Like anything else you want master, it just 
takes time and practice.
