Line 102:
* Machine strikes arc between the work and a non-consumable tungsten electrode, melting a pool of metal
** TIG welding is the most similar welding process to soldering but there's still an important difference. In TIG welding you're melting the base material and allowing it to flow together, not only adding material on top
* Filler wire is added manually while moving the torch forming a weld bead that joins the metals
* Gas shields the weld pool and the tungsten from air exposure
Line 278 ⟶ 279:
* Holding the tip of the filler rod near the puddle so that it's shielded, but not so close it melts
* Dipping the tip of the filler rod into the nose of the puddle and quickly back out again
** Contact with the puddle melts the filler rod, not the arc
* The puddle will rise every time you dip the rod so be careful it doesn't touch the electrode
* May be helpful to use stepped movements on the electrode
