I hate the first video. He is teaching technique to get a good appearance weld. That is the single biggest problem I have when trying to help folks improve their welding and it is the same thing over and over.
Which circles, curlicues, little e's, c's, etc. do I use?
None, learn to hold the gun at 45 45, back hand it and build your weld by staying just at the front edge of the puddle or slightly less and use that until you get your speed and bead width figured out.
