According to RUSS M's website, it's a push.

I just finished a Welding 101 class but didn't get to do any MIG or TIG, just Oxy Acetylene and Arc welding using 6010 rod.

Thanks for the refresher.

In general, the heat goes in the direction you point the torch. So, it is usually best to point the torch slightly in the direction in which you are heading, so as to 'pre-heat' the next section. Angling the torch makes for better visibility, of course, so is preferred over holding the torch vertically.
