Well- I’m a Lincoln Excalibur or Esab guy first for stick wire. My favorite for all positions is 7018 Excalibur MR 1/8”
MiG wire: Harris, Lincoln or interweld.
Tig: Blue demon or Lincoln.
I have two MiG welding machines that both run .035” wire E-70s with 75/25 cover gas . One suitcase welder that runs 5/32” (1”or more thick steel flux core) and spool guns that typically run .045” straight Argon, 75/25 or tri mix.
