yeah I dont believe those are hand tigged. even though some pics show a dudes arm and an arc struck… absolutely ZERO inconsistency, side to side, start stop, between filler dabs, etc. unless they were jigged up on a rotary table or some machine to spin the part consistently, where you just steady rest the torch and add filler… I call it BS that those are 100% hand tigged.
If they are, the man just isnt human.
