Way better than that this funny advertising for a school where, may be because in NZ (at the opposite of me) he see the result of angling the stick at reverse than what I think.

A comment on that old one : they take in account the eventuality of arc blow , I rarely have seen demonstrations done that way .
Is it because they think heavy steel pieces, where arc blow can be more annoying ? Or modern equipment less sensitive to arc blow (I dont think so)
Anyway I more or less naturally raise my angle in the middle of a flat piece, welding around 85° to avoid too fat bead (since I was said I give too much "meat" to my beads)
