Great example of heat input. I always say if you touch a hot frying pan quickly you won’t get burned but if you lay your hand on it you will. Lower amps doesn’t mean less heat.
I always try to move as fast as I possibly can until I reach the point where the puddles start being “V” shaped instead of “O” then I back off the speed a little.
Watch your heat affected zone or “HAZ” on stainless it should be no more than very light gold!
