There is a difference, but my point is, for most applications you don't need to spend 30 minutes prep for a 30 second weld. 30 seconds prep will get you where you need to be.
There is a time and place for everything, however when teaching you don't want someone to say, "I wasn't taught that" still common sense and experience should win the day.
Good post Steve
I should have added, for the student, there's nothing wrong with surgical clean. There's nothing wrong with removing every possible variable but one's settings and manipulation. The best way to learn is to remove any variable not directly related to working the torch, puddle, and rod.
For the experienced welder, there's a scale of "how clean do I need it?" based on the material and the purpose.
