1. Do Not Touch the metal when the machine is on!
This might seem like a no-brainer, but you'd be surprised how many people do this.
Why would they do that??
2 main reasons.
Sometimes it's hard to tell if a solid-point burner is on or hot enough to burn.
So when you want to see if it's hot, the natural response is to touch it lightly.
Try hovering your hand a couple inches above the metal to feel if there's any heat rising from it.
Better yet, place the tip against a scrap piece of wood for a couple seconds to see if it starts to burn.
Another reason people touch it is because their fingers like to creep up toward the tip while they burn.
That' natural. We all want to hold it more like a pencil or pen.
But keep those pretty fingers on the plastic, cork, rubber, or whatever is there. Get a pair of gloves or finger guards if you have a hard time [like me] keeping those itchy fingers from overstepping their bounds.
Lets keep those lovely digits away from the blistering hot metal.
