… where the glue gun has orders of magnitude more power and speed and the “use electrical resistance to create heat” portion of the show necessarily happens OUTSIDE the housing. It’s a cute comparison but a MIG welder is a lot more dangerous than a glue gun.

I’m also gonna pick a nit here and say “like a hot glue gun” is what you say about a MIG weld that is done entirely improperly. If the filler material is just acting like glue, you might be sticking metal together but you’re not welding. So this tongue-in-cheek description also misleads newbs into creating bad welds.

That is picking a nit. Bad welds are still welds, you just need more of them :p

It’s possible to weld so poorly that you are really brazing, not welding. And what a hot glue gun does is really analogous to brazing rather than welding.

"A grinder and paint make me the welder I ain't"

I discovered when I first bought a MIG that there's a world of a difference between "I have a welder" and "I am a welder". I used to be bloody good at oxyacetylene, too...
