When I meet a customer for the first time I like to ask them first and foremost about the torches they currently use. Most of the time they answer the question something like this:
I've been in the welding industry for something going on 40 years. I've seen a lot, and to this day I still see a lot of welding operations out there that put some crazy contraptions on their welding fixtures to get their welds done. Some of them make sense for the applications, but a lot of times they're doing it to their own detriment.
