I'm currently in school and part of my program I have to learn some welding. The welding class is doing TIG at the moment. I don't have the steadiest hands so my welds aren't all that good, on top of that theres a bit of an ass in the class that likes to mess with my machine and set amperage up while I'm welding etc. I wanna get him back.. but not in a way where he can get hurt or cause more trouble then the laughs are worth. I've heard that magnets can mess with the arc so I wanna try something along those lines. I know this is terrible.. two wrongs don't make a right etc, however the teacher hasn't been able to help me either. No cameras and too many students to really watch over. If you have any ideas for a fun harmless way to get back at him I'd be interested... again I'm not looking to hurt the person or anything that drastic. Just kinda make him paranoid that he needs to watch out too.
