Torch welding is dangerous unless you really know what you're doing so it's not something to get into casually. I've gotten myself burned a few times by forgetting to put my jacket on and had sparks go through my shirt. Arc or MiG/TiG is actually safer so long as you remember to wear your goggles.I have never tried to use an oxyacetylene torch. I want to, but it has never really been needed. I am okay with some engine and car repairs, especially older cars. I do know my way around my Ford Focus, though! My husband takes me when he looks at cars because I know more about what to look for than he does. We went to a car dealership two years ago when looking for his most recent car, and they pretty much ignored me. We left. (The antifreeze was extremely low, so I asked about a leak or a leaking/blown head gasket. Seems reasonable, considering it is a sealed system. The ignored me, so my husband asked. They said, "No, antifreeze gets low in the cold weather sometimes because the car uses it." Really?)
People who really know their stuff are fun to watch though, a friend of mine had an Uncle who was a master welder and he could do things like weld a gas tank on a car with gas in it.
.....And that's legit hilarious. Cars get low on antifreeze because they use it. lol.
