Which torch to get?

[ihaveaquestion]

Straight copy from another forum, just thought I would get some quick feedback on this board in case there is a definite "Oh No! Don't get this!"-type of suggestion.

"Just need something to loosen stuck nuts/bolt on the car. Wielding would be nice but don't have the know-how.

Yesterday, I was working on one tranny mount bolt for a good 3 hours, after lots of yelling, cursing and looking up the blue sky, wondering why I was underneath the car instead of playing outside, I finally gave up. Penetrating oil didn't help. Plus I can't get a good torque on the bolt either.

Anyway, after lots research, I came to the conclusion that heat might be the only answer now. So which do you recommend? I see Home Depot has one for sale for $15..."

My main concern is whether the flame will be concentrated enough seeing how big the mouth is.

Self ignitor is a big plus for me.

Good review. Self ignitor comes with it.

Gets up to 3600 degree. Enough said.

Make sure you buy a yellow top propane or something that heats up to 3600 degrees. Also make sure it is for Medium to heavy soldering and brazing or higher.

So from what I'm reading you have a stuck bolt and you ware wanting to weld it out? How would welding get it out?

I was wondering what he meant by welding the stuck bolt. I assume he meant loosen it by heating it up with a torch, since that's what it appears he's going to do.

No, i just want to heat up and loosen the bolt. No welding.

Just wondering which torch, and what temp is required to sufficiently heat up a bolt.

Any propane torch should do the trick, I'd go for the cheapest, specifically if its a one time use. Shops will use oxy-acetylene torches, however, that's a bit expensive for home applications. Otherwise, just soak the mofo in penetrating oil and make sure you have the right sized socket. Also, use a breaker bar and a pipe on the end for more torque.

Also, temp won't matter, you want to heat up the bolt, but not to the point its malleable(not red hot) unless you plan to inadvertently weld the socket to the bolt. And if the bolt goes into a rubber mount, don't even try with a torch, just soak it in penetrating oil over and over.
