Burn the Bolt Out - Spent a few minutes defeating rust with me.

I love this torch, I could imagine life without this torch.

Tanks are expensive, so getting a kit like this with tanks is a pretty good deal, even though they are on the smaller side.

It's always super satisfying to see heat beat rust. If you can't use the torch directly on the part, induction heating also works fine.

I've done that just to have what I was working on pop out of the vice and have to start over.
