Heating a bolt with Oxy Acetylene torch

[jacked_72]

I don't have a huge need for heating bolts as I'm no longer in the rust belt, but which kind of tip should I be using when I do? I think my current tip is a #2. Should I go up to a #4 or #6 for the heating?

Ayuh,.... That depends on how big or small the bolt is, 'n what it's stuck in,....

A 1/4" bolt in a small aluminum castin', I might use a #1 tip,....

A 3/4" bolt in a massive iron castin', I'd use my big ole heat bud,....

Let's start by asking what brand and type of torch you are using. A Victor #2 is nothing at all like a Smith #2 tip, and a cutting tip is nothing like a welding/brazing tip.

Uniweld, so same as Victor. I'm not talking about the cutting head tip, but I suppose that can be used for heating a bolt too.

A rosebud is generally the go-to for mass heating. That said, I'm too lazy to change out the cutting tip I leave in my torch, so I use that instead. Less heat, but much more focused and easier to control. But, cutting tips serve the same purpose, size as said above, dependent on size of area/mass to be heated. Don't be afraid to experiment/play with your torch. Start out small and go big. Or??

A cutting tip is nothing more than a miniature rosebud with an extra hold in the middle.

That's all I've ever used (to heat) all my life working in shops.

Thanks, Good to know.

Cutting tip here too.

The only times I swap to anything other than the cutting tip is when the hardware is either really small or in a really tight place, the other time is when I have to heat a really large item or large area.
