I am looking to buy a decent set of Oxyacetylene torches/regulators/hoses/set.
Any recommendations? Any brands to avoid?

Heating/bending metal, breaking bolts loose, cutting, brazing...

Something to remember about heavy duty torch handles is the physical size is bigger.
While the ability to cut seriously thick steel is almost never utilized, the handle being longer and larger in diameter makes it easier to hang on to and manipulate while cutting, as you can keep your hands farther away from the cut. It also stays cooler easier having more thermal mass.
The big cutting tips also preheat faster, even if you’re still using a small oxygen jet orifice, the preheat flames will be more intense on a bigger tip allowing you to get cutting faster. They also allow for more intense localized heating which is beneficial in flame straightening applications.
I personally only would want a small torch if I was doing a lot of light brazing or welding where I needed to manipulate the flame constantly and am working a puddle.
It’s called a leather welding glove. If you’re cutting big beams, scrapping, or lots of heavy 3/4”+ plate, sure, you should get a large torch. At that point you should probably step up to a dedicated cutting torch with 18" body instead of a welding handle with a cutting head.Something to remember about heavy duty torch handles is the physical size is bigger.

This is not correct. A size 0 tip for cutting 1/2” thick steel has the same size outer ring preheat orifices no matter the torch size. A victor 3-101-0 tip for a 100FC/CA1350 has the exact same orifice size/settings/heat output that a 1-101-0 tip for a 315FC/CA2470 does.The big cutting tips also preheat faster, even if you’re still using a small oxygen jet orifice, the preheat flames will be more intense on a bigger tip allowing you to get cutting faster.

Not really. You can get " heavy preheat" tips in the common sizes for the popular brands( Smith, Victor and Harris). Typically those tips will require slightly more fuel than normal preheat tips .It’s called a leather welding glove.

But that is not your average user cutting off bolts or using rosebuds to heat frozen bolts and rusted parts and brazing.

The only way to get more preheat is to get a bigger tip (in either body size) and will have larger oxygen jet orifice and larger kerf/more slag.
Its like suggesting only 3/4" ratchet to drive all your 1/4"-3/8" and 1/2" sockets via step down adapters even though they are just working on cars

Dr Clyde didn’t say anything about heavy preheat tips, he made the statement that the larger heavy duty torch body/head size in itself gave more preheat and that is simply not true. The standard heavy duty tips give the same performance as an equal size medium duty tip as they have the same size orifices.Not really.

I'm well aware of all that after using torches for over 40 years. I was correcting your statement about the only way to get more heat was to up your tip size. BTW a #1 tip isn't necessarily the same throughout all manufacturers.Dr Clyde didn’t say anything about heavy preheat tips, he made the statement that the larger heavy duty torch body/head size in itself gave more preheat and that is simply not true.

In Victor heavy preheat tips (HPN tips) are only oxy propane and this thread is about oxyacetylene.
Harris has heavy preheat tips as an option but they work on their medium duty heads as well. They are not limited to their larger body size as there is no difference in the hand and light duty machine torch tip outer dimensions in the Harris line.
Smith does offer a heavy preheat tip on their large SC cutting head an not the MC. The regular SC tips give the same pre heat as equal size MC tips
But it’s really crazy anyway. While heavy preheat might be really nice on a oxy propane machine torch or scrapping heavy iron. However cutting bevels in a 2” plate is not hard with a medium duty torch with oxyacetylene gas. And what hobbiest is going to need even that capacity?
It's very possible I have the heavy preheat tips and didn't realize it, but my heavy duty torch preheats significantly faster than my medium duty torch.Dr Clyde didn’t say anything about heavy preheat tips, he made the statement that the larger heavy duty torch body/head size in itself gave more preheat and that is simply not true.

Touché I guess for at least for Smith SC and Harris torches.I was correcting your statement about the only way to get more heat was to up your tip size.

That's just my experience. And you're free to dispute it as you like. I also have been using a torch for my career as a fabricator and have a lot of hours behind a torch handle.
I find the heavy preheat a HUGE benefit, as I don't need to use a heating attachment to get more intense heat in a small localized area. This is exceptionally useful for flame straightening and heating bolt heads. In this instance, I run as large of a tip as I have because I'm not cutting and want a very intense preheat flame without having the giant fireball of the rosebud.
Yes, I have 3 hand torches and one machine torch myself and at least once in my adult life I have borrowed my dads 24” victor(operated it a lot as a teen)The cool part about torch handles is you are allowed to have more than one. If you like to have a variety, there's no law saying you have to commit to a single size forever. Once you have the cylinders, regs and hoses you can mix and match what you like best for a given situation. Torch handles aren't that expensive, and you can get them used and have them refurbished for not much cash.
