Harris Acetylene Torch question?

I have a Harris Acetylene Torch set #225 and would like to have a Rosebud for it, but I don't know
which one to get, the handle where gas control knobs are says #85 I think it is kinda worn from
holding on there I guess. Anyone know what Number Rosebud to get for it, I see all kind of Numbers out
there but don't know which I need? Thank You

If it is an 85, I have the same one, and the heating tip /rosebud is, I think, a 63? This site seems to indicate a 'J-63'. Scroll down to the bottom of this link and you'll see compatible heating tips.

If you're using acetylene, keep in mind you need a big tank to handle a decent-sized rosebud. Look up the charts for whatever tip you get: you can't withdraw more that 1/7th the cylinder volume per hour. Ex: if a 10 cubic foot cylinder, you can't use more than 1/7 of 10 - or 1.4 cubic feet per hour. Otherwise you draw acetone out and damage your equipment, and is also be dangerous. For very short periods, you can push that limit a little, but not much.

Actually, I think a lot of places now recommend a 1/10 rather than 1/7 rule. Rosebuds take a lot of gas, so unless you have a really large tank, you're often limited to a rosebud that's not much larger or more effective for heating than your cutting tip would be.

If you only use your torches for cutting and heating, it might be worth considering changing to propane instead of acetylene. There's no 1/7 rule for propane. It requires a few different tips, but is a lot easier and cheaper to refill, and does just as good for cutting & heating. You use a little more oxygen, but the savings and convenience of propane more than make up for it.

As others said, they take a lot of fuel! At the price of acetylene today, maybe consider switching to propane, at least for heating. I have my Dad's old Harris from the 60s, and it has been used with propane much more than acetylene. I've found that a big propane cutting tip will stand in for a rosebud in a lot of work.

I've used propane for about 20 years now. there is a slight edge to acetylene heating cutting I don't see a difference. I'm not going to change away from propane either in the near future. Dad has an acetylene and it works good just costs more to operate. The tip is a fluted or veined piece inside a sleeve for a tip unlike the other being a one piece affair. If you can't heat it with your current torch you probably can't do much better with a rose bud due to the limits of draw down on the acetylene. You could however build a fire and heat it that way probably cheaper and faster once you have the fire. Start with a bon fire and toss it in while doing that then bend what you need.

I use propane for heating and cutting then switch to acetylene on rare occasion I need to gas weld. I also have a homemade propane-air forge for items which will fit into it plus often use forge burner in hand for large items. If you do much heating and bending google Frosty T Burner or go to IFORGEIRON to find answers to about any question you can think of on the subject. After reading up you still have a question,join and ask. If you don't come away with anything else you will learn propane can melt steel using air and people that claim propane with oxygen isn't hot don't know how to adjust and use a torch. It is true propane doesn't weld good but not for lack of heat,it doesn't supply shielding gas like acetylene does.

I can't tell you the numbers but I have a rose bud on my 85. I rarely take it off,I run a # 3 acetylene tank. By the numbers it is too small of a tank.but it works ok as long as you don't try to run it wide open. I do have another set for cutting so if I get into some really heavy stuff I just preheat with the rosebud and cut with the other,work good. (inch and a half steel last week)

Thanks Guys, for all that good info. Gene
