I am wondering whether to use acty or propane. All I have even used is acty. I'm AUS propane is way cheaper but what are the pros and cons? Can someone please help me!
Reply:I switched to propane couple years ago. Little slower for preheat, and you'll need different tips. But it does cut nice.

Reply:Looks great! Would I only need new tips? I don't need a new torch? Can I continue to use my victor torch? Are you glad you switched? Has it been cheaper for you? Would you recommend it over acty?
Reply:I just switched to Propane for cutting. I have a medium size victor torch. So far I think it cuts as good as acetylene, maybe a little better. I know the burn when I light up is cleaner. I very seldom cut anything Over 3/4. I have found that you have to be a little more steady handed. Mac

Reply:You don't need a whole new torch, just propane tips. You shouldn't have any trouble finding propane tips for a Victor torch. Try it, you'll like it!
Reply:Slower preheat is sometimes not really so.If you've run acetylene all your career you have a tendancy to do the preheat WRONG with propane. You don't have to hold the cutting tip as close to the steel with propane. The hottest part of the flame is not in the blue cone like acetylene.It's given propane a bad name, and unfairly so.You'll also notice a different type of oxygen stream effect with propane. It's gentler, and doesn't throw hot slag all over the place like acetylene tips. Handy where there's fire danger present. As yet I haven't had to use the propane in a situation where I need to extend a cut with the oxygen stream (say you're cutting a piece of steel, and can't follow the cut with the tip, and need to start the cut with the tip in one place, leave the tip where the cut started, and blow the cut along a long line........handy in demolition or where space is limited). But I'm favorably impressed with the qualities of most propane cuts.The cost of acetylene is pushing it out of the cutting market in my opinion."Any day above ground is a good day"http://www.farmersamm.com/
Reply:Nobody mentioned needing 'grade T' hoses with oxy-fuels. I changed over. Is that an old wives tale?
Reply:Also remember that you will need fuel hoses rated for use with propane.The 'regular' acytylene-only hoses are the "R" or "RM" hoses.The 'any-fuel' hoses are the "T" hoses.The torch handle, mixer, and cutting attachment are usually usable with acetylene or other fuel gases, but as mentioned, you will need the propane cutting tip The best laid schemes ...

Reply:I've always used Propane, reserving a small tank of Acetylene for brazing/welding processes.
Reply:I recently switched to oxy/propane. I give it a thumbs up! It cuts great and the pre-heat time does take longer. Like 2-3 seconds longer.

Reply:I use propane. If you are buying new hose, get grade "T". That said, I have been using my grade "R" for years, although not everyday. But I am not recommending you do this, I am just stating what I have done. When I need to replace my hoses, I will get grade "T"."Where's Stick man????????" - 7A749"SHHHHHH!!

Reply:I'm using BBQ tanks...light, cheap and easy to swap.
Reply:Just use a 20lb bbq cylinder. I never really paid attention, because I might use the same cylinder for a heater or weed torch, but I am "guessing", you can get 2 to 3 large "K" cylinders of O2 with one bbq size propane. If anyone else has a more exact figure, please add. I don't really remember seeing that info here."Where's Stick man????????" - 7A749"SHHHHHH!!

Reply:My bud cuts up scrap metal for a living with a large company. They recently blew up some hoses that were not " T " rated. They only use propane.I like propane because its cheap. It does burn more oxygen. There is also no draw rate so you can cut longer. I have cut so long with propane the bottle froze to the floor.

Reply:I am a big fan of propane in the field / natural gas in plant easier starts, no soot bats, no loud popping when you have a little metal blow back or over load the tip. I have used both and just two weeks ago made the switch to propane on my truck.Ranger 250 thick stuffHobart Handler 140 not thick stuffthe pane and oxy setup
Reply:So "T" grade hoses are a must when using propane? Or can you use your normal acty hoses but will just chew them up and damage them or what? Can they not hold as much pressure?
Reply:Originally Posted by MondoYou can use the little pig, if you like. I have a Ranger pickup with a cap that is the same height as the cab roof so I bought a 70# tank from my LWS. It is the largest I can stand upright in the bed under the cap. I have had it for a year now and it's still at least half full.Inspection on the cylinder is good for twelve years. As I own it I will need to pay for inspection when due. The counter man said the price of a new cylinder is about the same as the inspection fee so I figure in 2023 I'll slice it into a BBQ cooker and buy a new tank. But I'll be 71 by then and may not even be doing metal work, if I am working at all!- Mondo
Reply:i believe the propane gas degrades the hose at faster rate than acytelene (sp). i'm like stick-man, though. i've used regular hose with propane for some time. when i buy new hose it will ne t-grade. not saying this is right, just what i use.

Reply:I guess O/A is the jack of all trades: cut, heat, weld. Plasma is great for cutting., but it's a one trick pony. Just does that very, very well and it's quick.Oxy/propane is great for heating and cutting, but not welding.Of the three, only O/A can weld (AFAIK) but it doesn't look like O/A welding is used much any more, there are better (quicker, easier, cheaper) ways. |
