for general backyard/farm type of repair/fabricating,whats more practical for heating and bending, a torch[oxyfuel] or the carbon  arc torch . i know about pros/cons as far as cost, space,ect. im talking in terms of operator appeal and pros/cons of the two as far as ease of use and efficiency. im thinking of bgying a c.a.t but ive never used one.
Reply:a C.A.T?...lol.. dang!.. just get a oxy/acet. torch.. easier and waaaay better..if you're not livin on the edge, you're takin up too much room..

Reply:Twin carbon arc torches are quite rare. I have use them to braze, solder and heat metal. I have use a single carbon to braze and braze weld. I have done carbon arc gouging. I do not think it is practical to use a carbon arc gouging torch for anything other than gouging or cutting. if you find a source for a twin carbon arc torch, please share it, I would lie to purchase one. The last time I used one was to demonstrate carbon arc brazing of aluminum irrigation pipes for farmers at a local hardware store. Several of their customers had Lincoln, Miller or Hobart buzz boxes, and Lincoln made a twin carbon arc torch that was relatively light and easy to use.
Reply:oh... sheesh that's a long haul.. i understand... well.. pro's of using one is that you won't have to go out and get bottles of acet... that's about it.. you'll still have to go out and get arc gouging rods.. i would imagine you'd eat 'em up.. plus the cons of using one is that the flame is huge and uncontrollable, not as neat, and is bulky and hard to work with.. if you're not doin alot of cutting, and what you're doing doesn't require neatness, then this may be an option for you.. it's good for welding thin stuff like sheet metal too (brazing).. but.. if you do alot of cutting, then i'd look into MAPP gas.. i personally like acet., but i don't pay for it, so my opinions are a bit biased.. just out of curiosity, are you gonna do alot of heating/cutting.. cause if not, this may be the route to go.. me personally?.. not cost efficient for me.. but for you who lives way out there, might be the thing to do..if you're not livin on the edge, you're takin up too much room..
Reply:Originally Posted by 7A749I will disagree with what was said regarding the quality of cut that can be made with CAC. Very precise cuts & gouging can be accomplished in the hands of someone that knows what they're doing. It is a superior method for back gouging & washing away inferior welds.Far better than a torch in those applications. At least to me. They cut quite nicely too at around 600+ amps with a 3/8" electrode. IMHO, of course.

Reply:thanx for the replies.lookes like the c.a.t doesnt have much popularity over oxy/act. i borrow a friends set of acetylene torches and i love them,other than the portability and the hassle 0f getting the tanks filled/swapped. dont know much about c.a.t,and it doesnt sound like a very accepted process nowadays.lincoln weld pak 100 hdlincoln ranger 225gxt ac/dcoxy/acetylenepuroxcw202 victor fc100harris model 85harrismodel 16oxweld w24roxweld w17
Reply:I have a ca torch. It is very hot but cumbersome to use. You need a welding helmet to use it.

Reply:I own a O/A torch and a twin CA torch. Once in a while for small heating jobs I'll pull out the CA, but for the most part The O/A would be a better choice. For those of you looking for a twin carbon arc torch, you may be able to special order them from Lincoln. Or with a litte ingenuity you could build your own. If you just own a buzz box, a twin CA is a nice accesory. You can order rods from eastwood that run nicer than standard cutting rods in the twin CA. They have some kind of powdered core that keeps an ac arc stable. As for cutting, a dessignated carbon arc gouging torch with air compressor is the preffered way to go. But in a pinch you can put a carbon rod in a regular stick electrode holder and saw with it.
Reply:guess ill save the money and put it towards a set of tanks, the torches are availible at a hardware store here in tupper lake[victor-mediumduty], thanks guyslincoln weld pak 100 hdlincoln ranger 225gxt ac/dcoxy/acetylenepuroxcw202 victor fc100harris model 85harrismodel 16oxweld w24roxweld w17
Reply:If you can afford it get two oxy tanks and one acet. That way maybe just make one trip for three tanks as you normally go thru two oxys to one acet.                                        MikeOl' Stonebreaker  "Experience is the name everyone gives to their mistakes"Hobart G-213 portableMiller 175 migMiller thunderbolt ac/dc stick Victor O/A setupMakita chop saw
Reply:Have to add my 2 bits worth.  I have a twin carbon torch made by Forney. It may be older than some of the other members posting opinions.   It is not a replacement for an oxy set.  It is not a carbon arc gouge tool.  The flame is quite soft but very hot and bright.  I use 5/16 carbons at about 50 amps for heating frozen/rusted nuts and bolts.  Works well for heating and bending. The old Forney welding book goes into a lot of detail about using it to the best advantage. You can clamp the carbons onto a nut with the power on and it will heat in seconds, presto loose nut. No foot long cutting flame.  I don't have an oxy fuel set so I work with what I have.  A 6011 rod cranked up will cut most things although not cleanly.  I will post a pic of the torch as soon as I get back out to the garage.  Tha part no. for the 5/16 carbons is  35212.  A search of the Forney doesn't list the items any more but we have a store in town yet. I will check on Friday for sock or not.   Fred
Reply:Another alternative, which I don't think that anyone has mentioned, is to use propane-oxygen.  At least the propane is available locally, and less expensive than acetylene.The other approach is to just get two O2 and acetylene tanks.  Presumably you go to the big city occasionally on other business; that way you could just swap tanks without making a special trip.I don't know where you live, but there might be acetylene and oxygen closer than you think.   In rural areas, you might find an auto repair or hardware store selling welding supplies and gasses on the side.   I would make some local inquiry before assuming that you are aware of all the possible local suppliers.One other comment/concern.  As you probably know, it is not recommended to put tanks of gas inside a closed vehicle, due to the risk of explosion.  I do it for short distances when I am going straight home, in the passenger compartment, so I would smell and/or hear a leak.  I also tend to leave the window cracked.   Unless you have a pickup truck or other way to carry the bottles outside, that is a long way to go with a not-recommended transport method.   If it a long drive, you might make multiple stops, potentially increasing your risks due to the time involved, and the fact that the vehicle is unattended.Lots of considerations.RichardSculptures in copper and other metalshttp://www.fergusonsculpture.comSyncrowave 200 Millermatic 211Readywelder spoolgunHypertherm 600 plasma cutterThermal Arc GMS300 Victor OA torchHomemade Blacksmith propane forge
Reply:IF tanks are the problem, getting a big oxy tank and using propane is a good option.  If you are going to use propane, get the proper tips for your torch.I use carbon arc gouging a LOT.  I can do quite a bit with it.  Its cheaper than a torch and can do a better job of removing old welds, especially bird sh*t welds.  Better than an oxy acet torch for me.  I have found just heating nuts to remove them doesn't take a lot of heat (gas), just the right size tip for the job.As in all welding, the right process for the job is what you need.I have never used a twin carbon torch.  I disagree about 300 amps and 3/8 electrodes.  I use quite a few 1/8" rods with 80-150 amps or so for small jobs.Look at this job.http://weldingweb.com/vbb/showthread.php...ght=Carbon+arcand this onehttp://weldingweb.com/vbb/showthread.php?t=30308David Real world weldin.  When I grow up I want to be a tig weldor.
Reply:The twin carbon torch is not to be confused with arc air gouging.   It was the mainstay heating and brazing torch for many praire farmers who had a buzz box. A couple of pics of a Forney torch. It has thumb slide control for the arc gap, simply touch them together to initiate the arc and separate a bit to maintain. It's not as precise as a gas torch but is adequate for brazing and heating. It will not cut unless you heat enough to just melt the metal apart.  There is no cutting force to remove molten metal.   It will use up 1/2 inch carbons for some serious heating. Attached Images

Reply:Oxy/propane will take care of your heating/bending and cutting needs.If you already have a high output air compressor and 250+ amp stick welder, you can get an Arcair-made Radnor carbon arc torch for $100-150 at Airgas.MM350P/Python/Q300MM175/Q300DialarcHFHTP MIG200PowCon300SMHypertherm380ThermalArc185Purox oaF350CrewCab4x4LoadNGo utilitybedBobcat250XMT304/Optima/SpoolmaticSuitcase12RC/Q300Suitcase8RC/Q400Passport/Q300Smith op
