I have a 115 volt craftsman arcwelder/brazer 20-70 amp. ive looked all over and cant find any thing on useing it for brazing. also if i have all the parts for it. any have any info? thanks
Reply:Picts or a model number would help. My guess is that it's a stick machine and to braze you would need a carbon arc torch. They were popular years ago, but are not all that common any more with the wide availability of cheap oxy fuel torches. A Carbon arc torch is sort of like a big oversized "tig" without the gas shielding. You strike an arc with the two carbons and use that as your heat source very similar to the way a tig torch is used.Sears useed to be pretty good about keeping parts forever. That changed back around 2000-2002. They dumped all the parts they had in their warehouses for anything older than about the mid 90's. Part diagrams were still available in their system at the service centers and it wouldn't at all surprise me if you can't find them online if you have the model number.My guess is if you really want to braze, you will want to look for an Oxy/fuel rig or an air/acetylene torch depending on exactly what you want to braze..No government ever voluntarily reduces itself in size.

Reply:I think your Craftsman machine deserves a spot next to the 8 track player but all kidding aside it is just one of the tools that has been replaced by better options.
Reply:i have this handle. this is all i have found on it
Reply:haha maybe so. but it dont never hurt to ask about the old stuff.
Reply:Yep thats a pict of a breakdown of a carbon arc torch. You will need 2 carbon rods to make this work. I have no idea what size it takes or even where to easily find them. Never used on personally myself but I saw one demonstrated back in Jr high in the early 80's IIRC. Several guys here have commented on carbon arc torches in the past. If you don't get any good responces in this thread, start a new one titled "Help with a Carbon arc torch" and I'm sure you will get some help from several of them..No government ever voluntarily reduces itself in size.

Reply:Forney published a welding manual back in 72 that goes into great depths about the usage of those carbon arc torches. Interesting reading. You an still find the book on shelves or at amazon:[ame]http://www.amazon.com/Forney-FORNEY-WELDING-MANUAL/dp/B000VYJ34Y/ref=sr_1_1?ie=UTF8&qid=1310871789&sr=8-1[/ame]
Reply:I used one a long time ago. Did some brazing w/ it but it was really difficult to control the heat. An elec arc is a whole lot hotter than O/A flame and it's hard to turn it down and you can't change tip size except by changing carbon size. I agree w/ others in getting an O/A outfit and it's more versatile.
