  • Practical uses of arc torch...???

    I found a Craftsman arc torch in my shop cleanup. It's not the type with air blowing the molten metal away.

    Do these have any uses these days?

    Is it one of these? https://www.youtube.com/watch?v=DYnsCXVsJsw

    Carbon arc torch, 2 carbon electrodes.

    Never used one, maybe others have?

    All of the gear, no idea...

      Used to repair battery terminals with one. A little mold and use the battery own power to melt some lead onto the terminal.

        i have one and its nice if you dont have oxy/acetylene. i used it to bend sway bars for example.

          I have an old one, probably from the mid 1950's. I find it a bit touchy to get the right arc going but it works good for heating things for bending. Hotter than an oxyacetylene and you don't need to refill tanks or pay rent on tanks. For the once or twice a year that I need the heat, oxyacetylene was expensive and it seemed like I always had one tank that was near empty when I needed it. I think it works better on an AC welder than DC.

            That looks useful, but perhaps TIG could be used similarly and more controllable? Would likely need shielding gas though.

              It does work better on AC. DC wears the electrodes unevenly.

                I remember repairing one of these back in 1979 in South Africa

                  good for brazing and soldering, or just applying a lot of heat in a little spot. Not commonly used much any more, most people use oxy-acetylene, or TIG.

                    Useful---electrodes on either side of a nut --- red hot in a moment!

                      Thanks guys....

                      I should have said "carbon" arc torch, but I guess everyone knew what i meant

                        I've used a single carbon torch years ago to weld sheet metal. With our welders we could turn the amps way down similar to a tig welder and small dia. filler rod and could weld 18 ga galv. pretty easy.

                          I have one of those single carbon torches too but never knew how to use it. Now I might. Thanks.

                            They also give you a hell of a sunburn, even through clothes, ask me how I know!
                            there used to be a Keller carbon arc torch over here in the 70s, brutal heat, glad I threw that out

                              Now there's a skill you don't see too often any more, I've heard stories like this but never had the chance to try it.
