  • welding Stainless with Oxy-Acetylene

    Can 304 stainless be welded with an oxy-acetylene torch?

    No you can't weld it that way.

        Yes, it is weldable with an O/A torch. Use the proper flux and TIG filler rod. If not near a welding supply, Tinman sells this flux for stainless. His products are excellent and reasonably priced.

          It takes some practice. This is 10 gage 304 stainless with TIG:



          Lap joint, same material/thickness. Colors are a bit washed-out by the flash, but you get the idea:

            HERE is a copy of Chapter 18 from the Linde Oxy-Acetylene Handbook that was referenced in the linked thread.

              I see you didn't get the heat shield in you kit either.

                I asked about the heat shield but they didn't have any in stock and advised me to make one a save a few dollars - which I did.

                They provide very good support here in OZ.

                Its a good kit. I use mine instead of my standard O/A kit and it saved me buying a TIG set and so saved me floor space and another rental bottle (for TIG).

                  Nice kit, what are the trigger looking things on the handle for?

                    does it need to be a weld or will brazing do? ( easier, less HAZ & just as strong)

                      The trigger is the same function as the lever on a standard cutting torch. In oldtiffie's picture it is rigged for brazing and the trigger is not used. For cutting you attach one of the squiggly bits on the right hand side of the case in the picture, and then you use the trigger. I especially like the one with the training wheels.
                      Oldtiffie, what did you use to make your heatshield, what material and pattern?

                        For BM: HSS has explained it correctly. The pic (pages from the manual) showing the set-up should help.

                        For HSS (Patrick): I just use a bit of scrap sheet metal or tin-plate from a can - when it looked right and worked right it was right. ie just "top of the head" stuff. I just make them as required. I usually just use MIG/TIG welders gloves and forget about the shield.

                          Nifty setup with the dual tips for cutting. Thanks for the pics.

                            The dual tips are oxygen and acetylene
