  • tig steel vs tig aluminum

    I practice my tig welding in the morning for an hour before I go to work. I notice that the arc is so much quieter and more stable when I switch from aluminum to steel (switch from AC to DCEN of course). All other settings are the same ( I do use gas lens). I did some research and I found this comments from weldingtipsandtricks.com.

    "when you tig weld aluminum, too little flow or too much flow of shielding gas makes a big difference. and just a little too much flow, can make the arc really loud and make the arc erratic."

    I set the flowmeter between 15-20 cfh. Do you change the flow rate between the steel and aluminum? Do you increase the flow rate for thicker metal?

    I leave my gas flow rate at 15 to 18 cfh with either aluminum or steel. And I always use a #8 gas lens.

    Most likely the reason you notice the aluminum welding being louder is because you are welding with AC settings, which is correct with aluminum.
    The DCEN is much quieter, not having the 'buzzing' sound when welding steel..

      AC IS louder no matter what you do. I have done lots of both and I don't change mine, I set mine at 15-20, mainly 15 unless I am in a windy room or something with air turbulence.

      DC Is much quiter and you can't even hear the arc but you can hear the gas if its quiet. AC You can dream about hearing the gas and it's allways loud, the higher the frequency the louder it is.

          I listen to music, got the Beats wireless, Bluetooth head phones a few weeks ago, been using them ever since, every day, every time I weld. Sound cancelling the outside and some seriously nice sound. That does it for me, can barely hear the buzz on AC.

            You haven't said what your machine is. I went from a sine wave Dialarc to a square wave inverter Dynasty. In every other measureable sense the Dynasty blows the Dialarc out of the water. Noise is another matter. On higher frequencies I use ear plugs to tolerate the buzz. DC is classical music. AC with inverter technology is head banger, smash the guitar industrial noise.

              I am using Symcrowave 180SD. Is that a sine wave or square wave?

                I never notice any noise, be it welder, water cooler, air tools, dogs barking, car crashes nearby, etc. Only thing I hear is this..



                Could it have something to do with it? lol

                  Mark Knopfler's guitar work is unparalelled & the studio work is soooo clean and sharp....

                  the noise floor is so many DB Down.... as to be undetectable............

                    I beg to differ. Kneel before the king. The one person Guitar World refers to as "his royal Highness"...the very first artist to have a Fender Signature Series guitar, even before Clapton, true pioneer of a genre....

                      We all have our own personal preferences................................

                      But you might take some time to listen to Knopfler... the studio work... not the live stuff

                        Oh and he even has his own Sharpie marker. Made specifically for him, by Sharpie. How cool is that when signing autographs

                          I sure do not begrudge you your choices..... our outlooks differ..... I am a little older... was raised in recording studios and audio labs...
                          back when all that tube stuff was new............
                          As a child..ln the 50's. it was not uncommon for Les Paul to show up at our door bearing pizza and beer .... wanting to pick my dad's brain on some recording problem....you see.... My dad designed and built the first 8 track recording console for Les in the middle of our living room...

                              I am lucky... my father was a genius and probably the best audio engineer of the 50's and 60's......
                              he invented and designed many things in the field that are still considered the gold standard....
                              including the "Fairchild 670"
