  • a setting on my HF-P

    I can weld SS pretty easily, and it comes out nice...but I have lots of trouble with aluminum....and It seems its always been that way with this machine at work. I haven't welded on another tig, so I have no comparison. But I look up videos for help often and it is night and day what the weld process looks like on the video and what mine looks like.

    there are times when I can get decent welds on aluminum, but it takes a LONG time to get there and it is slow, and the position of my electrode is so critical... when cleaning and heating up, the machine has a certain sound and as soon as the aluminum wets out the machine changes sound to a smooth sound...but if I lift the torch ever so slightly, I lose the wet puddle and am back to that nasty sound... sometimes I see the arch moving around on the electrode...If I contaminate the electrode, I clean it and start over. yesterday I used lathanated and balled the tip 3/32" dia, and was welding 1/8th aluminum sheet ( 5052)that had been tacked previously by a vendor who bent some sheet for us. MY 100% argon was flowing at 30 psi. I looked at a video and the guy was welding in 2 seconds and he traveled at least 6 " dipping his filler in a nice wet puddle in about 10 seconds worth of time!!! it takes me way longer to weld that length . so I am THINKING the AC on this machine might have issues... or I am not set up right....so the main question is...

    what setting should the HF be on when doing aluminum?

    start,
    off
    continuous???

    I have always had it set to START...

    thanks

    For aluminum you need continuous, and AC. What machine are you using? Settings? Material thickness?

      thanks

      I just saw a video today that said CONTINUOUS!!!

      dam, all these years

      my machine is a Dialarc HF-P

      .125 aluminum 5052,.....4043 filler

      water cooled 280 amp torch

          Yep you will want CONTINUOUS HF AC for Aluminum

          You will want to read the TIG Guidlines Booklet to better understand settings

          These 4 videos are really good info on technique for AL TIG

            thanks , but all I got when I opened the videos was youtube and an exclamation point in a circle...

                it opens now....

                I went ahead and set the machine for continuous and cant believe how easy the welding became...

                it would have been 10 times easier to weld up that boat gas tank if I had the switch in the proper setting!!!!!!!!!

                I just welded some .080 sheet aluminum, edge to edge in a butt weld... it went so smoothly!

                thanks

                  Glad you got it sorted out..

                  you might want to print out that 24pg TIG pamphlet and keep it near the welder for quick reference...

                    LMFAO, well I'm glad you knew what you were doing the first time. Your ready to start welding for NASA now that you have your machine figured out.


                    And its CFH (cubic feet per hour), not psi. And it should be in the range of 15-20 depending on your cup size, and I dont mean your bra.

                      a setting on my HF-P

                      Well I would imagine welding with the proper settings is quite a bit of an improvement.

                      It's not like you had one of the most important aspects of TIG welding aluminum turned off or anything.

                      But I'm only poking fun at you a little bit. It's all in good humor.
