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
