Two fill ups ago, I got a bad tank of argon. It was like I was trying to weld with CO2. After that, I shelled out and got a large tank to use as the main tank, keeping my smaller one as a backup.
Now I've got my (freshly filled as of Friday) large tank and the weld has an almost porous looking finish; like the weld itself has been shot blasted. When it welded, it looked like there was a very small amount of contamination in the weld pool; the type of contamination that you should really stop and clean, but nothing really to worry about - especially for the small jobs I'm doing for myself. Now it is possible that well, maybe I'm imagining this, and I'm just having a bad bay, but it's the same on all tungstens, and doesn't make a difference if I'm at 65 through to 75% cleaning, or if I go from 80 to 200Hz. There are only so many settings on a 200 DX after all. And yes, I'm on AC lol...
So I jump to my smaller tank (also filled Friday) that now acts as my backup when I run out of the large tank, and once again, it's like I'm welding with CO2- same as several fill-ups ago...
I am obviously going to go back to my supplier on Monday, but the last time I took a tank back, they acted all surprised like I was a freaking idiot, as no one else had complained. I'm almost at the point of asking for a refund and telling them where they can put their tanks, and going with Holsten gasses - who are actually closer to me...
I'll post some pics of these awful welds later, but I was curious if anyone else has had the 'shot blasted' weld appearance before, and just maybe, today, I'm doing something silly...
