The pamphlet is junk... I'd assume a bad translation. The sharper the tungsten, the tighter the arc. A broad arc will make a broad, shallow bead. A tight arc focuses the heat in a narrow band and it goes deeper. The angle of taper is less critical an heavy stuff, but you still want a point. On thin...

Yes, I have HF start. I've been testing on 1/16" and 1/8" metal. 1/8" seems to undercut less, (but still penetrates nicely on the back side) I guess maybe that means for the 1/16" metal I was putting to much heat on it. The 1/8" metal still undercuts slightly, but not as muc...

So assuming you don't dip the tungsten into the puddle, how often do yall sharpen the tungsten? mine isn't as sharp as it was when I started welding today, but I don't notice any difference in the arc (or at least, I'm not familiar enough to notice a subtle change anyway :lol: ) How rounded to you l...

The undercut is completely normal welding on plate with no filler... In any position, just "running a bead" with no filler on flat plate will do this. Welcome to the show... Steve S Ah, thanks Steve! Glad to hear this. I'll concentrate on making consistent lines, and keeping the tungsten ...

I'm a total newbie to TIG welding, just did my first set of practice runs today. I think I'm going to enjoy the slower pace of welding, compared to MIG. I'm just a hobbyist at home, making future and general fabrication for my jeeps. My practice scrap steel here is 1/16th" thick (I think), I ha...
