Why is that Mark, is the ER70S-6 stronger? Seems like I was looking for -6 but had to settle for -2.

70 S-6 seems to wet in better, and has a high level of deoxidizers. And in my experience is fairly ductile.

That's because you're better than me! :thumbsup:

I doubt that. If I came off sounding arrogant I apologize.:ashamed:
I don't even have any formal training. I pretty much taught myself what I know and that isn't saying much.
What you're saying is a 1/4" weld is probably a correct weld,compared to what I would think it is.

what amperage are you using, what kind of tungsten, and what gas. (argon or helium)

I use a Lincoln Idealarc 300 AC/DC,not sure of the year,but I think it's from the late 80's early 90's.
When I weld 1/4 inch plate,I have it set on high,36/215,but I have the fine control on about 7.5,so I'm not using the full amps. I use 3/32" 2% Thoriated, "red" and 1/16" ER70S-2 rod (in fact the 70S is all we've ever bought).Gas is 100% Argon.

Ahh the classic lincoln idealarc, oh how I wish I had one of those.

I saw you can buy tungsten in 7 inch lengths, I am wondering how you cut them, isnt tungsten incredibly hard?

score it with a grinder and it will snap with minimum pressure.

What I do is put them 45 degrees to the outside edge of my bench grinder wheel, grind a groove in the tungsten, then break it over the edge of the table. Then grind the desired point on each end.

Ahh ok that makes sence. Also how much differnt is tig welding from gas welding, like if I am good at gas welding, how hard would it be to get good at tig welding.

They say the fastest way to learn Tig is to start with O/A. I haven't done any O/A welding in just under 100-years:laughing:, so I can't hardly remember what it's all about. I do remember it being very hot.
The similarities of the two processes are, forming the puddle, then dipping the filler. Personally I think Tig welding is easier to make a nice looking bead.
