Default Hydrogen blend for stainless tig

I have a couple of pics attached that I welded up with a 2% Hydrogen/bal. Argon blend on stainless steel. this blend works only on 300 series stainless steel. the hydrogen blend is used for increased travel speed, much better puddle fluidity and excellent color match on these steels.

That's absolutely beautiful!

I would not have imagined adding explosive Hydrogen to the gas mix to be a good thing...

I've used it in the past, works great on SS welds, the LWS, no longer stocks it, and its now a special order from another gas supplier, that works with the LWS, ends up being expensive, long lead times and a lot paperwork, for me too much trouble to deal with. Very nice looking welds.

Thanks for the compliments. Since I'm in sales for a LWS, I do a ton of research for my customers, trying to help them improve productivity, lower costs, etc, and since I love tig welding, this one was a no brainer.

Looks good.

I was told by a guy in charge of a welding department to use the largest cup you can get for SS, he said it would help stop or eliminate that blue discoloration.
he gave my friend a 3/4" cup but we never got around to trying it, I think he said 3/4" is the minimum we should be using.
