Q for Rocky D

[Will]

Rocky D (or others),
I have been looking for the Tri-Mix TIG electrode that is mentioned from the post below with no luck. Do you know a brand name or manufacturer for these? I have tried a couple of local suppliers but none of them seem to know about it. Thanks.

What kind of rod is everyone using for steel? Pure tunsten? 2% thorium? or something else? I know there are advantages (and disadvantages) to each. I have been using 2% thorium on steel, but only because that is what the books say to use. Thoughts? Recommendations?

I've used 2% Thoriated for years, but now they tell me they are harmfull The tungsten I now use is called a Tri-Mix. It starts easier and is not radioactive, and does good all around, on steel, stainless and aluminum. Pure tungsten has been only for aluminum, but I'm told that the tri-mix is better. The reason for so many types of tungsten is, that some do better at low heat, and some better at high heat. Lanthanated or the tri-mix are the preferred tungstens to use in the industry today. You can do a search on the internet and find out more that you ever wanted to know about tungsten, if you want.

There are 2 AC/DCEN/DCEP all purpose electrode, first is the EWCe-2 (orange band) with 2%ceria. UNlike Thoria, Ceria is not radioactive. And then there is EWLa-1 (black band) with 1%lanthanum oxide. EWLa-1 has similar advantages and operating characteristic to the EWCe-2 electrode.

As far as brand name/manufacturer, I cant help you out. I usually just go to the local welding supply shop and they always have a few readily available on hand so I never had to ask who the manufacturer etc.
