Hmm... so if i was in the market for classic TIG rod how would I know that it's 40 years old and not something you bought yesterday? ER70S2 is a common TIG and MIG wire.

I missed the humor, one thing the Internet is not good at is indicating tone. I find humor and sarcasm easily lost.

ER70S6 is the most common MIG wire when I went to school I was to it makes up about 70% of wire sales, I am assuming that is solid wire sales. Relying on my memory from bacm when I went to school, both ER70S6 and ER70S2 use silicon as an oxygen scavenger with the s2 having sight lyrics more. The s2 is better suited to automated processes and gives a little better wetting action along the edges.either is fine for MIG or tig mild steel applications but the s6 is cheeper and what I use and recommend for MIG.

I my little shop, I mostly use either Hobart HB28, or Lincoln L56 for steels, both are E70S-6. Whatever is cheaper at the time is what I buy more, since as far as performance, and appearance, I can't tell the difference.

As I understand it, from my welding gurus, the silicon helps when welding through rust, dirt , and mill scale. Much like 5P.

Most of my TIG welding with steels, is on things that don't really matter much what I use. I have that one old tube of E70S-2, but it's to big to use on things like exhaust pipes etc.

Only thing I know that is "lower temp." than TIG with 70S-2or6 steel rod would be TIG with bronze filler. But you would have noticed the yellow color.

There isn't a single ferrometallic alloy to my knowledge that melts below 1100°C. Most of them do arround 1400-1500°C. So the low temp "welding rod" must be a brazing rod...

Also, stick welding yields temperatures around 6800°C for ferrometallic alloys.

Exhaust pipe = coat hangers in my shop. Mostly gas weld tho for heat control, puddle and step.
