I've never used any tungsten other than 3/32 red. You can use it on SS, MS, AL, Copper, cast iron, cast steel etc etc and so on from thin stuff (22ga) all the way until it blows the hell up..which is awsome by the way.

This isn't just me btw. Loads of welders do this including some of the best welders on this site. RMF being one of them.

 

Yup 3/32 Red is the choice for all, for me as well.

 

I use 3/32 blue or 1/8 blue if its real thick I have a inverter machine though which is why i dont use red

 

If you have a transformer machine use zirconiated or red, inverter machines use lanthanated or ceriated.

Awesome link!

 

I typically run a green 1/8th in Tungsten. I sharpen it to a sharp point and let if round off on its own.
