consumable question...

2% lanthanated is good for everything.

Can you use the same rod for both Aluminum and steel??? Or for all metals?? To be clear the same piece of tungsten for different materials or would their be a cross contamination??? For example I was told to use a liner on a MIG welder when I used aluminum wire and to remove it when I went back to steel.

Yes, the same piece of tungsten can be used for whatever you're welding.

I see tungsten is sold in 6" and 7" will the 7" still fit in the standard torch???

Yes but I like to cut them in half and sharpen both ends so you have four ready to use ends out of one piece.
