not sure the right section for this question but because im working with auto related AL. welding thought id ask here.

today i had the opportunity to be instructed by a long time very skilled old salt,and was able to ask alot of questions and get some really good advice

he let me try several different types of lenses in his vintage mask that were
different colors,and WOW what a difference in the view of the puddle and the work piece,so now im spoiled and am searching for the lenses on the interweb
ive only been able to find the gold, he said some of them were no longer made
like the "cool blue"

my question is anyone know sources for somthing comparable to the blue lens and were to find it?


thanx
