My first day in an aerospace welding shop, I noticed almost everyone using the same TIG cup.
A lot of that had to do with the parts that shop welded which were mostly nickel alloys, different grades of stainless, along with some aluminum and magnesium.
With the exception of titanium jobs where they used a very large shop made cup, almost everyone used the same #7 gas lens cup for every job...both DC and AC.
I am not sure anyone in the shop could really explain why they used a #7 cup but it turns out that a #7 is a good all around size cup for both steels and aluminum.
That's why we put together this new Lucky #7 Combo kit with one clear and one pink ceramic cup along with Furick mounting hardware.
