I don't always use a gas lens on aluminum... but for this video, I was using an air cooled 17 style torch so the extra mass you get with a large diameter gas lens collet body helps keep the torch cooler...at least a little bit.
I set my amperage to 200 and used a foot pedal. I needed 200 amps at first but quickly let off to 175-185 amps once the part heated up.
I used a rounded 2% lanthanated tungsten electrode and I often do that when I am in the upper limit amperage for a 3/32" tungsten.
for the outside corner joint, I rounded the tip slightly on a tapered electrode.
for the tee joint, I just let the tip round by itself so that I could direct heat into the root.
hope this helps.
