How to weld TALL weld beads on 1.6mm thick Aluminum Tube?

Hi welding gurus .
I once saw a welder at a car-speed shop several years ago build weld bead on top of thin-walled aluminum intercooler pipe (~1.6mm aluminum tubing). Although, I've had success with my EverLast 225LX machine, I'm having difficulty creating a tall weld-bead around the end of this thin-walled aluminum tubing. Does anyone know how to do it without burning through the metal or penetrating too much? (The weld on the upper right is the one I was trying to make tall, but had no luck)
Machine: EverLast 225LX
Tungsten: 3/32 sharpened to a point (2% Lanthanated)
Gas: 100% Argon @ ~15 cfh
Cup: #8 weld-craft cup with Gas Lens
Heatsink: 1/4" thick flat-bar of aluminum rests directly below the aluminum tubing
