With aluminum you want minimum stick out and a small cup not too much gas either caise itll create a vac and suck oxygen into the weld zone.I figured out my problem, ive noticed that when my stickout is to high and my torch angle is >90 deg I have problems. When I decreased stickout and kept the torque relatively vertical my problems went away.
