This video shows lots of beads during an exercise I call "the aluminum drill".
In sports, there are drills designed to improve certain skills.
Because Aluminum requires so much more feeding of the wire than steel, this drill will help that filler wire feeding hand to get up to speed.
The basic settings are 100-140 amps using foot pedal so basically what that mean is at times I am at 140 amps but also much lower when heat soaks the small practice piece.
i used nearly 140 amps but when the aluminum gets soaked with heat, I used the foot pedal to use less amperage.
