  1. A spool gun or push-pull feeder ✔
  2. A longer standard liner
  3. Extra stickout

Why: Soft aluminum wire is like pushing a wet noodle. A spool gun or push-pull system feeds it a long distance without buckling.

Huh, didn't know that: Miller says aluminum pulls heat faster and wants to distribute it through the part.
