U.S. Air Force Airman 1st Class Elfie Diltz, a 35th Maintenance Squadron aircraft metals technology technician, turns a wire speed dial at Misawa Air Base, Japan, Feb. 1, 2017. The dial controls how fast it feeds metal into a CP-300 gas metal arc welder, providing extra material to bind other parts together. The flight repairs metal for the F-16 Fighting Falcon, ensuring its power projection across the Indo-Asian Pacific region. (U.S. Air Force photo by Airman 1st Class Sadie Colbert)
