Soldering
Senior Airman Curtis Rosga, 62nd Maintenance Squadron avionics technician, solders new lights to the panel of a public address control May 13, 2013 at Joint Base Lewis-McChord, Wash. Avionics technicians troubleshoot faulty equipment, diagnose problems and repair them. By fixing faulty equipment in-house, the avionics flight helps save Air Force dollars by helping to eliminate the need to purchase replacement parts or having to send equipment to an outside source for repair.
