Lincoln Electric ED035417 UltraCore 111K3M-H Plus is a 0.045 in (1.1 mm) gas-shielded flux-cored wire (FCAW-G) on a 33 lb (15 kg) plastic spool, designed for high-strength, low-alloy applications where you need consistent arc performance, strong mechanical properties, and dependable all-position capability. It’s commonly selected for structural and heavy fabrication work where procedure control and toughness matter; confirm your WPS requirements (classification, shielding gas, and polarity) before use on code or critical weldments.
