Stick Electrodes Lincoln Electric Conarc® 49C

Conarc® 49C Stick Electrode – Basic Welding Electrode for Unalloyed Steels (E7018-1)

The Conarc® 49C stick electrode is a high-quality basic-coated welding electrode for unalloyed steels, developed for safety-critical applications in steel, plant, and offshore construction. It offers very high impact toughness down to −40 °C, excellent CTOD values, and an extremely low hydrogen content, even where nickel alloys are not permitted.
