ESAB Atom Arc 12018 Electrode - 3/32" X 14" - 50 lb HS - 255107336

Atom Arc 12018 is recommended for use in fabrication of low-alloy, high tensile steels where welds of 120 ksi (830 MPa) minimum tensile strength are required. Atom Arc 12018 is typically used to weld forging, casting plate and pressure vessels.

Preheat should be used on hardenable steels to prevent the formation of a hard heat-affected zone. Preheat may also be required in welding heavy section
