AtomArc® 10018-MM electrodes are used to weld low-alloy, high-tensile steels where welds of 100 ksi (690 MPa) minimum tensile strength is required. This electrode is recommended for use in the weld repair and fabrication of Mn-Mo steel castings and armor plate

• Medium penetration
• Moisture resistant coatings are incorporated in all AtomArc® electrodes
• The flux coatings are manufactured to effectively resist moisture pick-up in opened containers
• The improved coating provides an extra degree of reliability, especially for electrodes exposed to high humidity environments
• 2.6 lb/hr at 120 amp, 2.7 lb/hr at 140 amp deposition rate, 71.6% at 120 amp, 70.9% at 140 amp efficiency
• Flat, horizontal, vertical up, overhead welding positions
