The E7018 AC Stick Welding Electrode produces high-quality results on low amperage DC welders and higher amperage AC welders. The electrodes are suitable for all positions on steel without preheating. Good on cold rolled steels without preheating. Good on cold rolled sheets that do not react well with a conventional rod. The low hydrogen content reduces cracking and peeling of the weld material. 3/32-Inch ie.2.38 mm diameter rod. 5-Pounds ie.2.26 kg. Tensile Strength 70,000 PSI Amperage 75-105 Amps DCEP Reverse or AC. Typical Spec Example E6011: E is for the electrode.
