Hobart® E9018-M H4R Hoballoy® 9018M Low Alloy Steel Electrode with 1/8" Dia uses AC or DCEP (Direct Current Electrode Positive) type current and is recommended for use in high tensile steels. It offers resistance to moisture reabsorption which helps prevent hydrogen cracking and aids in elimination of starting porosity. This is an outstanding welding electrode for higher strength steels with tensile strength in excess of 90000 psi. Coating is specifically formulated to resist moisture pick-up under conditions of high heat and humidity. It is best known for its good arc characteristics providing stable and easy to control arc while low smoke level offers welder safety and comfort. Quick and easy slag removal helps in reducing clean-up time. Low hydrogen less than 4 ml/100 g is resistant to hydrogen-induced cracking. If exposed to atmosphere for long periods electrode needs to be reconditioned for one hr at 600 deg F. After opening, store it in holding oven at 250 - 400 deg F until used. Electrode comes in a hermetically sealed container of 10 lb.
