Hobart® E8018-B2 H4R Hoballoy® 8018B2 Low Alloy Steel Electrode with 1/8" Dia uses AC or DCEP (Direct Current Electrode Positive) type current and is recommended for use in boiler fabrication and maintenance. Outstanding welding electrode for higher strength steels with tensile strengths greater than 80000 lb is definitely a preferred electrode with high operator appeal. The coating is specially 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. Low hydrogen less than 4 ml/100 g is resistant to hydrogen-induced cracking. Quick and easy slag removal helps in reducing clean-up time. Electrode measuring 14" offers resistance to moisture reabsorption which helps prevent hydrogen cracking and aids in elimination of starting porosity. 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 220 deg F - 350 deg F until used. Electrode comes in a hermetically sealed container of 50 lb.
