Welding Wire, Diameter 0.035 in, Wire Type Flux Core, Material Carbon Steel, AWS Classification E71T-11, Container Size 33 lb, Container Type Spool, Method FCAW, Series, Applications With Copper Back-Up, Plate Thicknesses In The Range Of 7.9 mm (5/16 in) To 12.7 mm (1/2 in), Propane Cylinders And Robotics/Hard Automation, Sheet Or Thin Gauge Metal Application. E6011 electrodes can also be used for any-position welding using a alternating current (AC) welding power source. Like E6010 electrodes, E6011 electrodes produce a deep, penetrating arc that cuts through corroded or unclean metals. Many welders choose E6011 electrodes for maintenance and repair work when a DC power source is unavailable.
