    Abstract: A wire electrode for use in arc welding comprising a metal to be deposited on a substrate and further comprising a flux, said flux comprising: 1. A magnesium-aluminum alloy having an aluminum content of 20 to 80 percent, said alloy present in said flux in the amount of 5 to 35 percent by weight; 2. Calcium fluoride present in said flux in the amount of 30 to 80 percent based on the weight of said flux; 3. Hematite present in said flux in an amount of 3 to 30 percent by weight; 4. Silica and/or manganese in an amount less than 10 percent based on the weight of said flux; 5. Titanium in an amount less than 1.00 percent, based upon the weight of said flux; 6. Zirconium present in said flux from 0.005 to 0.200 weight percent, based on the weight of said flux; and 7. Boron in an amount less than 0.060 weight percent, based upon the weight of said flux.

    Abstract: A raw material distribution chute is rotated when inner and outer cylinders are rotated in unison, and is tilted when the inner or outer cylinder is vertically moved with respect to the outer or inner cylinder. The rotation and tilting of the distribution chute may be made simultaneously or individually so that the pattern of raw material distribution may be varied over a wide range.
