Mac Trode E6630
AWS E630-16
Descriptions & Applications:
Low hydrogen manual metal arc electrode using a silicon free, low carbon, high purity, C:Mn core wire with a concentrically extruded, moisture resistant rutile flux, with a recovery rate of approximately 130% with respect to core wire. Easy to strike electrode which produces porosity free weld deposits.
