er-ence of the welder. Some users claim that a lower rate of con-sumption and a softer weld is obtained from the latter. The size isdetermined entirely by the current to be used and varies from ^4tapered to j4 for currents of 50-150 amperes on light work, to1/4 tapered to ^/g for 800-1000 amperes… … Boundary between plate and weld. Note coarsened grain of plate stock. X/S- As the positive terminal of an arc attains a much higher tem-perature than the negative the metal to be welded is usually madepositive.
