A mixture of phases whose composition are determined by the eutectoid point in the solid region of an equilibrium diagram and whose constituents are formed by eutectoid reaction.

Alloy of a composition that solidifies at a lower temperature than the individual elements of the alloy and freezes or solidifies at a constant temperature to form a fine mixture crystals made up of two or more phases.

When the arc or burn-off characteristics are not smooth and difficult to handle. Can?t control where the puddle goes.
