Abstract
A system and method of rating the arc maintainability of an electric arc welding stick electrode by creating an arc between the electrode and a workpiece; moving the electrode along the workpiece while maintaining the arc; decreasing either the current or the voltage until a point is reached where the arc is extinguished; determining the open circuit voltage at the point; and, rating the electrode based upon at least the open circuit voltage point.
