This electromotive force is negative for low value of current, however above about 25a it increases more or less in proportion to current. Depending upon the net force acting on the droplet in the light of the magnitude of welding current, surface tension, drag force, the role of gravity, and the arc length a particular mode of metal transfer.
An electromotive force series (emf series) is a metal's ranking in respect to inherent reactivity. The metals located at the top of the series are considered the most noble, with the highest level of positive electrochemical potential. The metal that can be found at the bottom is the most active and contains the highest amount of negative electrochemical potential.
