rent density used.While smaller electrodes cannot successfully conducthigh currents, they are able, at a certain point, to main-tain high current density. A point is reached at whichsmall electrodes sustaining high current densities yieldhigher deposition rates than larger electrodes withlower current density. For this reason, other weldingprocesses that utilize a continuous wire feeder oftenrender greater productivity. They use an electrode thatis much smaller in diameter, which can sustain muchhigher current density than shielded metal arc weldingelectrodes
