<p>An electrostatic charging potential generator for a coating dispenser is useful with, for example, hand-held dispensers where the dispenser can be brought into closely spaced orientation with articles to be coated, or «targets». The generator of the disclosure incorporates a «fold-back» voltage-current characteristic including a reduced voltage-reduced current curve region in which the energy available at the dispenser is less than that necessary for spark ignition of solvents, atomized coating material particles, and the like suspended in the atmosphere around the dispenser.</p> |
