The present invention comprises a lash prevention spring of unique design having a plurality of spring legs shaped into an s-curve and an inner circumference formed into at least one spline. The trim die includes a trim plate with a connected trim punch moveably mounted in a stripper plate. The method also includes flowing a gas mixture into the plasma processing chamber; energizing the ignition electrode at a strike frequency; and striking a plasma from the gas mixture with the ignition electrode. An L-shaped tongue extends into the receiving space. New fields can be added as needed for processes and materials. In one aspect, the system may be used to allocate limited power from a backup power source.
