摘要： The present invention is directed to an overvoltage protection control that includes a combination of hardware and software that together detect and determine an average voltage of a power signal being supplied by a power source to a welding-type device. The determined average voltage is then compared to a “trip” voltage. If the average voltage is greater than or equal to the trip voltage then the welding-type device is disabled. The present invention may also be implemented as an undervoltage control wherein the detected average voltage is compared to a minimum acceptable average voltage. If the average voltage of the power signal being supplied to the welding-type device is less than the minimum acceptable average voltage, the welding-type device is prevented from being operated.

摘要： A multiple punch and multiple die assembly has a workpiece protector comprising a punch lifter that is operatively associated with each punch for supporting each of the punches in an inactive position as an active punch is moved by the ram to the active, i.e. operating position to thereby eliminate scoring or marking of the sheet material or other workpiece that is being punched. To eliminate the need for hand tools and hand assembly or disassembly, a manually moveable retainer on the punch assembly is provided that can be moved by hand between a punch-releasing and punch-retaining position for holding the punches within the multi-punch assembly during operation. To prevent stress fractures that formerly occurred in die carriers, support of each die is distributed between two different die components thereby reducing impact stress on the carrier as the ram drives the punch through the workpiece.

摘要： A power supply, such as a plasma cutting power supply or a welding power supply, that provides an output to a pair of output terminals is disclosed. The power supply includes a source of voltage and a plurality of choppers. The choppers are connected in parallel between the voltage source output terminals. A controller controls the choppers so that they are out-of-phase with respect to each of the other of the plurality of choppers. The choppers preferably include a freewheeling diode, an inductor and a switch. The number of choppers is approximately equal to the ratio of the open circuit voltage to the output load voltage.
