摘要： An operating system is provided for an electric arc welder including a high switching speed inverter power source for creating an arc voltage and arc current between an electrode and a workpiece. This operating system regulating the arc voltage to provide a voltage with a slope by using an error circuit to create an error output and having a first input with a signal representing the set voltage and a second input representing the sum of the actual arc voltage and the actual arc current multiplied by a slope constant. A DSP program reduces the error output by adjusting the voltage output of the inverter power source to change the actual arc voltage. The slope constant is in the range of 0–10%.

摘要： An electric arc welder for depositing weld metal along a groove between two edges of a metal workpiece where the welder comprises a first electrode driven by a first wire feeder toward a point in said groove, a second electrode driven by a second wire feeder toward the point and a main power source with a first output terminal connected to the first electrode and a second output terminal connected both to the second electrode and directly or indirectly to the metal workpiece to create a second electrode path and a workpiece path. The power source includes a high speed switching output stage for creating current with a selected AC waveform between the first and second output terminals where the waveform of the main power source is generated by a waveform generator controlling a pulse width modulator circuit to determine the current operation of the output stage.

摘要： An electric arc welder for depositing weld metal along a groove between two edges of a metal workpiece. The welder comprises: a leading electrode driven toward a point in the groove by a first wire feeder operated at a first speed by a first motor with a speed control input and a tachometer derived first feedback signal, a trailing electrode driven toward the same point by a second wire feeder operated at a second speed by a second motor with a speed control input and a tachometer derived second feedback signal, a first power source directing a first current to flow through the leading electrode and a second power source causing a second current to flow through the trailing electrode with the current flow being in a series arc circuit. The second power source being grounded to the workpiece to modify the series arc current so ground current flows to the workpiece whereby the second current is generally equal to the first current minus the ground current.

摘要： A machine including an engine cooling system, a secondary system with a low-temperature limit, and a secondary cooling system. A temperature sensor is associated with the secondary cooling system. The temperature sensor senses the secondary cooling system temperature and provides a temperature signal. A control valve has an open position allowing fluid communication between the engine cooling system and the secondary cooling system, and a closed position disallowing fluid communication. A controller receives signals from the secondary system temperature sensor and commands the control valve to open when the secondary cooling system temperature is below the low-temperature limit.
