    摘要: A welding machine that includes a power supply having at least one control input is described. The power supply is capable of providing an electrode positive and an electrode negative output. Also, the magnitude and balance of the output is controllable. The machine includes a controller that controls the power supply. If the user selects an electrode negative output the controller causes the output to be electrode positive at at least a first magnitude for a predetermined period of time at the start of the welding process. Then, the controller causes the output to be electrode negative at a magnitude equal to or greater than a second magnitude. Thereafter, the controller causes the output to be a user selected magnitude. If the user selects an ac mode, the electrode positive portion of the output is not constantly responsive to at least one of the user selected frequency and the user selected balance.

    摘要: A welding power supply includes an input rectifier that receives sinusoidal or alternating line voltage and provides a rectified voltage. A pre-regulator provides a dc bus and a convertor, such as a boost convertor, provided a welding output. The pre-regulator is an SVT (slow voltage transition) and an SCT (slow current transition) switched convertor. It may include a snubber circuit having a diode that is SVT switched. Also, the boost convertor may be SVT and SCT switched. The pre-regulator preferably includes a power factor correction circuit. The power source includes, in one embodiment, an inverter having a snubber circuit having a first switch in anti-parallel with a first diode, and a second switch in anti-parallel with a second diode. The first switch and first diode are connected in series with the second switch and the second diode, and the first and second switches are connected in opposing directions, to form a switched snubber.

A method for selecting one of a plurality of input voltages by moving first and second links is also described. The power supply includes a housing and the links are inside the housing. The links configure the power supply to receive a selected input voltage from a number of input voltages, depending upon the position they are in. The links depend on one another. Indicators are connected to the links, and show for what input voltage the links are connected. The indicators are visible from outside the housing. The housing includes one or more windows through which the indicators are visible. The indicators are alpha-numeric characters or drawings. The links includes a circuit board with the indicators mounted thereon and a plug or a set of copper bars that are placed in either the first or second position.

    摘要: A method and apparatus for welding power includes an input rectifier, a pre-regulator, a convertor, an auxiliary voltage circuit and a controller. The pre-regulator is connected to receive a rectified voltage and provides a dc bus. The convertor converts the bus to a welding output. The auxiliary voltage circuit is connected across the welding output, in parallel with the converter. The controller shuts the converter down in the event an open circuit condition exists at the output, thus providing a safer open circuit voltage.

    摘要: A method and apparatus for providing welding type power is disclosed. The power source is capable of receiving any input voltage over a wide range of input voltages and includes an input rectifier that rectifies the ac input into a dc signal. A dc voltage stage converts the dc signal to a desired dc voltage and an inverter inverts the dc signal into a second ac signal. An output transformer receives the second ac signal and provides a third ac signal that has a current magnitude suitable for welding, cutting or induction heating. The welding type current may be rectified and smoothed by an output inductor and an output rectifier. A controller provides control signals to the inverter and a controller power supply can also receive a range of input voltages and provide a control power signal to the controller, and a voltage independent of the input voltage.
