摘要： Systems and method for a welding-type power supply (8100) to provide both a welding output voltage and a battery charging output voltage. The power supply (100) includes a first contactor (W2-W4) associated with a first circuit to provide the welding output voltage, and a second contactor (W1) associated with a second circuit to provide the battery charging output voltage. An auxiliary switch (SW1) is operatively coupled to the second contactor (W1), to prevent the first circuit from closing when the second contactor is closed to prevent transmission of the welding output voltage to the second circuit.

摘要： A hybrid welding system is provided. In one embodiment, the welding system includes an engine-driven generator, an energy storage device, a contactor, and a controller. The controller may be configured to control delivery of weld power from the generator when a commanded output is below a threshold level, and from both the generator and the energy storage when the commanded output is above the threshold level. Closing of the contactor enables the energy storage device to contribute to weld power during welding operations and to be charged by the generator output independent of charging between weld operations. Additional hybrid welding systems and methods are also disclosed.

摘要： A TIG welding power source (100) for providing controlled AC arc welding processes is provided. In the AC TIG arc welding power source (100) embodiments, configurations of main and auxiliary bridge circuits (160, 170) allow for the directional switching of the output welding current through the welding output circuit path and selectively provide one or more high impedance paths to rapidly decay the arc current. The high impedance path aids in the low spatter transfer of molten metal balls from consumable to a workpiece (W), via an arc generated by a tungsten electrode (E), and further aids in the maintaining or the re-establishing of an arc between the tungsten electrode (E) and the workpiece (W) during welding.
摘要翻译：提供了一种用于提供受控AC电弧焊接工艺的TIG焊接电源（100）。在AC TIG弧焊电源（100）实施例中，主桥电路（160,170）的配置允许输出焊接电流通过焊接输出电路路径的方向切换，并选择性地提供一个或多个高阻抗路径快速衰减电弧电流。高阻抗路径有助于通过由钨电极（E）产生的电弧将熔融金属球从可消耗的材料到工件（W）的低飞溅转移，并且还有助于维持或重新建立电弧钨电极（E）和工件（W）。

摘要： The invention relates to a method for the connection of several current sources, in particular several welding devices (1; 27; 28), plasma jet sources or similar. In independent individual operation a process control and/or regulation device (4; 31; 32) in each welding device (1; 27; 28) transmits set values to a U/I controller for a power component (3; 29; 30). The power component (3; 29; 30) supplies a user, connected to output sockets (38, 39; 40, 41; 42, 43), with energy corresponding to the set values. According to the invention, several welding devices (1, 27, 28) of the same and/or different output, or similar and/or different machine ratings are connected together on the secondary side, by means of the output sockets (38 to 43) to give a welding device (1, 27, 28) with physically greater output. In order to control the connected welding devices (1, 27, 28), the above are connected to each other by means of a proprietary digital interface (44, 45, 46) and/or a particular digital connection interface (47, 48, 49) for a data exchange therebetween. A process control and/or regulation device (4, 32, 33) for a welding device (1, 27, 28) assumes process control for all further connected welding devices (1; 27; 28).

摘要： A cage system for laboratory animal care has a plastic cage with a removable suspended perforated-bottom, a snap-on plenum cage top and a cage top feeder lid. The removable floor of the cage has perforations that allow both liquid and liquid waste down to the cage bottom. Bedding is placed on top the suspended floor. A filtered air supply is introduced into the wall of the cage below the suspended floor and flows upward through the suspended floor through the cage in a laminar fashion and passes through orifices in the bottom of the lid and out through the filtered opening in the top. A water supply system for the cage is provided. The system is air tight and air in any one cage is isolated from air in all other cages in the system which can be mounted on a rack. Liquids drain out of the cage body possible into the plenums. A plurality of cages are supported in a rack. Several configurations to support the cage within the rack are provided.
