摘要： A "hot start" method for arc welding includes selecting a first weld current, setting a time interval, striking an arc, flowing a second, higher weld current through the welding rod and then, after a brief time interval, reducing the current through the rod to the value of the first weld current. Also disclosed is a new arc welder stator having two groups of slots around a core. The group of larger slots contains the weld current windings and slots in the group of smaller slots contain windings for timing, gate voltage, battery charging, auxiliary power and the like. A new cooling apparatus for an arc welder has an air duct and a "double-bladed" fan for flowing air along several paths and cooling both the welder control section and the generating section. A new method for electronically controlling engine speed in an engine-driven arc welder is also disclosed. Such method includes manipulating a current-selecting device, contacting a work piece with a welding rod, accelerating the engine to an elevated speed and then either maintaining such speed or reducing it, depending upon the value of weld current selected.

摘要： Disclosed is an automatic transfer switch (ATS) having "operate," "test" and "isolate" positions for the switch per se. A handle selects one of the positions and a mechanical linkage couples the ATS and the handle to one another. In the improvement, the linkage has first and second members for applying motive force to the switch. The mechanical linkage has first and second rotary driver devices in engagement with the first and second members, respectively, thereby providing redundant switch-positioning mechanisms. The new ATS may be combined with a bypass switch having "normal," "auto" and "emergency" contact positions. A switch interlock linkage extends between the transfer switch and the bypass switch and includes a bypass plate and a transfer plate coupled to one another by a bar. The bypass switch includes a pivot-mounted first bypass interlock member obstructing substantial movement of the bypass plate when the bypass switch electrical contacts are in the "normal" position. And the transfer switch includes a pivot-mounted first transfer interlock member obstructing substantial movement of the transfer plate when the transfer switch electrical contacts are in the "emergency" position.
摘要翻译：公开了一种具有用于开关本身的“操作”，“测试”和“隔离”位置的自动转换开关（ATS）。手柄选择一个位置，机械连杆将ATS和手柄彼此连接起来。在改进中，连杆具有用于向开关施加动力的第一和第二构件。机械联动装置具有分别与第一和第二构件接合的第一和第二旋转驱动装置，从而提供冗余的开关定位机构。新的ATS可以与具有“正常”，“自动”和“紧急”联系位置的旁路开关组合。开关互锁联动装置在转换开关和旁路开关之间延伸，并且包括旁路板和通过杆彼此连接的转印板。旁路开关包括枢轴安装的第一旁路互锁构件，当旁路开关电触点处于“正常”位置时，阻挡旁路板的实质运动。并且转印开关包括枢转安装的第一转印互锁构件，当转印开关电触点处于“紧急”位置时，阻挡转印板的实际运动。
