    • A system and method are provided for controlling an internal combustion engine driving a generator/welder or a stand-alone generator. Controlling the engine may include altering the engine speed based upon a detected demand on the generator and/or operating parameters of a welder. For example, the engine speed may be increased based on a detected draw on the generator and/or the operating parameters of the welder. In addition, the engine speed may be automatically decreased to a non-standard idle speed or the engine may be automatically turned off if no demand is detected for a period of time. Additionally, the engine speed may be increased if only frequency-insensitive demands are detected on the generator. Combinations of these and further methods may be executed. Various devices are provided for implementing the above methods.
    • 提供了一种用于控制驱动发电机/焊机或独立发电机的内燃机的系统和方法。 控制发动机可以包括基于对发电机的检测到的需求和/或焊工的操作参数来改变发动机转速。 例如,可以基于发电机上的检测到的抽吸和/或焊接机的操作参数来增加发动机速度。 此外,发动机转速可以自动降低到非标准怠速,或者如果在一段时间内没有检测到需求,则发动机可以自动关闭。 此外,如果在发电机上仅检测到频率不敏感的需求,则可以增加发动机转速。 可以执行这些和其它方法的组合。 提供了用于实现上述方法的各种装置。

    • A technique is disclosed for controlling a constant current regime, such as for stick welding. The regime includes a dig segment or regime in which current is increased as voltage decreases. The dig regime is initiated at a voltage that can be set by an operator. The constant current regime also includes two distinct constant current segments separated by a transition segment. The transition segment occurs at a predetermined voltage, permitting rapid and predictable operation as an arc is lengthened during welding. The constant current segments may be suitable for different types of electrode. The dig selection also permits customizing the regime for soft or stiff digs that are initiated at different voltages (or arc lengths) suitable for different electrode types.
    • 公开了一种用于控制恒定电流状态的技术,例如用于棒焊。 该制度包括电压下降的电流增加的挖掘段或制度。 挖掘机制以可由操作员设定的电压启动。 恒定电流状态还包括由过渡段分隔的两个不同的恒定电流段。 过渡段发生在预定电压下,允许在焊接期间电弧延长时进行快速和可预测的操作。 恒流段可适用于不同类型的电极。 挖掘选择还允许定制适于不同电极类型的不同电压(或电弧长度)启动的软或刚性挖掘的方案。
