    摘要： A remotely operable welding machine controller device for controlling a power output of an arc welding machine includes a housing and a remote control. A potentiometer and a power supply are attached to the housing. A motor is operationally engaged to a slider of the potentiometer and is positioned to selectively motivate the slider along turns of a resistance wire of the potentiometer to adjust a magnitude of current in a circuit in which the resistance wire is included. A power cord is attached to and extends from the housing. The power cord is electrically engaged to the potentiometer and operationally engages the potentiometer to a source of alternating current. The power supply is operationally engaged to the motor to selectively power the motor. The remote control is communicatively engaged to the motor is manipulatable by a user to selectively actuate the motor.

    摘要： An arc welding apparatus and corresponding method includes a torch, a non-consumable electrode and a consumable electrode both disposed within the torch, a wire feeder configured to feed the consumable electrode in a vicinity of the non-consumable electrode, a first power source and a second power source that provide independent current, respectively, to the non-consumable electrode and the consumable electrode, and a weld process controller to control outputs of the first power source and the second power source such that a concentrated arc is formed, as a heat source, between the non-consumable electrode and a workpiece, and an inter-electrode arc is formed between the consumable electrode and the non-consumable electrode to melt the consumable electrode. The approach is characterized by low heat input, low distortion, low spatter, and the relative high speed or high deposition of laser and laser-MIG hybrid and other forms of multi-wire/multi-electrode welding, cladding, and additive manufacturing.

    摘要： Embodiments of hybrid engine welding systems are disclosed. One embodiment includes an engine, a generator, and a first disconnect device to mechanically couple/decouple the engine to/from the generator. A compressor produces a compressed air flow and/or a pump produces a hydraulic pressure. A second disconnect device mechanically couples/decouples the generator to/from the compressor and/or the pump. Electronics operatively connects the generator to a battery. The battery and the electronics power the generator as a motor at variable speeds when the generator is decoupled from the engine and coupled to the compressor or the pump, allowing selectable varying of a magnitude of the compressed air flow and/or the hydraulic pressure.
