An engine driven welding machine in which a welding generator is driven by an engine, and the aforesaid engine performs an idle operation when a welding operation is stopped is characterized by including an engine stop signal forming circuit IT which forms a stop signal for stopping an operation of the aforesaid engine when time of the aforesaid idle operation exceeds a predetermined time, a direct-current power supply PS connected to an output terminal of the aforesaid welding machine, voltage detecting means VS which detects a voltage change of the aforesaid output terminal, a restart detecting circuit RS which forms a restart signal for restarting the aforesaid engine when the detected voltage by the aforesaid voltage detecting means shows a predetermined change mode for starting the welding operation, and an engine control circuit EC which stops the aforesaid engine in response to the aforesaid stop signal, and restarts the aforesaid engine in response to the aforesaid restart signal. | 12-18-2008 |
| 20100032419 | WELDING GAN DRIVING DEVICE - A welding gun driving device is provided with an electric motor, a feed screw mechanism, and a pressure rod axially moved forward and backward via the feed screw mechanism by the electric motor. A rotor of the electric motor is formed into a hollow shape through which the pressure rod is insertable. The feed screw mechanism is provided with a screw shaft fixed to the rotor concentrically with the rotor, and a nut portion screwed to the screw shaft. The pressure rod is provided with the nut portion and a hollow rod portion extending toward the axial front from the nut portion. The rotor is provided, at its inner peripheral face, with a guide portion through which the pressure rod is inserted and supported so as to be relatively rotatable and axially slidable. | 02-11-2010 |
| 20140332516 | POWER SOURCE WITH RECHARGEABLE ENERGY STORAGE DEVICE - The present invention is directed to a welding-type power source that includes a power source housing and an engine arranged in the power source housing to supply electrical power. An energy storage device is included that is in rechargeable association with the internal combustion engine and arranged to provide welding-type power for at least a given period. | 11-13-2014 |
| 20150069035 | TIRE INFLATION SYSTEM FOR ENGINE DRIVEN WELDER - The invention described herein generally pertains to a system and method for an air compressor system integrated into an engine welder. In particular, an air compressor system can be powered by at least a motor of an engine driven welder such that the engine driven welder can provide enhanced capabilities related to use of stored compressed air. The air compressor system can be stored into a portion of a housing of the engine driven welder, wherein the housing is a compartment that allows for concealment of the air compressor system unless needed by a user. The stored compressed air can be utilized, for instance, to drive a pneumatic device or inflate a tire. | 03-12-2015 |
| 20150069036 | LIGHT SYSTEM FOR ENGINE DRIVEN WELDER - The invention described herein generally pertains to a system and method for including an illumination system with an engine driven welding device. In particular, an engine driven welding device can include a power source such as a motor and/or an energy storage device that can be utilized to power an illumination system that provides lighting and/or illumination to an environment via at least one lighting element. | 03-12-2015 |
| 20150069037 | ALTERNATIVE POWER FOR ENGINE DRIVEN WELDER - The invention described herein generally pertains to a system and method for a welding device and, in particular, a hybrid welding device, that leverages a renewable energy source for a source of electrical current. The welding device can include one or more renewable energy kits that harvest renewable energy sources for performing a welding operation or a powering at least one of a device or component external to the welding device. The welding device includes renewable energy component that collects an input to convert to an electrical current that can be used as a replacement current, a supplemental current, or a complimentary current. | 03-12-2015 |
| 20150069038 | BI-DIRECTIONAL ENERGY SHARING FOR ENGINE DRIVEN WELDER - The invention described herein generally pertains to a system and method for utilizing a power source of an engine driven welder as a portion of a power supply for a hydraulic device associated with a vehicle. The hydraulic device can be incorporated into a vehicle, a stand-alone device, or a combination thereof. One or more controllers can manage power distribution and identify power sources for the hydraulic device based upon a parameter. | 03-12-2015 |
