  • Patent number: 11376642
    Abstract: Fume evacuation systems are disclosed. An example fume evacuation system includes: an air handling system for drawing components comprising air, fumes, smoke, or particulate, or a combination thereof from a metal working application; an air conduit couple to the air handling system for conveying the components from the metal working application towards the air handling system; and a hood coupled to the air conduit and configured to be positioned at the metal working application, the hood comprising a structure defining a circuitous path for particulate that, in operation, allows the airborne components to pass through the hood to the air conduit but causes particulate to cool the components.

  • Patent number: 11027356
    Abstract: An engine-driven welder generator is controlled based upon power draw for welding and other applications. Once a welding arc is initiated, the power draw is monitored. The engine speed, and therefore the power output of the generator, may be increased or maintained based upon the power draw. The power draw may include both welding power draw and auxiliary power draw. The engine speed is increased in increments. The initial engine speed and subsequent increments may depend upon particular welding processes or regimes.

  • Patent number: 9902008
    Abstract: A method includes detecting whether a wire feeder is in communication with a welding power supply. The method also includes detecting a current welding process of the welding power supply if the wire feeder is in communication with the welding power supply. The method includes determining, at the wire feeder, a welding output polarity. The method also includes setting a new welding process based on the current welding process and the welding output polarity without a user selecting the new welding process.

  • Patent number: 9839948
    Abstract: A fume evacuation system is designed to remove smoke, fumes, and particulate from a metal-working or other application. The system may include a cart-type base unit or may be incorporated into a fixed or semi-fixed installation that uses suction to draw air (e.g., containing smoke, fumes, and particulate) away from the metal-working application. The fume evacuation system includes a hood that creates an arduous flow path and varying velocity profile, which cools and separates any particulate matter in the suctioned air. The arduous flow path may include multiple sharp turns created by an inner deflector component and an inlet tube. The inlet tube may further contain baffles to cool particulates from the suctioned air.
