A welding system includes a first sensor associated with a welding helmet and configured to sense a parameter indicative of a position of a welding torch relative to the welding helmet. The travel speed sensing system also includes a processing system communicatively coupled to the first sensor and configured to determine a position of the welding torch relative to a workpiece based on the sensed first parameter.

Helmet-integrated weld travel speed sensing system and method

A travel speed sensing system includes an optical sensor configured to be coupled to a welding torch. The optical sensor is configured to sense light incident on the optical sensor, and the travel speed sensing system is configured to determine a travel speed of the welding torch, a direction of the welding torch, or both, based on the sensed light.

Mountable sheet product dispenser

A welding system monitors the changes in the power output provided from a power supply to a device to determine the inductance of power cables between the power supply and the device. The device may determine the inductance of the power cables based at least in part on a delay in a threshold change in voltage to the device after a change in the current demand of the device, a delay in the initialization of the change in the current demand of the device after an initialization signal, a rate of change of the current drawn by the device, or a relative comparison of the voltage to the device and the current drawn by the device, or any combination thereof. If the inductance of the power cables is greater than a threshold inductance, the device may signal the user, disable operation of the device, or any combination thereof.

Some example product dispensers that accommodate two full paper towel rolls are provided herein. The product dispenser may employ separate dispensing mechanisms for each product roll and may include roll holders that articulate out from the housing to facilitate easy loading and access to replacement and loading of the other product roll. A roll partition may be utilized to separate the web paths of the two product rolls and enable rotation of front roll holders. Example funnel covers and nip covers can aid with intuitive installation. Example roll holders with retention mechanisms help prevent unintentional dropping of the installed product roll. Other beneficial features include utilizing motor operation sensing to dispense a desired sheet length, automatic/assisted loading into the dispensing mechanism, automatic switching between dispensing of product rolls, and always dispensing from the smaller product roll first. Many other features/structures of example product dispensers are also described herein.

A welding helmet for detecting arc data is provided. One embodiment of the welding helmet includes an arc detection system configured to detect one or more welding arcs that occur during one or more welding operations. The welding helmet also includes control circuitry configured to count a number of the one or more welding arcs detected by the arc detection system. The welding helmet includes a storage device configured to store the number of the one or more welding arcs.

Welding systems including welding torch assemblies are provided. The welding torch assembly may include a welding torch adapted to be utilized in a welding operation to establish a welding arc between the welding torch and a workpiece. Shielding gas may be supplied to the welding torch for establishment of a gas shielding area around a weld pool. The welding torch assembly may also include a temperature sensing system having a non-contact temperature sensor coupled to the welding torch and adapted to sense a temperature of the workpiece at a location outside of the molten weld pool.

Welding systems having non-contact temperature measurement systems

A main controller may be used to provide integrated, centralized, and optimized handling of telematics data in welding arrangements. The main controller may receive from other components of a welding arrangement, telematics data, and may apply at least some processing to the telematics data, to enable use of the telematics data by a remote entity. The telematics data may comprises data relating to an engine used in driving one or more components of the welding arrangement, data relating to one or more components of the welding arrangement, and/or data relating to welding operations performed via the welding arrangement. The processing of telematics data may comprise formatting data in accordance with a single standard format, digitizing analog data, and/or processing data for communication to the remote entity. The main controller may provide telematics client and/or host node functions, such as based on the controller area network (CANBus) protocol.

In one aspect, a protective headwear is provided and includes a support member configured to engage a user's head, an outer shell coupled to the support member and rotatable relative to the support member between a first position and a second position, and a member coupled between the support member and the outer shell to reduce angular velocity of the outer shell as it moves from the first position to the second position. In one aspect, the protective headwear is a welding helmet.

Apparatus for reducing angular velocity of protective shells associated with protective headwear

System for determining inductance of a power cable

A welding training system includes a welding training software having a first training mode configured to simulate a welding arc and a second training mode configured to use a live welding arc. The welding training system is configured to block welding power flow between a welding power supply and a welding torch while the welding training software is in the first training mode. The welding training system is also configured to enable the welding power to flow between the welding power supply and the welding torch while the welding training software is in the second training mode.
