A torque wrench having post-torque rotation setting and measurement function, optionally including auto transition from torque to angle rotation, which may operation with and without batteries, including low profile design, improved visual, audio and haptic feedback, a recesses pawl seat for improved accuracy and longevity and improved handle rotation for torque setting and spring unwinding by virtue of improved torque setting nut design.

Hybrid electromechanical torque wrench

A welding machine includes a main transformer having first primary winding, a second primary winding, and a secondary winding; a power board configured to receiving mains power and to convert the mains power to converted power to be input to the main transformer; a switch having an input connected to an output of the power board, a first output connected to the first primary winding of the main transformer, and a second output connected to the second primary winding of the main transformer; and a control board configured to control the switch to be arranged in one of (i) a first configuration in which the converted power is supplied, in series, to a first primary winding of a main transformer switching and a second primary winding of the main transformer, and (ii) a second configuration in which the converted power is supplied, in parallel, to the first primary winding of the main transformer and to the second primary winding of the main transformer.

Multi-process welding and cutting machine

Display screen or portion thereof with graphical user interface

A multi-process welding machine provides an intuitive user interface to enable a user to select among different welding processes, and to select parameters for a given selected welding process. The multi-process welding machine also provides an arrangement by which a switching module, or DC to AC converter, of an AC TIG unit can be controlled to alternatively supply AC or DC welding voltages or current. Further, a configuration of switches can be leveraged to automatically (or manually) control the polarity of welding cables for different processes and to engage or disengage a wire feeder when, e.g., a MIG welding process is selected, or not selected, respectively. Finally, in an embodiment, the ferrite or magnetic materials used for a main output inductor and an high frequency starting inductor of the welding machine can be combined.

Portable AC-DC multi-process welding and cutting machine

A system, computer-implemented method, and article for controlling a user interface of a portable welding system are described. An input signal receiver, operable on a processor, is configured to receive one or more input signals from one or more input devices. A display controller, operable on the processor, is configured to receive, input information based upon the one or more input signals. A display device is configured to display a user interface provided by the display controller, the user interface including a first portion including an adjustable value and a second portion including a non-adjustable value. The display controller is configured to highlight changes to the non-adjustable value based upon changes made using the one or more input devices to the adjustable value.

Techniques for controlling a portable welding system

Display screen with graphical user interface

A locating device disposable on a surface has a housing, a capacitance sensor, a radar sensor, and an inductance sensor. The locating device also has a motion sensor disposed for detecting at least one motion parameter. A controller receives data from the capacitance sensor, the radar sensor, the inductance sensor and the motion sensor, and determines from the data a presence of objects disposed within or behind the surface. A display is used for displaying a graphical representation of the objects disposed within or behind the surface.

Handheld locating device

An electronic torque wrench including a wrench body, a wrench head configured to engage a workpiece, a first sensor producing a first output signal, that is proportional to an amount of torque being applied to the workpiece, a grip handle, a second sensor producing a second output signal that is proportional to an amount of rotation being applied to the workpiece, a user interface including an input device for inputting a preset torque value, and a processor for converting the first output signal into a current torque value, comparing the current torque value to the preset torque value, and converting the second output signal into a first angle value through which the workpiece has been rotated after the current torque value exceeds the preset torque value.
