A welding system can manage wire feeders such that unused wire feeders are conveniently stowed. The welding system include two or more wire feeders individually attachable to a welding torch. The welding system includes one or more mount points to secure unused wire feeders and enable convenient swapping of an active wire feeder.

Wire management for a welding system

A mobile welding system that does not rely exclusively on a track to define the path of the welder. One embodiment includes a mobile welder adapted to move along a work piece. The mobile welder includes a chassis, including a welding implement, and a travel assembly configured to support the chassis over a portion of the work piece. The mobile welder also includes a motor assembly configured to selectively cause the chassis to move relative to the work piece. The mobile welder further includes a chassis holder, having a magnet assembly, configured to provide a force holding the chassis a selected distance from the work piece. The magnet assembly includes a magnet rotatably mounted between a ferrous material and a non-ferrous material to selectively control application of a magnetic field toward the work piece.

Mobile welding system

An electric arc welder and a method for performing a pulse welding process producing reduced spatter. The welder produces a current between an advancing electrode and a workpiece. The welder includes a short-detecting capability for detecting a short condition upon occurrence of a short circuit between the advancing electrode and the workpiece. The welder may also include a switching module in the welding circuit path of the welder having an electrical switch and a resistive path. Times of occurrence of short intervals can be tracked and a blanking signal can be generated based on the tracked short intervals to anticipate a next short interval in a next pulse period of the pulsed welding process. The blanking signal can be used to reduce a welding current in the welding circuit path by introducing additional resistance into the welding circuit path via the switching module, for example.

Method to control an arc welding system to reduce spatter

The invention described herein generally pertains to a system and method related to controlling a welding system having a tractor welder engaged with a track by utilizing a pendant component that is configured to receive an input from a user and displaying data via a graphical display. The pendant component includes one or more inputs that correspond to data displayed, wherein the one or more inputs include a first toggle switch and a second toggle switch, an encoder knob, a first set of buttons and a second set of buttons.

A mobile welding system that does not rely exclusively on a track to define the path of the welder. The present invention generally provides a mobile welder adapted to move along a work piece, the mobile welder including a chassis supporting a motor assembly; a travel assembly attached to the chassis and adapted to support the chassis over a portion of the work piece, wherein the motor is coupled to the travel assembly to selectively cause the chassis to move relative to the work piece; a controller connected to the motor assembly to control movement of the chassis relative to the work piece; a chassis holder connected to the chassis, the chassis holder being adapted to provide a force holding the chassis a selected distance from the work piece; and a welder supported on the chassis, the welder including an implement adapted to perform a welding operation, wherein the implement is supported on the chassis at a location where the implement and the chassis define an uninterrupted line of sight from the implement to the work piece, wherein the chassis holder is spaced from the line of sight a distance sufficient to prevent the chassis holder from interfering with the welding operation.

The invention described herein generally pertains to a system and method related to influencing a direction of an arc within a welding operation. Within a hot wire welding operation, an arc is generated between an electrode and a workpiece and a welding wire is energized while being supplied to a puddle formed by the electrode in order to deposit the liquefied welding wire onto the workpiece. A welder system and/or method is provided that controls a direction of the arc based on at least one of a polarity of the welding wire (via a power supply that energizes the welding wire), a location of the welding wire in proximity to the arc, a synchronization and/or de-synchronization of a polarity of the welding wire with the electrode, an activation and/or a de-activation of energizing of the welding wire, or a combination thereof.

System and method for hot wire arc steering

A welding system is disclosed that includes a power supply, a controller in communication with the power supply, and a welder in communication with the controller. The controller detects a configuration of the welder that includes at least a 1G configuration. Upon the controller detecting the 1G configuration, the controller inverts a height adjustment and automatically calculates a contact tip to work distance.

Welding system

A system and method of welding is provided where a pulse welding power supply is coupled with a magnetic field power supply such that a magnetic field can be generated proximate to a welding arc during pulse welding. During pulse welding a magnetic field is used to direct the welding arc and a droplet being transferred in the arc.

Synchronized magnetic arc steering and welding

An arc welding system includes a welding torch, an electrode, and a power supply having a switching-type power converter connected to the torch. A parallel state-based controller is connected to the power converter and provides a waveform control signal thereto for controlling its operations. The controller generates a motion control signal for controlling movements of the electrode and/or the torch. A sensor senses welding voltage or welding current. A memory stores a welding state table comprising sequential control states, and stores a motion control system state table comprising further sequential control states. The welding waveform is defined in the welding state table. The controller controls the operations of the power converter through the waveform control signal according to the welding state table, simultaneously adjusting the motion control signal according to the motion control system state table. The controller transitions between control states according to the signal received from the sensor.

Parallel state-based controller for a welding power supply

The invention described herein generally pertains to a system and method related to detecting a change in height during a welding operation and adjusting one or more welding parameters based on such detected change in height. In particular, a change in a height can be related to two or more revolutions on the workpiece in which the change is due to material being deposited onto the workpiece from the welding operation. Since the material deposited onto the workpiece changes the height of the electrode to the workpiece, one or more welding parameters can be adjusted for compensation. Specifically, an electrode speed can be adjusted to compensate for a change in the height, wherein the electrode speed is a rate that the electrode moves adjacent to the workpiece.

System and method for true electrode speed

A welding helmet is capable of providing an image representative of information from an associated welding operation where the image appears in the same focal range as the welding work area.

The control unit outputs a feedback signal corresponding to the monitoring. The control unit also includes a comparison circuit that compares the feedback signal with at least one predetermined value corresponding to a position of at least one of the arc and the torch head in the weld groove. The control unit further includes an arc steering system that outputs a steering signal based on the comparison.
