Connection boxes for gas tungsten arc welding (GTAW) training systems are described. In some examples, a connection box of the GTAW training system coordinates delivery of welding-type power to a GTAW torch during training. In some examples, a remote control (e.g., foot pedal) may be activated at different levels to command different levels of welding-type power be delivered to the GTAW torch from a welding-type power supply. In some examples, the connection box may selectively enable or disable communication between the remote control and welding-type power supply during training. In some examples, this selective enablement/disablement may be based on whether the GTAW training system is in a live-arc mode or simulation mode

Methods and systems for using near field communication (NFC) protocol and logic to calibrate welding operations and systems are described. Further, methods and systems for using NFC logic and tags are described for networking, calibrating and linking components that comprise welding systems.

A welding system includes a multi-process power supply, a TIG torch, and a TIG power pin for connecting the TIG torch to the multi-process power supply. The multi-process power supply has a power output connection for a MIG torch and a controller. The Controller is configured to command shielding gas and welding current to be provided to the power output connection, and the power output connection is configured to provide the shielding gas and the welding current to a MIG torch when the MIG torch is connected to the power output connection. The TIG power pin connects the TIG torch to the power output connection such that the power output connection is configured to provide the shielding gas and the welding current to the TIG torch. The controller is configured such that at least one of the shielding gas and the welding current is not provided to the TIG torch through the power output connection until a user engages a control member.

Disclosed are apparatus and systems to determine voltage measurements in welding-type applications to facilitate control of welding-type processes. Disclosed systems include a remote operations interface configured to facilitate voltage measurements in welding-type applications and facilitate communication between a welding-type power supply and a wire feeder.

Disclosed are an adaptive control method and equipment of arc swing in narrow gap welding. The control equipment is composed of an infrared camera system, a computer image processing system, an arc swing parameter control system, a bent-conducting-rod-type swing arc torch and the like. The infrared camera system acquires, in an external triggering manner, an infrared image of welding area when an arc is deviated towards the left or the right side wall groove, extracts information about the width of the groove in real time after image processing by a computer, and calculates an arc swing angle target value. The arc swing parameter control system controls a motor drive mechanism to rotate a bent conducting rod, and drives the welding arc to conduct circular arc swing according to the swing angle target value, thereby realizing the adaptive control for the arc swing angle according to changes of the groove width.

Engine-driven welding-type power supplies with portable welding units are disclosed. An example engine driven welder includes an engine, a generator configured to convert mechanical power from the engine to electric power, a chassis, the engine and the generator being mounted to the chassis, and a welding power supply configured to receive the electric power from the generator and convert the electric power to welding-type power, wherein the chassis is configured to physically hold the welding power supply, the welding power supply is physically separable from the chassis, and the welding power supply is connected to be able to receive the electric power when the welding power supply is separated from the chassis and when the welding power supply is connected to the chassis.

Embodiments of systems and methods for supporting weld quality across a manufacturing environment are disclosed. One embodiment includes a manufacturing cell supporting welding of a sequence of welds to manufacture a workpiece. The manufacturing cell includes robotic welding equipment to make robotic welds as at least a portion of manufacturing a workpiece. The manufacturing cell also includes non-robotic welding equipment configured to allow a human operator to make non-robotic welds as at least a portion of manufacturing the workpiece. The manufacturing cell further includes a weld sequence controller configured to control timing associated with making the robotic welds and the non-robotic welds as a sequence of welds to manufacture the workpiece.

This disclosure describes systems, methods, and devices related to robotic point capture and motion control. A robotic device may synchronize one or more first axes of the robotic device with one or more second axes of a handheld device. The device may determine a welding path using the handheld device. The device may perform a weld by the traversing of an end effector of the robotic across the welding path, wherein the end effector comprises a welding tip.

Systems and methods for distributed weld monitoring using jobs and job sessions are described. In some examples, a distributed monitoring system comprises a central monitoring station in communication with a user device and a local monitoring station. A user may use the user device to enter weld monitoring data that is subsequently received by the central monitoring station and stored in a central data repository. The central data repository may associate the weld monitoring data with welding data received from a welding device, as well as with a job session that is, in turn, associated with a job.

Systems and methods for weld monitoring systems with unknown downtime disabling are described. In some examples, a local monitoring station may perform activity tracking as part of a larger weld monitoring system. A welding device may send welding data to the local monitoring system, which may be used to determine a current activity. A user may also manually input an activity to use as the current activity. If the local monitoring station is unable to determine a current activity from the welding data or user input, then the local monitoring station determines that an unknown downtime has occurred. If the local monitoring station cannot determine a reason for the unknown downtime, the welding device may be disabled until the user provides a reason for the unknown downtime.
