Abstract: 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.
