Methods and systems for transmitting a torch angle and/or a torch-to-workpiece distance error to a welding operator when these parameters are outside of a preset optimal range via real time visual and/or audio cues are provided. One embodiment of the present disclosure relates to weld characteristic communication via intuitive arrays of visual indicators located on the periphery of a lens, which indicate to the welding operator the direction and severity of the torch angle error. In one embodiment, audio cues, such as pulsed or continuous tones may be used to communicate torch-to-workpiece distance to the welding operator. In certain embodiments, vertical visual indicator arrays may be used to indicate additional weld or auxiliary information, such as battery charge state, torch speed and so forth, to the welding operator. All the components of the communication system may be located in or on the welding helmet or the components may be split between the helmet and a belt pack.
