Abstract
The user of electric arc welding equipment is provided with audible feedback signals which provide useful information relating to the output current and voltage of the welder. An audio tone is generated and is frequency modulated by a signal which corresponds to welder output voltage. The tone is amplitude modulated by a signal corresponding to output current thus providing the user with a synthesized feedback signal having a voltage-proportional pitch and current-proportional volume. Additional modulation means are disclosed for introducing a current-proportional warble component to said tone.
