There are styles of music that rely on the amplification of a harmonica by utilizing a microphone and an amplifier. Aural notification is provided by positioning a device at least partially within the auditory canal, processing a digitized notification signal at the device, and aurally presenting a predefined notification message from the device responsive to the processed digitized notification signal. It has been observed that initiating the arc using a substantially higher average arc current and thereafter switching the power supply to a CV mode for the remainder of the Gas-Metal Arc welding operation decreases the arc initiation period and the instability produced during this arc start period. The switch instructions necessary to implement this scheme are generated automatically.
