A welding system and welding helmet is provided, where the welding helmet is capable of providing an image representative of information from an associated welding operation where the image appears as a head-up display (HUD) in the welding helmet. The helmet displays the information at a focal point which coincides with a working distance of a welding operation so that a user need not change his/her focus during a welding operation. The helmet also comprises a microphone to allow for audio instruction to be provided to a welding power supply to change settings.
