ABSTRACT:
A welding flash protection apparatus for use with a welding machine with gas shielding is disclosed, the apparatus providing for delay of the welding flash thereby preventing the typically inherent fraction of a second delay between flash and lens darkening, hence protecting the eyes. The apparatus provides a complete helmet or apparatus components for fitment to an existing helmet. The apparatus provides a unique transmitter antenna mount for the shielding gas tank.
