• Nederman's Weldomatic is designed to avoid the blind petiod after positioning a welding electrode when the mask is raised prior to the arc being struck.
It looks like the traditional welding mask but has a lightly tinted glass that automatically darkens as the arc is struck.
There are six pre-set darkness settings on the system: three for gas welding, three for arc welding. Reaction time for the lens to darken is said to be less than 0.001 seconds.
There is also a TIC setting on the shield where the light emitted by the weld is measured by the solar cell arrangement and the darkness of the lens is varied accordingly.
The main power for the system is provided by solar cells in the front of the mask, but there is a small back-up battery.
The Weldomatic can be used in conjunction with fresh air filter systems and costs £215 (exVAT).
