ABSTRACT:
A welding system with an automatically operated helmet closes the helmet's hood, and thus its face mask, before turning on a welding electrode. The system includes an actuator with a piston that mount to the helmet's headband and hood, respectively. Only when the system detects that the mask is closed will power to the electrode be actuated. This system is controlled by a safety circuit, which the welder simply plugs the helmet into for automatic control. If the welder does not plug into the safety circuit, the system operates similar to a conventional welding system.
