Battery contacts in automatic welding helmet

Since the development of the automatic welding helmet, Optrel has been developing innovative systems for eye and respiratory protection for private and professional welders. The helmets are sold worldwide. At the core of each automatic welding helmet is the cartridge which combines both the technology and the know-how. Part of this cartridge is a printed circuit board upon which the controller is integrated that regulates the liquid crystal display depending on the brightness.

There are two CR2032-type button batteries on the printed circuit board, each of which is secured in place by a battery holder with a positive pole and a battery contact with a negative pole. Vogt AG has produced complex battery contacts for the company based in Eastern Switzerland. The stamping-bending tool was designed using modern 3D software, machined on the CNC milling centre and wire-eroded onto the Swiss quality machines. Both parts were stamped in an internal stamping tool and were then hardened and finished. To ensure the high quality requirements with the series, the parts are examined right down to the last detail during the quality check. Consistently high quality is ensured at Vogt through regularly trained personnel.
