PECO Welding Systems GmbH
In 1908, on the initiative of the engineers Pfretzschner & Bocks, PECO Widerstandsschweißtechnik was founded in Pasing (Munich, Germany) and immediately established itself as a leading industry in the field of resistance welding, introducing regular developments and innovations that have contributed and still contribute to making history, from the use of Hygrotron (1950) and then Semiconductors (1963) and Power Transistors for secondary current regulation (1980), to the introduction of the Microprocessor (1985) and today's Integration with the PC with remote maintenance via IP or SIM and the widespread use of the motorized head. Since 1950, PECO has dedicated itself more and more exclusively to microjoints with resistance micro-welding, which is used in the electromechanical, automotive and white components, electronic, space, medical, fine mechanics, etc. sectors.
The ARQ3 is a time relay. In the starting position, there is no connection between the electrodes. When the tube is rotated, mercury flows through the hole in the direction of the right electrode and establishes an electrical connection (at least 16 A). After a certain amount of mercury has been transferred, the current is interrupted. The inclination determines the time during which the mercury flows.
