Welding device for fixed contact assembly of molded case circuit breaker

The utility model relates to a welding device for a fixed contact assembly of a molded case circuit breaker, which comprises a support supporting seat, a ceramic compression bar and two electrodes, the support supporting seat is used for supporting a support, the ceramic compression bar compresses an arc striking angle and a contact on the support, and the two electrodes respectively abut against two sides of the support opposite to the arc striking angle and the contact. By the adoption of the scheme, the welding device for the fixed contact assembly of the molded case circuit breaker can complete high-quality welding procedures of three parts made of different materials such as a support, a contact and an arc striking angle at a time, welding flux overflows evenly on the appearance of a contact assembly product, the welding brazed rate is larger than or equal to 85%, and the performance indexes of the shearing force, the metal phase and the like are good. 本实用新型涉及一种塑壳断路器静触头组件的焊接装置，包括支架支撑座、陶瓷压杆和两个电极，支架支撑座用于支撑
