    • The present invention relates to an improved resistance weld-based gun assembly for use in an electric welding system without a need for plant-provided air and water-cooling circulation systems. In one aspect of the invention, a resistance-based force controller measures the resistance of a secondary circuit of the weld gun, the combined resistance of the secondary circuit in parallel with the circuit formed by the workpieces and opposing electrodes when sandwiched between the electrodes, and calculates the resistance of the workpieces. The measured resistance is compared to a predetermined resistance and the sandwiching force of the electrodes incrementally adjusted until the resistance of the workpieces is acceptable. The invention also relates to a closed loop coolant system having a coolant line, a coolant contained within the coolant line, a heat exchanger, and a mechanical coolant pump. One possible pump comprises an elastic bladder dependent upon the state change of the coolant. A second possible pump comprises a reciprocating extractor mechanically connected to the weld gun actuator. In yet another aspect of the invention, the welding system relies solely on electrode arm material for heat dissipation, the heat being conducted through the electrode arm material to an outer surface of the arm where the heat is dissipated through natural convection. To promote natural convection, a plurality of ribs with channels defined therebetween or openings extending through the arm itself increase the surface area and the rate of convection.
    • 本发明涉及一种用于电焊系统中的改进的基于电阻焊接的枪组件,而不需要设备提供的空气和水冷循环系统。 在本发明的一个方面,基于电阻的力控制器测量焊枪的次级回路的电阻,当夹在电极之间时,次级电路与由工件和相对电极形成的电路并联的组合电阻, 并计算出工件的电阻。 将测量的电阻与预定电阻进行比较,并且电极的夹持力逐渐调节直到工件的电阻是可接受的。 本发明还涉及一种具有冷却剂管线,冷却剂管线内的冷却剂,热交换器和机械冷却剂泵的闭环冷却剂系统。 一个可能的泵包括取决于冷却剂的状态变化的弹性囊。 第二可能的泵包括机械地连接到焊枪致动器的往复式抽出器。 在本发明的另一方面,焊接系统仅依靠用于散热的电极臂材料,热量通过电极臂材料传导到臂的外表面,其中热量通过自然对流消散。 为了促进自然对流,具有限定在其间的通道的多个肋或延伸穿过臂本身的开口增加了表面积和对流速率。
