    • A clip on welder includes two pairs of opposed grippers defined by pivotally attached upper and lower frames for latching the welder to heat weldable material, such as a length of tubing, upon actuation of a start button by an operator; thereafter, the welder operates unattended. At least a jaw of a pair of jaws disposed intermediate the two pairs of grippers heats the material compressed and lodged therebetween to form a weld in or across the material. A source of gas, such as air, under pressure selectively connected to a bellows provides the power to pivot the upper and lower frames into gripping engagement with the material. A source of electrical signals provides the power to heat the material intermediate the pair of jaws. One or more thermocouples senses the heat of the jaws and generates signals used to control the application of power and to control cooling. After completion of the weld, cooling air is directed to the jaws until the thermocouple(s) signal(s) indicates a sufficiently low temperature. Release of the welder from the material is in response to actuation of a stop button by the operator.
    • 焊机上的夹子包括两对相对的夹持器,其由枢轴连接的上框架和下框架限定,用于在操作者致动起动按钮时闭锁焊机以加热可焊接材料,例如一段管道; 此后,焊工无人值守。 至少设置在两对夹具之间的一对钳口的钳口加热被压缩和滞留在其间的材料,以在材料中或整个材料上形成焊缝。 诸如空气的气体源在选择性地连接到波纹管的压力下提供了使上框架和下框架枢转成与材料夹紧接合的动力。 电信号源提供加热该对夹爪之间的材料的功率。 一个或多个热电偶感测颚的热量,并产生用于控制功率的应用和控制冷却的信号。 焊接完成后,冷却空气被引导到夹爪,直到热电偶信号表示足够低的温度。 焊接机从材料的释放是由于操作者致动停止按钮而产生的。
