WELDING CONTROL UNIT TE300
TE300 is a microprocessor welding control unit for suspended resistance welding guns. This control unit includes specific functions to be used when working with suspended welding guns, such as the double stroke control, and a function checking the efficacy of the safety devices which can be eventually installed on the handle of the machine. It is possible to program two different welding programs which can be recalled by an external device. Each program is formed by eleven programmable parameters which describe the working cycle. Besides the simple four times cycle, the control unit enables to carry out welding processes with pre-weld current, slope and pulses. Another available function of this control unit is the compensation of the minimum current. TE300 image
