TE195

 

 

The TE 195 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 efficiency of the safety devices which can be installed on the machine. It is possible to program and to store up to 15 different welding programs. All the programs can be recalled directly from the keyboard and program number 2 can be recalled from an external device. The control unit can be programmed for working under two different operating modes: standard one and and constant current. Each program can assume all the configurations included between the simplest 4 times cycle, up to the most complex one, which can include the slopes, the pulses and the post-heating. Other available functions are the welding current stepper function and, under standard operating mode, the compensation of the variation of the mains voltage and the compensation of the minimum current.
