The TE751 is a medium frequency welding controller, it may work with constant current and fix operating modes.


It is possible to store up to 150 different welding programs. Each program comprises several programmable parameters that describe the work cycle. In addition to the plain 4-stage welding cycle, the control unit allows the running of welding processes with pre-welding current, post-welding current, slope and pulses. 



  • Easy programming through 9 keys and backlit graphic LCD display.
  • Inverter command with medium frequency IGBT, with possibility of choosing the operating frequency of the inverter between 1000 Hz and 4000 Hz.
  • Storage of 150 welding programs, up to 15 which may be called from the outside.
  • Up to 16 programmable parameters for each program.
