Resistance Welding Control Unit – TECNA TE750

TECNA TE750 – Mid-Frequency Welding Controller

TECNA TE750 is a mid-frequency weld controller, it may work with constant current and fix.

Using the TECNA TE750 controller, it’s possible to store up to 150 different welding programs. Each program can contain many programmable parameters that describe the work cycle. Furthermore, to the plain 4-stage welding cycle, the weld control unit allows the running of welding processes with pre-welding current, post-welding current, slope and pulses.
