TE470 Welding Control Unit

The TE470 is a microprocessor welding control unit designed specifically for suspended resistance welding guns. Its primary function is to control various components of the welder, with a particular focus on regulating the thyristors that adjust the welding current. This control unit offers specialized features for working with suspended welding guns, including double stroke control and the ability to monitor the effectiveness of safety devices installed on the machine’s handle.

It’s important to note that the handle is not included as a standard component of the welding control unit. However, the machine allows for the installation of different handles, allowing users to customize the settings based on specific performance requirements.

With a generous storage capacity, the TE470 can store up to 63 different welding programs. Users can directly recall two programs using an external selector typically installed on the handle, even when multiple handles are active. Each program consists of 19 adjustable parameters that describe the working cycle in detail.

In addition to the standard 4-times cycle, the control unit enables the execution of more advanced welding processes. This includes the ability to incorporate pre-weld current, post-weld current, slope, and pulses. The TE470 is capable of operating in constant current mode, providing a display of the welding current and monitoring it against the set limit for enhanced control and accuracy.


  • Simplified programming by means of 5 push-buttons and LCD alphanumeric display.
  • Controlled-diodes synchronous drive with phase shift control for welding current adjustment.
  • 63 welding programs to be stored up; 2 programs can be recalled from the handle.
  • Possibility of connecting 2 handles.
  • 19 programmable parameters or more for each program.
  • Slope and pulse functions; pre-weld and post-weld functions.
  • Welding times adjustment in half-periods.
  • Display of both welding current in kA, and connected conduction angle.
  • Operating modes: conventional and constant current.
  • Either welding current or conductor angle limits.
  • Automatic double stroke function (to be employed only when the welder has been designed for this function).
  • Three working modes along the machines stroke: SHORT, LONG, AUTO.
  • Stepper function to balance the electrodes wear-out with adjustable curve.
  • Welds counter.
  • Single and automatic cycle. WELD/NO WELD function.
  • Delay of first phase shift adjustment to get the bet balance of the machine absorption from the mains.
  • Control of 2 solenoid valves 24 Vdc 7,2 W Max with protected output against short circuit: electrodes closing valves and double stroke valve.
  • Self-adjustment to the mains frequency 50/60 Hz.
  • Data communication with RS485.
  • Password for locking the programming.
  • Selectable languages: Italian, English, Spanish, German, French, Hungarian, Portuguese and Swedish.
