1510c 1530a


  • Very good precision on the current control thanks to the double feedback both on the primary and the secondary circuit.
  • Reduction of operational and maintenance costs.
  • Excellent flexibility and adaptability to the materials to be welded.
  • Adjustment of the welding current per milliseconds. This enables a very precise adjustment of the welding process.
  • As compared to an AC welder, inverter medium frequency technology produces a much more efficient heat output and this allows to obtain the same welding result in a shorter time and to reduce the heat dispersion around the nugget (HAZ heat affected zone) without affecting the features of the material.
  • Very compact welding transformers (almost 50% smaller as compared to AC ones).



  • Frequency of the inverter between 1000 Hz and 4000 Hz.
  • Storage of up to 300 welding programs.
  • Possibility of managing as many as 4 different welding transformers or one transformer and 4 different types of electrodes.
  • Slope up, Slope down, pulses, pre-weld, post-weld functions and adjustment of the welding times with units of 1 ms.
  • 6 WORKING MODEs: conventional, constant current, constant power, constant voltage, FIX, constant energy, DYNAMIC mode.
  • Limit indicators for: Current, voltage at the electrodes, energy, power, inverter use percentage, initial and final resistance of the material to be welded; thickness and indentation limit of the material (optional).
  • Stepper function to compensate the wear and tear of the electrodes with programmable curves and possibility of intervening independently on the time and the welding current through differentiated stepper laws. Possibility of using 4 different stepper options associated with 4 different spot counters associated with each weld program.
  • Output for proportional solenoid valve.
  • Possibility of upgrading control unit Firmware via appropriate software.
  • Electrode tip dressing for up to max of 4 different spot counters (optional).
  • Programming and reading the welding data within the inverter by web server.

1510c 1530a system



A software for programming and reading the welding data is within the inverter 1510A.
By connecting with a PC via the Ethernet port on the inverter (X2), one can log in and access the programming and reading of the welding data by simply opening
one's web browser (Explorer®, Chrome® etc., etc.). Possibility to do BACKUP/restore of unit.
Fieldbus is meant to be a single master and multi slave communication network, which allows reducing the wiring required between the nodes making up the network in that it requires the laying of only one cable. In general, it is used to connect a master, such as a PLC, to remote Inputs/Outputs.

The TE71 is a microprocessor-based graphics programmer for resistance welding control units. It is designed to remotely display and configure the installation and working parameters of a series of welding control units by means of CAN communication. It can be interfaced directly to the specific control unit or added as a node to a network of control units.
Its graphical interface allows the user to navigate within free-access menus or within menus having password-controlled accesses. It also offers the data backup option using a USB support.
TecnaNet Ethernet is a communication programme, based on TCP/IP (Transfer Control Protocol / Internet Protocol), developed by TECNA for remotely programming the control units linked inside a local network.
This programme not only manages the entire programming of all the control units linked together in the network but may also be used to create a detailed documentation of its output, allowing the user to file all data for each welding spot that the networking control units have carried out.
Furthermore, this programme offers the possibility of creating backups of all the programmes stored inside the control units, which markedly speeds up replacements when required.
