SM HF-250 inverter pedestal spot welder
SM series pedal operated rocker arm pedestal inverter spot welder.
Sturdy structure. Water cooled and vacuum impregnated transformer. Adjustable arm position both in length and height (gauge). Adjustable electrode pressure. The unit also includes the “MICRO8” weld synchronous control board with a diode microprocessor controlled in 5 steps, equipped with double programme and pulses. 1000Hz control frequency inverter generator for medium frequency transformers. The compact device allows to control the primary current of the power transformer keeping its value constant regardless of the variations in the mains voltage and any thermal and aging drifts of the different components of the system. The working frequency of 1KHz allows to reduce the dimensions of the transformer and to improve the form factor of the output current by reducing the ripple of the current and allowing the creation of more controlled welding points both in terms of time and maximum current. The inverter control board interfaces with the remote unit such as MICRO8 or J-TEK provides the welding parameters and sends error codes to manage diagnostics in the event of anomalies.
