Max 403/403S

Brand Name: STEL

Model: Max 403/403S

Origin: Italy

Description:

• The various Multi-Process combinations of this robust “Globetrotter” with its advanced Inverter Technology, increases the level of operator safety to a wide range of welding applications. With easy simple external switching and connections, “optional Add-On Process” fearture are: MIG/MAG; PULSE MIG/MAG; FLUX CORE;DC TIG with HF ignition; CC/CV.

• The MAX 403 Multi-Process/Multi-Function Inverter is available in the following versions: MAX 403 and MAX 403S

• Owing to the advanced Autosensing Technology, the MAX 403s is ready to operate from any external input power supply. This highly sophisticated device automatically links the Primary Voltage supplied from 200V up to 600V, without manually linking Primary Voltage terminals. No switching or internal/external link-up is required by the operator.

• The PFC technology of the MAX 403s version, requires less electrical input to the Inverter power source by utilizing the total current available from the input supply. This results in more than 30% savings from avoiding any energy loss. The unique PFC flexibility further increases the many advantages to the operator such as, providing opportunity to use welding cables up to 500m long,..generator friendly,..VRD.
