STEL MAX 191 PFC Welder + ACCESSORY KIT + Bag

The STEL MAX® 191 PFC, developed with INVERTER technology, packs high welding performance into a rugged structure. Ideal for welding 3.25Ø and 4.0Ø electrodes. 

PFC (Power Factor Correction) technology allows: 

– Correct Voltage Waveform Distortion 

– Correct Current Waveform Distortion 

– Putting the Voltage in Phase with the Current 

– Always supply the inverter with constant voltage. 

– the infinite flexibility of PFC technology allows the use of power cables up to 500m long
– 30% energy savings compared to a normal inverter

It allows compliance with the most stringent regulations on Harmonic Distortion (EN 61000-3-12) and Energy Efficiency ERP.
