Max 161 PFC Autosensing

Brand Name: STEL

Model: Max 161 PFC A-S

Origin: Italy


Maximum Reliability. 

This generation of Inverter is able to optimize he input power with the innovative PFC (Power factor Control) feature. The advance PFC dynamics allows the complete exploitation of the available input amps resulting in the delivery of the required welding current without power leakage.

The Max 161-PFC Auto-sensing is able to operate from any single phase input voltage in the world. This sophisticate device automatically links the primary Voltage supplied from 90V up to 280V without manually linking primary voltage terminals. No switching or internal link-up required by the operator.

The INVERTER reliability is drastically improved compensating for any Voltage spike that occurs within the input range giving occasion for use with smaller generators saving weight and dimensions.

The operator will have the opportunity to weld a 2.5Ø electrode with extension of 500m long.
