Max 191 PFC

Brand Name: STEL

Model: Max 191 PFC

Origin: Italy



• Maximum Efficency

The Inverter Welding Power Source MAX 191 PFC developed by STEL with INVERTER technology, concentrates high welding performance in a compact structure. Ideal for 3,25Ø electrode and other type like 4Ø electrode.

Power Factor Correction regulating wave form distortion from Input Voltage and Current supply, providing a constant Voltage to the Inverter.

In respect of stringent EN Standards for Harmonic Distortion (EN 61000-3-12) and the energy efficiency ERP. Energy savings of 30% compared to a normal Inverter and up to 50% to an SCR.


• Control of PFC regulation through DSP technology.

Max 191 PFC is able to weld 4mm under 16 AMP. fuse.
