Portable DC Inverters

The PRESTO PFC range is fitted with the new SAF-FRO inverter technology.

The PFC controller is the technical solution to achieve conformance to the limitation of the harmonic current for equipment connected to public low voltage network which is now mandatory in Europe (EN 61000 - 3 -12 standard).

PFC results in lower effective current consumption at the same output welding power, also maximising electronic component lifetime.

PRESTO 140 PFC / 160 PFC / 180 PFC

Features:

• Improved generator compatibility with PFC controller addition.

• Hot start and anti-stick functions.

• Reduced noise. Intelligent cooling fan.

• Ergonomic handles for carrying and cable rolling.

• Usable with long primary extension cable

(70 m in 2.5 mm 2 section).

• Lightweight - 6.6 kg.
