Power Inverter Inside

Higher efficiency and better welding quality than conventional power sources. Overall weight reduction for easier transportation and movement. Weco Inverter supplies a better quality welding arc, with no spattering, repeatable in time and unaffected by main voltage fluctuation.
Reworking time and money saving. Real lower overall electric consumption.

W-ECO Technology Inside

W.ECO technology according to EN-60974-10, reduces harmonic current

Weco Power Factor Corrector

W.ECO PFC reduces harmonic current emissions and 20% input current, increasing the power inverter efficiency.

Total Protection

A built-in Total Protection Device saves the inverter components from overvoltage and makes the unit suitable for use with unstable power supply and motor-generators.

Volt Reduction Device

Function VRD (Volt Reduction Device) reduces automatically the voltage of the welding machine during the Standby mode in order to allow the processing in those building site where low voltages are demanded for safety reasons (Dockyards, petrol platforms and so on).

Hybrid Arc Control

WECO unique HAC (Hybrid Arc Control) supplies a soft and very stable MIG/MAG welding arc with excellent weld bead quality and minimal spattering in any working conditions.

Weco Digital Control

The Inverter is by the latest generation DSP device (Digital Signal Processor) digitally controlled, this permits a steady precise and quick adjustment of the welding arc.


The Power Source can be connected to most common three-phase supply- net, it means that the inverter adjusts automatically its parameters to the available supplying voltage in order to grant in any case a perfect welding.

Weco Data Manager

Weco has developed the DATA MANAGER tool for complete welding’s control and monitoring. The WECO DATA MANAGER software allows you to control simultaneously multiple Weco Power Sources connected to a dedicated LAN (ETHERNET). Connected Power Sources auto-discovery system allows an easy and fast connection, ready for detecting, monitoring and setting welding parameters.
