Origo™Arc4001i, A22/A24

Optimum Welding Solutions

Robust and powerful

An Origo™Arc 4001i with either the A22 or A24 control panel, is your ideal partner for efficient MMA welding production indoor or outdoor, installation on site and for a wide range of repair & maintenance applications.

The power source is a compact and sturdy piece of equipment with a chassis made of galvanized steel which is designed to withstand the roughest of treatment.

The power source is based on inverter IGBT technology that ensures reliable equipment with outstanding welding characteristics.

The communic ations and control CAN-bus system means less cables, which in turn increases operational reliability.

MMA applications

Origo™Arc 4001i can weld most metals from alloyed and non alloyed steel to stainless steel and cast iron.


The fundamental parts are the 400 A power module. The link between man and machine is the communicator. You can choose between two control panels (MMC) depending upon your requirements and demands. Both of them are clear, easy to understand and operate.

Origo™A22 is a one knob panel for setting and adjustment of welding current in MMA and TIG (LiveTIG™) and includes a digital ammeter.

Origo™A24 is a more sophisticated panel for MMA, TIG (LiveTIG™) and MIG/MAG (CV mode) inclusive a digital A/V-meter.
