MICORMIG 350

Perfect welding results.

The innovative and patented Micorboost technology maximises power and the voltage reserve in the arc, optimising welding properties for all sheet metal as well as medium and heavy steel work with mixed gas or under CO2 alike. Outstanding welding results on steel, stainless steel, and aluminium are the result.

Compliant and combinable.

Easily weld EN1090 compliantly thanks to the WPS booklet. Save some time- and cost-intensive individual tests of your welding results. The booklet contains independently certified welding instructions for all the relevant standard welding procedures. The MicorMIG 350 also keeps your parameter sets conveniently available via an NFC job card.

Future-proof & flexible.

Expand your system at any time with the precise functions you need: The NFC function makes the MicorMIG 350 fully upgradeable, allowing you to subsequently install additional welding processes, welding programmes, and functions to facilitate work with NFC cards at any time, offline and without needing any external support.

Quality assurance with the authorisation concept.

NFC technology allows setting up of a personalised authorisation system for welding system operation. The MicorMIG 350 allows use of NFC authorisation to ensure that only specific welders are allowed to adjust the corresponding parameters. A timed lock for the end of the working day additionally prevents unauthorised work on the device.

Outstanding price-performance ratio.

The MicorMIG 350 offers an easy switch to a fully adjustable welding system. Profit from the optimal welding properties of the MicorMIG 350 at an excellent price-performance ratio. It simply is the better alternative to the conventional transformer system.

Energy efficiency by technology.

The MicorMIG combines robust performance with efficient inverter technology and a stand-by function. This reduces costs while achieving perfect welding results.
