MX 350

Resilient.

The Lorch MX 350 is optimally equipped for mobile outdoor use with its robust and weatherproof housing with IP34 and a drop resistance of up to 60 cm height.

Extra performance with the MicorBoost.

Significantly higher voltage reserves can be activated when external interferences drop the current, leading to perfect MMA welding.

Synergy mode.

With optional MIG-MAG synergy mode for excellent MIG-MAG welding properties with mixed gas and CO₂ alike.

Multi-process and full flexibility thanks to MF-07 wire feeder.

The MX 350 is an excellent tool for mobile use as well when combined with the separate wire feeder MF-07. The MF-07 can cope with all kinds of sheet metal and medium to heavy steel work.

The case is designed for use with K 300 wire rolls to keep you up to speed when welding. It is also TIG-, MMA-, and CEL-capable, permitting adjustment to various tasks at need.

Country-specific product variants.
