THE MX-Series.Hard at work on construction sites and in maintenance.

M stands for multi-process. X stands for extra-strong.

Have you always wanted a mobile MIG-MAG solution that outperforms all the others? After all, every site and every welding task comes with its own, very special and unique challenge. This device lets you face any task in a versatile and efficient manner. 

Combined with a separate wire feeder, the MX 350 is the perfect MIG-MAG welding unit for mobile use. It will confidently weld wire diameters up to 1.2 mm. 

Every step needs to be perfect in welding units.

Overview of the advantages of the MX series.

Everyday work at the construction site: Hard assembly work, pending acceptance tests, all trades are putting on one last burst of speed. Expensive rework or delays are unthinkable. This situation requires mobile welding systems that can be relied upon perfectly even in rough applications. 

This is where the MX 350 shines. Of course, it is sheer pleasure to have a machine at hand that is so very versatile and can weld so well. 

The MX 350 stands out with its very low weight and compact size for this performance class. The separate wire feeder ensures comfortable weight distribution when carried and reduces unilateral stress. 



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 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. 


Operation made easier.

The intuitive operating concept renders long setting times obsolete. Simply switch on the device, select the welding process, and set the welding current. For best results, immediately. The automatic adjustment function optimises parameters adaptively in the background. 



  • “3 steps and weld” operating concept
  • Simple one-button operation
  • Amperometric digital display
  • Electrode preselection (basic, rutile, and CEL) for optimal welding parameters
  • Hot start in submenu

3 steps and welding:

Best operation. Best welding result.

Lorch systems are so easy to operate because we integrated many of the things you have had to adjust since as assistance systems during development. A maximum of 3 steps and you weld perfection. The rest runs in the background. A very good system serves you, not you it. Operate - without you having to deal with it.

Always well-advised with close, personal, and honest support.
