Lorch MX350 Portable Mig/Stick/Tig Power Source.

M as in MIG-MAG-mobile and multi-process. 
X as in eXtra strong thanks to MICOR inverter technology.


MIG-MAG optimised for mixed gas and CO2 
plus synergic and multi-process applications: Lift TIG, electrode, CEL

Easy operation is one of the particular strengths of the MX 350. It lets you select the welding process of your choosing with a turn of your wrist. You can switch between MIG-MAG with mixed gas or CO2, Lift TIG and electrode welding with the press of a button.

The unit also allows you to enable MIG-MAG synergic mode directly and adjust the settings with ease: Simply select the characteristic curves, and the system will automatically adjust the wire feed to each voltage setting.

Finally, inverter technology makes it possible to achieve specific end crater filling – to give a clean finish to your weld seam.

Mobility made easy

Daily grind at the construction site: Hard installation work, inspections looming, all trades are rushing to finish the job. Costly rework or delays are out of the question. This is the type of situation where you need a mobile welding system on which you can fully rely.

Not a problem if you have the MX 350. Naturally, having such a versatile and well-performing unit handy is a big plus. Granted, it will not fit in your trouser pocket, but we certainly designed it such that it will be easy for you to move
around with it.

The MX 350 sets itself apart by the lowest weight and most compact dimensions you will find in this performance class. When you carry the unit, you will find that the separate wire feeder case provides comfortable weight distribution by offsetting the weight of the unit, thereby preventing excess stress on one side. What is more, it allows you to leave the power source behind and take only the case with you, for instance, on the scaffolding. Your power source can certainly take a beating during your everyday work thanks to its exceptional protection against falls from a height of up to 60 cm and, in particular, its all-around splash-proof housing (protection class IP34).

All in all, nothing will stand in your way when setting out to do professional work on the go – regard less of the terrain you are dealing with.

MIG-MAG feeder - simple, convenient, and robust.

When performing installations in the field, you will need a feeder that is, above all: convenient and robust. All components that carry an important control function are housed safely inside the power source. Everything inside the feeder is designed such that you can handle any task ranging from sheet metal welding to medium and heavy steel work. And, to ensure that you stay “wired” while completing your welding job, your feeder is equipped for the use of K 300 wire reels.

The operating panel is straightforward and clearly arranged and is ideal both for manual operation and the synergic mode of the MX 350. When using the latter, you can set such basic parameters as the characteristic curve, the operating mode, crater fi lling, etc. directly at the power source. You can adjust the voltage setting either at the system or the feeder. To fine-tune the wire feed, you always use the operating panel on the front of the feeder.
