The M-Series.The MIG-MAG classic raised to perfection.

The workshop favourite for MIG-MAG-welding for more than three decades.

A Lorch M-series welding system serves as a gateway to professional MIG-MAG-welding due to its high-tech qualities and sophisticated detailed solutions. The M series is the absolute classic and perfect all-rounder for the trade – and has been for over 30 years. 

At the same time, the M-series has always kept pace with technical development: Welding with an M-system today leaves very little work to the welder thanks to a robust, resilient, and perfectly reliable MIG-MAG welding unit

The M-series: Tried and tested welding systems full of high-tech.

Perfect welding properties for best results.

Since the M-series was introduced three decades ago, it has always provided the quality and robustness of Lorch MIG-MAG welding units. This has never changed, even as cutting-edge technology such as microprocessor control, feed motor technology, and an automatic setting system were added. 

Contemporary M-welding systems offer a full package of practical features, from the processor-controlled MIG-MAG logic to the large, stable wheels, the overload-proof rectifier, and a powerful cooling system. The core is one of the best 50 Hz main transformers with ideally matched welding choke. Of course, all of this is made in Germany


Efficient automatic adjustments.

Always find the perfect working point with the help of the automatic adjustment of the wire feed speed to the selected voltage level.

Optimal wire feed.

The wire feed with tension-free wire threading can be controlled at the touch of a button in the ergonomic wire feed compartment. 

Double gas cylinder safety device.

Safely move your power source including gas cylinder (up to a maximum of 20 litres). 

High performance.

Switchable devices can also be switched to 230 V when the heavy-current power plug is connected.

The operating concept of the M series



  • “3 steps and weld” operating concept
  • Current settings in 6-12 steps
  • Automatic settings (synergy function)

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 the best advice: close, personal and honest.
