The S-RoboMIG XT seriesFor maximal performance on the robot.

High-end automation: Control, quality, and perfection

As the state-of-the-art solution in robotic arc welding, the S-RoboMIG XT series is perfect for interfacing with welding robots from any manufacturer. The full, perfectly balanced package offer includes the torch, wire feed, power source, and cooling unit. Attachments for robot type to match are available as well. Thanks to the adjusted quality of the synergic lines and processes for all relevant welding tasks ex works renders product customisation unnecessary.

The high-end control technology of the Lorch S-RoboMIG XT series provides a signal from a plethora of information to be evaluated by the robot controller for standard and pulsed arc processes alike. This weld seam detection and seam tracking functions enable the robot to constantly and automatically adapt the torch guidance to actual workpiece conditions. The signal provided can be used for vertical and horizontal adjustment of the torch guidance.

Overview of the advantages of the S-RoboMIG series.

Lorch S-RoboMIG welding systems offer the matching solution with perfect welding results for all materials and weld seam requirements.


Perfectly integrated.

Simple and quick integration into different automation systems for all common robot manufacturers thanks to common digital bus protocols and two analogue interfaces to choose from.

Outstanding welding properties.

Cutting-edge processor technology ensures optimum interaction of all parameters and components involved in the welding process while maximising arc performance.

Peak values in arc control are achieved and optimal welding results can be reproducibly achieved for all materials.

Sophisticated design

The S-RoboMIG XT has been built to live up to all requirements for many years of use. A gas cylinder holder, crane rings, torch holders, and a robust build complete this portfolio.

Certified quality.

The EN 1090 WPS folder avoids time- and cost-intensive individual tests of the welding results. The folder contains independently certified welding instructions for all the relevant standard welding procedures.

Lorch Speed processes.

The default Lorch SpeedPulse XT, TwinPuls XT, SpeedArc, SpeedArc XT, Pulse, and TwinPulse processes, and the optional SpeedUp, SpeedCold, and SpeedRoot upgrades make welding faster, improve quality, and reduce spatter.

Efficiency + highest quality: the Lorch MIG-MAG Speed processes.

Greater speed in MIG-MAG-welding only increases efficiency if quality can be ensured with proper penetration and a welding process that can be operated easily by anyone. 

This is exactly what Lorch has focused on and meticulously developed the innovative MIG-MAG Speed processes that significantly increase your welding speed at outstanding weld seam quality, noticeably simplify the process, and enable unparalleled productivity. 

Perfect integration of the LorchNet and BUS coupling system for all common protocols.

An S-RoboMIG XT series welding system always uses a LorchNet connector. This modern interface ensures reliable communication between different Lorch devices.

The LorchNet connector also optimises connection of the S-RoboMIG XT power source to the robot controller. It serves as an interpreter, translating all signals and information from the internal LorchNet bus system into the robot’s language from one of the common FieldBus or Industrial Ethernet protocols.

All signals relevant for torch control, such as blow-out function, collision protection, and the contact sensor can also be communicated via the bus system entirely. An analogue-digital interface INT-06 for control cabinet installation or power source internal with 42-pin Harting connector is available as an option.



No compromises in operation with all functions for high-end applications.

As a premium product, the S-RoboMIG XT series contains best control and operation, including all functions needed for high-end applications.

The display-controlled user guidance facilitates operation and enables simple process and characteristic curve selection. The control panel is unobstructed, and the user interface clearly structured to start welding on the system right away. The system is additionally equipped with three outstanding speed processes in the XT-Full Process version.



  • “3 steps and weld” operating concept
  • Stepless current adjustment
  • Digital Volt-Amperage-display
  • Simple process and welding programme selection
  • Dynamic control (at Synergic, SpeedArcXT, SpeedPulse XT)
  • Tiptronic job memory for 100 welding tasks
  • Available as a remote version: individual selection of the operating option. In the power source, as a remote control control panel or both on demand

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.

The Lorch RF-06 robot wire feeder.

Lorch’s RF-06 Robot wire feeder is compact, light-weight, and precise, making it the perfect wire feeder for standard and hollow-arm robots alike.

Greater quality, productivity, and profitability for your welding production.

Made possible by digitalisation. Made simple with Lorch Connect.

Data collection has enormous potential. It provides information on every single parameter along your value chain to decisively influence quality, productivity, and profitability of your processes. As a result, Lorch has developed a cloud solution that is as cost-effective as it is intuitive to use, providing the transparency required and helping you digitally master your daily tasks.

Lorch Connect records your welding production data to let you analyse your processes and optimise them in a targeted manner. Add the optional Lorch Connect to S-RoboMIG XT-welding system for a digital overview.

“The flexible Lorch system keeps us on the safe side in the long term. We have increased our speed by up to 40 percent for many weld seams and achieved great savings in the welding cycle and power consumption.”

Philippe Becel

Company head, Stivent Industrie

“It is extremely important for us as a medium-sized enterprise that the operating and adjustment expertise remains entirely in-house. Lorch’s robotics solution has reduced our processing time to a quarter and makes us far more flexible to boot."

Armin Galser,

technical manager, MTS

Q-Sys 2020: Highest quality thanks to precise welding data monitoring.

The compatible Q-Sys 2020 stand-alone solution fully monitors and evaluates weld seam quality entirely as a welding process monitor. This provides fast and accurate welding data recording, controls welding parameters, and identifies defective weld seams. This warrants error-free production.

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