Turn on. Weld.

The automatic synergic adjustment simply and reliably gives you perfect weld seams – without any in-depth set up required. This not only saves time and money, but also ensures a consistently high quality to your welding work.

Robust housing.

The housing is highly robust and can be manoeuvred easily with stable handles. Crash protection on the handles protects the display when space is scarce. The slip-proof rubber mat on the top of the housing serves as a practical stowage surface.

Optimum wire feed.

The robust wire feed system with feed rollers tried and tested in the industry ensure a stable, precise, and reliable wire feed. This is a prerequisite for continuous welding and clean weld seams. Thanks to good duty cycles, even long weld seams can be welded quickly and optimally.

Multi-process: full flexibility.

Weld reliably and flexibly - no matter which welding process. With the R series, you don't have to decide. Whether MIG-MAG, TIG or electrode. The R never lets you down.

Maximal work safety.

R-series products effectively protect your welding professionals while ensuring highest safety at work with their three special features:  
1. Angled torch connection 
2. Double gas cylinder safety device 
3. Rolling lock total stop roller
