Kemppi X5 FastMig


Extraordinary Arc Welding Productivity

Experience next-generation steel welding with X5 FastMig, an industrial multi-process welding system developed by Kemppi in collaboration with professional welders. Available in 400A and 500A models, the X5 FastMig is a versatile arc welding powerhouse that is built with energy-efficient inverter technology. Reliable, non-short-circuit ignition (Touch Sense Ignition) paired with Wise special processes minimize spatter and create high-quality welds you can count on.


The clear, graphical panel is fast to adopt and easy to operate. Well-balanced Flexlite GX welding guns with excellent cooling enhance the welding experience even further. The modular setup and wide range of accessories bring flexibility and efficiency to welding production processes.


Made in Finland, the X5 FastMig is built to last. Robust, injection-molded plastic casing protects the equipment from outside blows and challenging work conditions. Top-loading wire feeder design ensures ergonomics and safety when changing heavy filler wire spools.

Automated accuracy

Graphical 5.7” TFT screen panel is impact-resistant and displays all the needed information clearly without abbreviations. Welding parameters are set automatically by only adjusting wire feed speed. Memory channels are available to customize and save personal settings. In addition to automatic parameter adjustment, a manual panel with traditional two-knob operation is available with limited welding processes and functions.

Unique user experience

*Includes WiseSteel special process and X5 Work Pack 1-MIG with 17 welding programs.
