Get things done
Max out.
Continuous welding.
The high duty cycle enables you to weld for many hours without any decrease of currents or compromising welding quality. Weld as many meters per day as your tasks require. With a large team of welders, you can keep productivity level at an absolute maximum.
Intuitive control panel.
Improves working procedures.
Be on top of things with a graphic control panel that is intuitive to navigate. It is easy to use for welders and supervisors. Time saving features such as short cuts and locked settings, will contribute to making your daily working procedures more efficient.
Use the pulse.
Produce more.
Improve productivity even further with pulse process. The low heat input and spatter-free pulse welding lowers the risk of damaging the steel. The process gives you a better control of the weld pool and a better weld.

Migatronic welding functions
DUO Plus
DUO Plus technology automatically gives you better control of your weld pool. It reduces heat input and ensures a perfect weld bead appearance. Set your average currents and DUO Plus takes over. Several cooling periods during a weld are visible in the shape of neat droplets which come together in a beautiful weld seam.
Intelligent Gas Control*
IGC® Intelligent Gas Control technology prevents over-consumption of gas and gives you long term savings. With weld pools always perfectly protected, you increase the quality of each weld. Make sure that all your welding machines are equipped with IGC® Intelligent Gas Control and save money every day. Your investment will quickly pay for itself.
*Not included – must be purchased separately.
Control panel
Be able to see clearly
The high peak brightness in the display makes it easy for the user to see and adjust settings in dark or dimly lit spaces.
Keep your gloves on
The buttons are designed to be big enough for welders to adjust and fine-tune settings wearing their gloves.
Safe from spatter and dirt
The robust protection screen can withstand weld spatter, dust and impacts that it will be exposed to in most workshops and production halls.
Torch
MIG-A Twist FKS400, 4 meters
Included
Large flexibility, easy to use. Turn the swan neck 45° in both directions step-by-step at intervals of 15° and be able to use the correct working posture in all welding angles. It is equipped with double cooling chamber for extra efficient cooling of gas nozzle.
