Sigma One

Produce high-quality welds

With Sigma One, you get the essential programs and functions you need to produce strong, high-quality welds. The high versatility enables you to handle a wide range of materials and thicknesses.

You can increase precision and accuracy when welding both root passes and the additional layers. Sigma One can help you to succeed with your welding projects.

For occasional welding – light use

The lower amperages options for Sigma One are meant for repair, maintenance and other quickly done welding tasks in professional industries.

For the occasional welds and unexpected need for welding. It is great for small workshops or well-equipped maintenance departments.

Faster welding with pulse

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.

For continuous welding – heavy use

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. A team of welders can keep the productivity level at an absolute maximum.

Easy to use for both welders and supervisors.

The graphic control panel is designed to be easy to understand. Users with limited experience with digital welding machine displays will quickly grasp this simple design. It is easy to find and adjust the core welding settings: amps, voltage and wire feed speed. It is great if you want well-known settings presented in a simple, yet visually compelling way.

Intelligent Gas Control (IGC®)

With IGC, the welding machine always uses the right amount of gas for every weld. It prevents over-consumption and gives you long-term savings.

The higher the amperage and the bigger the weld pool, the more gas you need. A traditional valve does not know this, but IGC® does. Gas synergy lines are preadjusted for gas and type of wire. It makes sure that your weld pool is always perfectly protected.

When you always have the optimum gas protection, there will be no holes, pores or impure welds. Reduce the risk of failures created by insufficient gas flow or gas turbulence. Improve the weld quality and reduce your gas bill at the same time. IGC® is an optional feature.
