This One is great if you just need air

Choose this one if you need your welding machine to breathe air. Just air. No extraordinary features. And you can still serve your sole purpose: to weld. Dedicated welders can carry out efficient high-quality multipass welding. Keep cool through it all with top of-the-line air cooled torches.

One purpose. Weld

Sigma One is a super simple, high-performance inverter which is ideal for busy welding productions where the main aim is to keep the productivity level high. Use it for welding steel structures, prefabrication and thick plates in mild steel, stainless steel and aluminium in the production hall or on-site. 

One purpose
With Sigma One, you get the essential welding programs and functions you need to be able to carry out efficient and high-quality multipass welding. There are no unnecessary refining of the arc, just weld. Use it for root passes and the additional layers.

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.

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