High amps. High simplicity.
Sigma Core is a simple welding machine with the core functions you need to weld - also at high amps. It is ideal for welders who demand simplicity in advanced welding. Use it for welding steel structures, prefabrication and thick plates in mild steel.
uncomplicated & effortless
you get the most necessary options you need to produce great welds. No complicated software or unnecessary gadgets. Any welder, no matter the level of experience, will have no trouble adjusting the Sigma Core and start welding right away.
Minimising the technology gap
Sigma Core minimises the gap between earlier generation welding machines and modern day welding technology. It does so by offering an improved arc, which again improves weld quality. It is a more energy efficient solution that consumes less power and gas for an optimised production. Add the optional function Intelligent Gas Control to your Sigma Core and reduce your gas consumption even further.
Great welding performance
The high duty cycle enables you to weld for many hours without any de crease of currents or compromising weld quality. A team of welders can keep productivity level at an absolute maximum.
A cost-effective solution
Great welding performance and modern day welding technology ought to be accessible for all kinds of welding productions. Large and small. High-tech or not. It calls for a cost-effective solution. This is it.
The Core of welding
This is the core of welding. And nothing more. It holds the most essential elements and no unnecessary features or gadgets. Choose a compact design with air cooled torches if you are supposed to be right next to your welding machine at all times
Simple to the Core
This is simple to the core. It holds the essential parameters you need to weld. Trust that it will follow welders who are moving around in the workshop. Separate the wire feed unit from the power source while welding large steel structures. Keep cool the whole time with top-of-the-line air cooled torches.
Graphic control panel
The graphic control panel is intuitive to navigate and easy to use for both weld ers and supervisors. It will contribute to making your daily working procedures efficient.
Visually compelling
This graphic control panel is designed to be easy to understand for all users. 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
