For safety reasons, anode stubs must be heated up to at least 100ºC (180ºF) to remove any traces of water or vapor - a potentially dangerous issue that also deteriorates the quality of the welded joint.
The Kanthal® high-density power radiating system ensures that any object prior to contact with liquid iron is brought up to 100ºC (180ºF), eliminating any risk of explosion.
Higher quality of welded joint
A perfectly dry stub contributes to a homogeneous welded joint free of porosity, ensuring minimized voltage drop over the thimble.
3-4 times more efficient
Open burners with atmospheric air mixture consume approximately three to four times more gross energy compared to electricity.
