Wprowadzenie
Zapewnia bardzo wysokie prędkości spawania i zwiększoną odporność na pękanie wodorowe i porowatość, nawet w przypadku stali zabrudzonej lub zawierającej siarkę. Zalecany do spawania jedno- i wielowarstwowego stali niestopowej i niektórych stali niskostopowych w zastosowaniach nie wymagających wysokiej udarności.
Zalety
- Bardzo wysoka wydajność stapiania
- Zwiększona odporność na pękanie wodorowe i porowatość
- Miękki łuk, minimalne nadtopienie materiału rodzimego
