MWA Ni55
For joining of all weldable cast iron grades to themselves or to low carbon steel alloys.
Unique "Bi-Metal" core Ferro Nickel electrode with extra strong arc drive to penetrate contaminants
· Extra strong arc drive facilitates joining in all positions.
· High efficiency weld metal transfer totally eliminates electrode overheating.
· Excellent performance on poor quality porous castings.
MWA Ni55適用于將焊接所有鑄鐵以及鑄鐵與碳鋼的焊接。獨特的“雙金屬”芯鐵鎳焊條，具有超強的電弧驅動，可穿透污染物。
? 超強的電弧驅動，適用于全位置焊接。
? 高效的焊縫金屬轉移完全消除了焊條過熱。
? 即使在質量較差的多孔鑄件上仍具有優異的性能。
