(Flux Cored Stainless Wire)
▶︎ Characteristics:
LFC-704 is a self-shield flux-cored wire. It featuresgood slag removal and friendly to manage variant weld joints by longer sticking out. The welding for heavy machinery, large construction component is appropriate also stiffens in large building.
▶︎ Applications:
It is widely used for site general fabrication and structural.
▶︎ Notes on Usage:
1. Use DC(+) polarity.
2. Keep dry while in storage and delivery.
