Deskripsi
Karakteristik:
LFC-707 is a self-shield flux-cored wire designed for high penetration welding. With good X-ray inspection, desultfuration reduce cracking in welding thick plates, and constrained joints and mediumcarbon steel. It is suitable for flat, horizontal and downhill position.
Aplikasi:
It is widely used for general fabrication and structural weldment where high deposition with good penetration and/or fast travel speed is need.
Catatan tentang Penggunaan:
1. Use DC(-) polarity.
2 .Keep dry while in storage and delivery.
