説明
特徴
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.
アプリケーション
It is widely used for general fabrication and structural weldment where high deposition with good penetration and/or fast travel speed is need.
使用上の注意
1. Use DC(-) polarity.
2 .Keep dry while in storage and delivery.
