Product Description

Equivalent to Lincoln 780 welding flux 
SPECIFICATION: EN760 SA AR 1 88 AC H5  AWS A5.17     F7A0-EL12 F7A2-EM12K 
Submerged arc welding flux

Description: 
1.It is an agglomerated aluminate- rutile type flux.
2. Grain size: 14 to 60 mesh
3.Basicity: 0.7( BIIW).
4. Performance: 
A. Easy to deslag. 
B. Sulfur removal, phosphor removal and anti-rust. 
C. Fine appearance of weld (even in the narrow gap of deep slope entrance). 
D. Metal welding seam: Good plastic toughness, low hydrogen content diffusion and fine properties of cold, heat and crack resistance. 

Usage:  
1.LPG Cylinders 2.Pressure Vessel 3.Boiler
Cautions: 
1. The oil contamination, moisture, iron rust and other foreign substances must beremoved from the welding joint. 
2. It is better to weld under direct current. 
3. Welding flux must be baked under 250-300°C for more than 2 hours
Before usage.
