KFT-X309L Flux Cored TIG Rod

Description

KFT-X309L
Shielding Gas: 100% Ar
KFT-X309L produces slag to protect the reverse side of the root pass from oxidation by the atmosphere and saves the cost for back shielding gases and gas purging downtime including the setting time for gas purging jigs

Classification


Application and Features 

• KFT-X309L produces slag to protect the reverse side of the root pass from oxidation by the atmosphere and saves the cost for back shielding gases and gas purging downtime including the setting time for gas purging jigs
• Suitable for welding dissimilar materials such as mild steel to stainless steel

Welding Position


Welding Instruction

- Formation of key-hole during welding is very important in order to supply slag onto reverse side bead
- The melting rate of flux cored wire is higher than that of solid wire due to flux addition. The speed of wire feeding must be higher
- Only for root pass in single-side welding, not for cover pass

Application
- Suitable for welding dissimilar materials such as mild steel to stainless steel
