Introduction & Characteristics:
FRW-309L is designed for the welding of dissimilar metals such as stainless,mild and low alloy steel. It is used for all position welding to be used with CO2 or Argon + CO2 mixed shielding gases.This wire recommended for high deposition rates in the flat and horizbontal position.
Instructions:
1.The oil stains and rust on the weldments should be cleared away.
2. Designed for welding with CO2 or Argon + CO2 mixed shielding gases
3. When welding, the gas flow rate is generally 20~25L/min.
