Copper coated continuous or cut length solid wire for TIG/MIG welding.
CLASSIFICATION : AWS/SFA-5.18 ER70S-7
CHARACTERISTICS :
Copper coated double oxidized solid wire for all position CO2 welding. The special Characteristics are smooth and stable arc low spatter Thin and uniform copper coating ensure good conductivity usedull for high speed feeding
APPLICATION :
Suitable for welding structural steels up to UTS 500 N/mm2 and Carbon steel and low alloy steels for single and malti pass with higher travel speeds compared to others filler metals.
SHIELDING GAS :
Welding with CO2 gas and Ar+ CO2 gas mixture
