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 useful for high
speed feeding.
APPLICATION : Suitable for welding structural steels upto 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
