E71T-1 1.0/1.2/1.4/1.6mm Flux Cored MIG Welding Wire
Flux Cored Arc Welding Wire (FCAW) AWS A5.20 E71T-1, is used for
welding structures made of carbon steel and low-alloy structural
steel with tensile strength higher than or equal to 490MPa. Most
widely used for welding some key structures like shipbuilding,
mechanical manufacture, pressure vessels, boilers, petroleum
machinery, chemical machinery, hoisting machinery etc.
Our advantages is stable arc, little spatter, less smoke; higher
deposition efficiency; excellent welding performance; easy
restrike.
Confirm to standard:

Notes:
1.Adopt degreasing and rust cleaning process before operate.
2.Shielding gas flow: 20-25L/min when welding
3.Extension: 15-25mm
4.The humidity of welding wire storage should be less than 60%
5.Storage period: Vacuum packaging less than 1 Year, other packaging less than half year.
