Gasless Mig Welding Wire E71T-11
Features and uses:
E71T-11 is one Gasless flux cored wire mig welding wire. It adopts DC positive connection and is suitable for all-position welding. The deposited metal has good low-temperature toughness and crack resistance for single-pass and multi-pass welding.
Precautions:
(1) In order to prevent the occurrence of blowholes, remove greasy dirt and rust from the base metal before welding.
(2) Since this wire is softer than the solid wire, the pressure roller of the wire feeder should not be too tight.
