Flux core welding wire E71T-11

      E71T-11 is a self-protected flux-cored welding wire. It adopts DC positive connection and is suitable for all-position welding. Deposited metal has good low-temperature toughness and crack resistance and is used for single-track and multi-pass welding.

Precautions:

(1) In order to prevent the generation of pores, remove the grease and rust on the surface of the base material before welding.

(2) Since the wire is softer than the solid wire, the pressure roller of the wire feeder should not be locked too tightly.
