Flux Core Wire : Thermatech TM-71T-1C

FLUX CORE WIRE : THERMATECH TM-71T-1C

The THERMATECH rutile type flux-cored wire suitable for welding Grade 500 MPa steel.   It has a good technical properties for all-position welding, stable arc, few spatter, low fume, easy for slag removal, smooth wire feeding, low tip abrasion, excellent mechanical properties, high impact energy.  Ideal for shipbuilding, steel structure, marine engineering, bridges, machine structure.

Recommendation:
（1） Use CO2 as the shielding gas, the purity must be over 99.8%, and the flow rate should be 20-25 l/min.

(2)  In order to avoid gas porosity, please remove the oil, rust and water from the surface of the base metal before welding.

(3)  Polarity:  DCEP

(4)  Some actions should be taken to prevent from wind, if the wind speed is beyond 2m/sec.

(5)  The wires do not need drying. Nevertheless, they must be stored in dry environments, and be used up in two days after opening the sealed package.
