YAWATA YM-28
For Mild Steel and 490 N/mm High Tensile Strength Steel

Welding of mild steels and 490 N/mm2 high tensile strength steels for automobiles, rolling stocks, electric appliances, machinery, air conditioners, light gauge steels, pipes, steel frames, bridges and ships.


Characteristics


YAWATA YM-28 is a gas metal arc welding wire to be used with CO or Ar+10~50% CO shield gas and assures stable arc, less spatter and satisfactory weldability even with a low current of less than 200 A. Welding of thin plates, especially in vertical downward position, is easy. 
With CO shield gas, arc is stable, spatters are less and bead is beautiful in a wide welding current range.
