SM-100 is a 0.3Cr-1.7Ni-0.25Mo-alloyed, bare, solid wire for the GMAW of high strength steels with low-temperature impact toughness requirements.

Characteristic features include excellent start properties, trouble-free feeding at high wire speeds and lengthy feed distances, a very stable arc at high welding currents, extremely low levels of spatter, low fume emission, reduced contact tip wear and improved protection against corrosion of the wire.

① Use with 100%Ar or Ar+2~20%CO₂gas.
② Flow quantity of shielding gas should be 25ℓ/min. approximately.
③ Use the wind-screen against wind.
