AWS A5.18 ER7OS-6
EN 440 G422CG3Si1
JIS Z3312 YGW12
CWB ER495-6 W48

Typical applications

 Widely used in the fabrication of auto parts, truck bodies, heavy equipment and farm implements. Also commonly used for HVAC duct work, structural applications, pipes, steel castings or forgings, shaft build-ups and general shop fabrications.
Mild steel wire for welding of mild steel and 490MPa tensile strength materials.

Characteristics on usage

  • Suitable for high speed welding of steel sheets by short circuiting transfer in all positions.
  • Stable arc and low spatter generation.
  • Flow quantity of shielding gas should be 20 liters /min in general.
  • Use a wind-screen against wind.
  • Keep the distance between tip and base metal within 6 ~ 15mm for 250 Amp. and under or within 15 ~ 20 mm for more than 250 Amp. of welding current.
  • Applicable to mixture gas for welding.
