Instruction and Application: Ultra-low carbon stainless steel tungsten electrode arc welding wire, low electrode impurity, metal mechanical properties and weld ability.It is suitable for welding of stainless steel, such as 309S (06Cr23Ni13) type austenitic type. It can also be used as the transition layer or bottom welding of carbon steel or low alloy steel.

Notice:
1.The welding consumables surface rust, oil and other impurities to be clean.
2.Each layer is controlled below 150℃.
3.The operation is appropriate to the short arc, arc length control in 1-3mm.
