Introduction:ER70S-4 is a kind of welding wire with CO₂ or Ar+CO₂ 5%-20% as shielding gas.It has excellent welding performance. It has good one-time shaping performance. When used in argon-rich mixed gas arc welding, the bead is delicate and beautiful.
 
Application:Used for welding sheet metal and thin plates as well as for welding steel pipes.
