Copper coated gas shielding welding wire is suitable for 100% Co2 or Argon&nixed gas protective welding with excellent mechanical performance such as fast melting rate,high depositing efficency, stable arc,little spatter,and beautiful seam.It is suitable for all-position welding.
The serise of welding wires can be used for welding low carbon seel and low alloyed steel strcuture,such as ships,vehicles,bridges and bulidings construction.
This serise of welding wires has different kinds of packing,such as different types od plastic spools,metal spools,pail packages and straightened wire in plastic tube.
