co2 gas Welding wire ER70S-6/copper coated welding wire

1co2 Welding wire:AWSER70S-6 0.8mm-2.0mm
2Submerged arc welding wire:2.5mm-5.0mm
3Flux-cored welding wire:E71T-1 0.8-1.6

advantage:

low welding cost

high productivity and low electricity consumption.
easy to operate.all-position welding
very low hydrogen content in the weld and lower nitrogen content.
excellent crack-resistance
little deformation after welding.
wide applicability,suitable for welding thin medium and thick plates.


Co2 welding wire /gas shielded welding wire /mig welding wire ER70S-6

mainly specification:


welding wire is recommended for a wide variety of postional MIG welding wire for mild and alloy steels.It is typically usded in general fabrication,maintenance bridge and structral application.co2 mig welding wire provide low spatter and excellent performance with consistent copper coating ensuring smooth feeding.


Packing
to be made in 5kg/12.5kg/15kg/20kg spool,on pallets then put into 20feet container .we can also make the packing according to buyer request.
