ГАЗОЗАЩИТНАЯ СВАРОЧНАЯ ПРОВОЛОКА ER70S-3

ER70S-3 welding wire is used for single-pass or multi-pass welding, butt welding and fillet welding equivalent tensile strength mild steel or low alloy steel structures, such as vehicles, locomotives, pipelines, lifts, bridges and so on. Particularly it is suitable for low current high speed welding sheet steels.

Welding Position: F, H, HF, OH, V

Type of Current: DCEP

Notice:

To avoid rust the wire must be kept in dry condition and keep the package in good condition also before welding.
The surfaces to be welded must be cleaned away impurities of oil contamination, rust, moisture and so on.
To prevent blowhole in weld metal, the arc voltage should be higher and the arc length should be 4mm-5mm.
The welding conditions mentioned above for reference only and it is better to do a welding procedure qualification according to project before put it into formal welding.
