AWS A5.18 ER70S-6 is a low alloy steel gas shielded welding wire, protected with pure CO2 or Ar+CO2 Gas. Stable arc, low spatters, excellent fabrication weldablitily and low sensitivity of weld gas porosity can be obained during welding.It can be used for all position welding and has a very good welding performance especially with large welding current range.

Applications:

Suitable for single-pass and multi-pass welding for structures fabricated by carbon steel and 500MPa grade low alloy steel, such as vehicles, bridges,construction and mechanical structures etc.

Instructions:

A. Suitable for using shielding gas at the speed of 20-25 liters per minute.

B. Windshield must be set up in the welding zone, due to gas porosity may be caused by strong wind.
C. Wire extention should be 10-20mm if the current range is under 300A and if above 300A, 20-25mm.
