Frequently Asked Questions

Q: What is the primary difference between AWS ER70S-6 and other carbon steel wires?

AWS ER70S-6 contains higher levels of manganese and silicon, which act as deoxidizers, providing better weld quality and less porosity compared to standard wires.

Q: Which welding processes are compatible with this copper-coated wire?

It is highly versatile and compatible with MIG (GMAW), TIG (GTAW), and Shielded Metal Arc Welding (SMAW) processes.

Q: How does the copper coating benefit the welding process?

The copper coating improves electrical conductivity, reduces friction during feeding, and protects the wire from atmospheric corrosion.

Q: Can this wire be used for shipyard and heavy engineering projects?

Yes, its high tensile strength and impact resistance make it specifically suited for tough environments like shipyards and construction sites.

Q: What diameters are available for the ER70S-6 welding wire?

We provide a comprehensive range of diameters from 0.6mm to 1.2mm to suit various thickness requirements of base metals.

Q: How do I store these welding wires to prevent degradation?

Store them in a cool, dry environment. Our plastic metal spools are designed to protect the wire, but keeping them away from extreme moisture is recommended.
