Frequently Asked Questions:

Which wire do you use for MIG welding?

For MIG welding, the most commonly used wire is a solid steel wire coated with a thin layer of copper. The size and type of wire depend on the material being welded and the welding conditions. For general-purpose welding of carbon steel, ER70S-3 and ER70S-6 are widely used. ER70S-3 is suitable for clean, oil-free material, while ER70S-6 is preferred for metals with more impurities. 

How do I know what wire to use for welding?

To determine the appropriate wire for welding, consider the base metal you're working with, the welding position, and whether the welding will be done indoors or outdoors. For steel, ER70S-3 and ER70S-6 are standard choices. For stainless steel, a wire like ER308L is commonly used. For aluminum, wires such as ER4043 or ER5356 are appropriate. Always match the wire composition to the material being welded and consider factors like the welding current (MIG typically uses DCEP) and gas mixture.

What is the best wire for dirty metal?

For welding dirty or rusty metal, flux-cored wire is often the best choice. Unlike solid MIG wires, flux-cored wires (like E71T-11) do not require a clean surface to operate effectively. The flux in the core of the wire produces its shielding gas, which helps burn through contaminants and offers better penetration.

What is MIG solid welding wire?

MIG solid welding wire is a type of wire used in Metal Inert Gas (MIG) welding, consisting of a solid, continuous strand of wire. It requires a shielding gas, typically a mix of Argon and CO2, to protect the weld pool from contamination. This type of wire is commonly made of mild steel coated with copper to improve conductivity and help prevent oxidation. Solid wires are used in various applications but are most effective on clean, rust-free materials.
