Frequently Asked Questions (FAQs)

1. Does flux core wire weld good?

The LINCOLN ELECTRIC NR-211 flux-core wire is a good quality reel that, when welding, cools quickly to keep heat out of your project. It also produces very minimal spatter. The slag has good coverage but is easily removed, making cleanup a breeze.

2. Which is better .030 or .035 flux core wire?

The 0.035” cored wire offers slightly more welding power, provides a higher heat input into the metal, and better penetration. Compared to the 0.030” this thicker diameter is used in similar environments. But with a higher flux content, it can better withstand windy conditions.

3. What is flux core welding wire used for?

Although more expensive than solid wire, flux-cored wire could help you gain productivity. Flux-cored wire typically has the ability to handle the welding of dirtier materials that may have higher levels of rust, mill scale or oil.

4. Is flux core welding as strong as MIG?

Is flux core as strong as MIG? Both MIG and flux-cored wires make very similar strength welds, and if the joint is properly welded, there is not a significant difference in strength between the processes.
