Welding THIN Material with Flux Core

FCAW | Flux Core

In this episode, we demonstrate how to run a larger diameter electrode on thinner material. Most people would probably run .030 or .035 diameter flux core for 1/8" material.

 What if I told you, you could actually step up to a larger wire and increase your travel speed and therefore reduce material distortion? Thats exactly what we are doing today. You see, when we run a smaller diameter wire, we have to travel at a slower rate which puts additional heat into the materials. By stepping up to a larger diameter, we have to run more amperage, but we also get to travel much faster. This allows us to decrease the heat input because we are spending less time making the exact same size weld. 

So next time you have some thinner material, and you are using flux core, try stepping up the wire size and see how much better you can control distortion. Try it and let us know how it goes. Until next time, Make Every Weld Better Than Your Last!
