Flux core welders have changed everything for the DIY welder and small shops. Suitable for amateur and professional welders alike, the flux core welding machine is an ideal welding machine. It offers many advantages not found with other welding machines, such as not needing shielding gas and being easier to use outdoors. Flux core welding is particularly great for galvanized steel and metals subjected to rust, and is similar to MIG welding. Many welding machines can even do both.
These inexpensive, yet powerful machines let you weld everything from auto body sheet metal to serious steel plate.
There are so many machines out there, it’s easy to miss out on great features or pay too much for not enough power.
The right flux core welder will depend on the types of projects it’s used for and the types of metals to be welded. We’ve compiled a list of the best flux core welders to help both professionals and hobbyists to find the perfect machine.
Best Flux Core Welders—Buying Guide
A flux core welding machine is one that performs Flux Core Arc Welding, or FCAW. That said, it can easily be confused with a machine used for Gas Metal Arc Welding, like a MIG welder, especially since many machines are capable of both, and use the same welding gun.
We’ve done the homework so you don’t have to. Check out our 5 great little flux core welders.
MIG welders and flux core welders both use the same welding gun as well as similar power to produce the weld. Often, a MIG machine is also capable of flux core welds. The major difference between the two is that unlike MIG welding, flux core welding doesn’t require shielding gas. Flux-Core vs. MIG Welding
