Welding is a difficult process and needs to be carried out safely and accurately. To do so, you need a welder that will allow you to weld with precision. Flux core welding involves the use of flux-core wires which are coated in iron oxide to give the molten metal something to stick too, allowing it to flow into the joint with ease.

Conventional MIG welders use solid wire, which is good for making welds in thick material but doesn’t work as well in thinner material. Flux-core wires are designed for use in thin material and can also be used for joining thicker materials together.

If you need to buy a welder, it is important to take some time to research your options before you purchase one. You don’t want to end up with a machine that isn’t going to provide your with everything you need. Thankfully, it is easy to find the best flux core welder on the market today.
