It’s important that you get several things correct before you start using your wire welder. The wire begins to feed, the gas begins to flow, and the arc starts.

It’s important to note that when you are welding with a MIG setup, your wire welder uses solid wire because the gas protects the weld puddle.įlux core is the easiest way to begin using a wire welder because there is no gas cylinder to set up. So, it’s not necessary to use shielding gas with flux core like you would use with MIG. When an arc is created, the flux melts and acts as a shield from the atmospheric gases that will contaminate your welds and cause porosity. You can also choose not to use a gas bottle with your wire welder, and if you don’t have the capability to hook up gas to your welder, then you’ll have no choice but to use your wire welder with flux core wire.įlux core wire is a hollow wire that is filled with an agent called flux. Overall, starting out with a wire welder using a MIG setup is the best way for beginners to learn because you can easily see the weld puddle, unlike the flux core process. The weld bead with a MIG welder is smooth and very nice when done correctly, and there is no slag to chip away. The advantage of using your wire welder as a MIG setup is that the welds produced are much nicer than with flux core wire. If you’re wondering what shielding gas is when using a wire welder, it’s used to protect the molten weld puddle from atmospheric gases that will weaken the weld if the weld puddle is exposed. If you choose to use it as a MIG welder then you will have to get a bottle of 75/25 (argon/CO2), or straight CO2 so you have shielding gas provided at the weld puddle. When you buy a wire welder you will have the option to buy one that you can hook up a gas tank to, or you can buy a wire welder that uses only flux core wire (gasless).Ī word of advice if you’re a complete beginner to welding wanting to learn how to MIG weld…Ĭhoose a wire welder that has the ability to hook a gas cylinder up to because you can use it as a MIG (Metal Inert Gas) setup, or use it as a flux core welder. So, a wire welder is a little bit more complex to set up and get running right than an arc “stick” welder, but once you get it set up the process of welding with a wire welder is pretty simple. Unlike a stick welder that uses a long “stick’ electrode, a wire welder uses either MIG welding wire or flux core wire. In fact, the simple welding process that a wire welder provides makes it the perfect welder for beginners.Ī wire welder has several components that you need to know about before actually making your first weld. A wire welder, also known as a MIG welder or a flux core welder, is a semi-automated welding process.
