Why does flux core wire Weld thicker metal than MIG?
The difference between MIG and Flux-core is the electrode used and they way the melted metal is shielded from the atmosphere. In flux core welding the filler wire is filled with flux. In MIG a shielding gas is used. In FCAW the flux shields and coats the weld pool. The weld then cools slowly creating a very strong weld.
How to use a MIG welder with flux core wire?

How to weld with flux core?
Flux-cored arc welding uses the heat generated by an electric arc to fuse the base metal at the weld joint area. This arc is struck between the metal workpiece and the continuously fed tubular cord consumable filler wire, in which both the wire and the metal workpiece are joined together to form a weld joint.
What Is Flux Cored Arc Welding?
Flux core arc weldings were introduced in the 1950s. Technically, the introductions of this process were not new. It was just a new type of electrode that could be used on a MIG welding machine. Flux-cored arc welding is a process similar to MIG welding. Both processes use continuous wire feed and similar equipment.
What Are Differences Between FCAWand Mig Welding?
The main difference between flux-cored arc welding and MIG welding is the way the electrodes are shielded from the air.

Flux-Cored Arc Weldings is the most productive of the manual weldings processes! When comparing MIG welding to fluxes core arc weldings, there is a huge difference in the number of welds produced per hour. MIG welders can typically produce 5 to 8 pounds of welds per hour, while an FCAW welder is packing more than 25 pounds of welds per hour.
What Can FCAW Weld?
Welding with fluxes core electrodes has some serious disadvantages when it comes to the weldability of metals. So far, flux-cored arc welding has been proven on most carbon steels, cast irons, nickel-based alloys, and some stainless steel. Unfortunately, most non-ferrous exotic metals cannot be welded, and this includes aluminum.

Flux Core Welding Tips
Before telling you some flux core welding tips, let’s first find out what flux core welding is.
What Is Flux Core Welding?
Flux Core Welding is an electric arc welding process that provides for better weld penetration and can be automated or semi-automated. It’s not dissimilar to traditional arc welding or even MIG welding. However, one significant distinction is that the wire used contains Flux (hence the name), which covers the entire weld.
Flux Core Welding Tips To Weld Outdoors With Ease
Many people have the misconception that stick welding is the only way to weld outside. That isn’t the case now. If you’re diligent and thorough, you can use flux welding outside successfully.
FAQs
Always utilize a drag (pull) technique when welding with flux-cored wire, in which the tip of the welding gun is aimed back at the weld pool and dragged away from the completed weld. A basic rule of thumb to remember whether to employ a push or drag (backhand) technique is: “If there is slag, you drag.”
Conclusion
There you go, some great flux core welding tips to help you weld easily and without any difficulty. If you’re still having some confusion regarding welding tips, read FAQs to clear your mind. Don’t forget the safety part though. Hope we helped you.
Prepare the Metal
Flux core welding is far more tolerant of surface contamination than MIG or TIG processes. Despite this, it’s best to ensure the surface of the metal base is cleaned thoroughly. While tolerance to contamination is useful, rust and dirt can still contaminate your weld.
Set Up the Equipment Properly
One of the most important flux core welding tips is to get to know your welder. In flux core welding, you must use a DC electrode that’s set to negative. This setting is called straight polarity, and it can be adjusted by connections located on the inside of the welder, beside the drive rolls.
Wear Safety Clothing
No matter what type of welding you’re doing, safety should always be a priority. The best way to protect your eyes, face, and body is through safe clothing and equipment.
Choose the Right Wire
Flux core welding often involves using mild steel. Using a versatile wire is one of the best flux core welding tips that one can get. It can be used in various positions and is available in a range of sizes. When choosing the wire diameter, .030” is effective for general-purpose welding applications.
Setting the Voltage and Amperage
It’s important to set the right voltage and amperage for your specific project. How much it requires is dependent on the thickness of metal, joint configuration, welding position, and wire diameter.
Ensure You Have Adequate Ventilation
When welding in confined areas, you must ensure you have adequate ventilation. Welding processes involve several different toxic materials and gases. These can combine to become very dangerous if inhaled.
Always Drag in Flux Core Welding
Dragging refers to a pull technique, where the tip of the welding machine is pointed toward the weld pool and dragged away from the completed weld. Dragging the torch ensures splatter compiles on the completed weld, minimizing porosity issues.
SHOULD YOU WELD BODY PANELS WITH FLUX CORE?
Most people will not recommend welding body panels with flux core. This is due to the thinness of body panels, which can range into some pretty thin sheet metals depending on the car you are working on. Typically FCAW is only recommended over the thickness of 14 gauge for adequate results whereas body panels range between 20 and 18 gauge.
HOW TO WELD ON BODY PANELS USING FLUX CORE WELDING?
Most of the official company websites don’t specify the settings for welding this thin metal. I had to do some experimenting and digging to find out what will you need to weld using FCAW.
WHY IS MIG WELDING CONSIDERED TO BE A BETTER CHOICE FOR BODY PANELS?
If you ask any welder out there, their usual choice while welding body panels and sheet metals would be MIG welding. There is a very simple reasoning behind this, MIG welding does not run as hot as flux-core. During the latter, the wires use more heat as the arc also has to burn the flux inside the welding wire.
FREQUENTLY ASKED QUESTION
There are a lot of places on the internet that warn you about using flux-cored welding with body panels and thin sheet metal but very few of them clearly tell you if and how it can be done. I have tried to compile a list of everything Naturally this will lead to some questions in your head.
What is flux core welding?
Flux Core Welding, often abbreviated as FCAW, involves the use of a welding wire that is similar in many ways to Metal Inert Gas (MIG) welding except for the fact it includes a flux-cored compound within the wire that has the capability to remove the need for shielding gas.
What are the pros and cons of flux core welding?
Several pros to flux core welding include portability, ease of use, versatility, usability outdoors, and the ability to weld through rust. The cons of flux core welding include the cost of the electrodes, the appearance of the weld bead, spatter, and slag inclusions to name a couple . Here you will find a guide to what makes flux core welding so ...
What is 308LFC-O flux core wire used for?
The 308LFC-O flux core wire can also be used to weld 430 series stainless steel.
Why use solid wire over flux core?
One reason why you might prefer a solid wire over the flux core wire is the visual appearance of the produced weld bead. Flux-cored wire electrodes produce more spatter during the process than the solid wires used in MIG welding do.
Why do you need shielding gas?
Other reasons why you need to use shielding gases when welding includes the need to: Prevent excessive splatter. Keep the arc stable. Control the weld penetration into the base metal. While the solid wires used in MIG welding require shielding gases, flux core wires do not require the use of shielding gases.
What is the best gas for MIG wire?
Gas-shielded MIG wires need to be used in conjunction with a supply of low-cost shielding gas, either 100% Carbon Dioxide (CO 2) or a mixture of Argon (Ar) & Carbon Dioxide. A typical mixture includes 75% Argon with the rest being Carbon Dioxide.
How much wire can a flux core electrode deposit?
According to Tulsa Welding School, a flux core electrode is capable of depositing up to 25 pounds of wire per hour. A MIG electrode, deposits 8 pounds of wire per hour when it is performing at maximum efficiency.
