Whether you are a Hobbyist amateur or a professional who needs a versatile welding solution, a Flux core welder is the best way to start your Welding journey. It’s the best way of cutting your welding cost as it doesn’t require any external gas supply to shield the molten filler metal. Only an hour with a Flux core welder is enough to give you a proper grasp on perfect welding expertise.
Choosing the best flux core welder for the money can be daunting as there are tons of features and options to consider. Before you lock your target on a random welder, read through it to the end to decide which one will serve you the best. From an expert point of view, we’ll help you decide the features you must not skip in a Flux core welder.
Advantages of flux core welding:
A flux core welding system comes with tons of advantages, especially if you are planning for outdoor welding. Here are the main advantages of a flux core welder that you can relate to.
- Weld outdoor:
When you use a MIG welder, it will require you to have an external supply of Gas to shield the welding while it’s cooling off. While using gas to shield the welding outside, the airflow may manipulate the gas shield and weaken the joint. However, when you are using Flux core welding, it comes with the included tubular wire with a flux compound inside. This compound makes the shield itself, and the air cannot manipulate that shield. So, the Flux core welding system allows you to weld outside, especially if you are a professional who works on the go.
- Cut the extra cost and hassle:
When you need an external cylinder of Gas, it comes with extra cost to purchase and refill it once finished, which is mandatory with MIG welding. This comes with some extra hassle as well; you cannot carry it anywhere without a trailer. If you use a Flux core welder, you can easily carry it around like a side bag and get to work anytime without the extra cost of purchasing the Gas.
- Manufacturing and Industrial usability:
The flux core welding system creates a great penetration over thicker joints, which is important for industrial usage. If you are planning to purchase a welding system for manufacturing steel products with a great finish and strong joint, you can give it a shot. The deposit rate of the filler metal with flux core is way more than any other welding system. A MIG welder deposits up to 8 pounds of filler on the joints; a flux welder does it with 25 pounds, which is great for heavy work.
- Use in all positions:
You cannot use any type of welder to weld in any position from any given angle. With a flux core welder, you can weld from any angle, vertically or overhead. All you need is a little expertise to know your angle and a proper ventilator.
However, using a Flux core welding system will produce a lot of smoke and fumes, you need to use a ventilator for that. You need to clean the left-behind slags after welding with the flux core welders, which is not necessary with MIG welders.

How To Choose a Flux Core Welder Machine?
Before buying a Flux core welder, there are tons of features and amenities you should consider. Let’s talk about the things you should look for in a flux core welder before choosing one.
- Multipurpose usage:
The multipurpose use of a welder is important if you work on different types of metal. You cannot weld all kinds of metal with flux core welders; you may need MIG welding as well. If you are a professional, look if you can use the machine both with Gas for MIG welding and without Gas for Flux core welding.
- Budget range:
Getting a better machine requires a better budget, a double purpose (MIG and flux) welder will be pricier than a single purpose one. If you are a beginner and don’t need MIG welding with the gas operation, go for a flux-core welder.
- Current consumption:
Current consumption is a big consideration because it produces the necessary heat and Arc to weld. A 110 V machine is powerful enough to get most of the work done with great quality. However, if you need more power from the machine and have the budget, go for a 220 V one for industry quality weld.
- Wire consideration:
Flux core wires come with self-shielding flux inside to protect the molten weld from the nitrogen and oxygen around, so you don’t need Gas for protection. MIG welders come with filler metals that need external Gas for protection from oxidation.
- Metal thickness:
When we work on different kinds of metal, the thickness of the metal is important as the welder penetrates it to join together. The flux core welder is more compatible when it comes to welding thin to thick metals, while a MIG welder doesn’t do a great job with thin metals.
How To Use a Flux Core Welder & Safety Tips?
If you want to master the art of welding with flux core wire, you have to know all the crucial parts of this welding method. From the preparation of welding to the ending, along with a perfect start, you must follow these essential steps.
- Prepare the welder:
Prepare the welder with the recommended settings, make sure you have set the polarity negative for flux core and set the wire feed speed the same as the current heat.
- Prepare the metal:
Before starting to weld, clean the base metals if there is any dust, rust, or stain and make sure you are welding a clean piece of metal for the best weld.
- Take it steady:
While welding, make sure you are running the gun in a single motion, direction, and weave. Don’t juggle around or go too fast or slow, and it will make your weld worse.
- Safety gears:
In metal works, your Safety comes first, wear welding helmet, gloves, glasses, flame-resistant jacket and boots, long pants. Have proper ventilation for flux-core welding as it produces a lot of smoke and fumes.

Frequently Asked Questions:
Can I use flux core wire in a MIG welder?
Yes, you can use a flux core wire in a MIG welder unless the manufacturer built it only for Gas-shielded operation and prohibits you from using flux core wires.
Do you push or pull flux core welding?
With the flux core welding method, you always remember a line: “If you get slag, you drag.” Unlike stick or TIG welding, flux core produces slag, and you should always pull the gun instead of pushing it.
Can you weld sheet metal with flux core?
Yes, you can weld thin sheet metal with flux core wire using the right welding machine that has housing for a wide range of wire feeding and more control over speed and heat, such as the SUNGOLDPOWER MIG Welder 140A
