Here’s what you need to know about flux core welders

How to choose a flux core welder?

As mentioned, there are too many options from different brands on cheap flux core welders alone. But you don’t have to spend the budget on any least-quality equipment.

And that’s where you should know the essential facts to influence the overall welder performance. Make checks for the following points to confirm your ultimate purchase.

1. Efficiency

Mechanical devices can never transform their complete input into energy. And you don’t want to use a cheap one to raise the cost. Lack of info on efficiency is pretty common with flux core. Check the necessary details to determine an approximate idea.

2. Duty Cycle

Electric arc welding involves extreme heat to cause eventual damage. And duty cycle initiates a shutoff for cooldown after a certain temperature. Reasonable welders should provide 3-3.5 minutes of running to follow 6.5-6 minutes of rest.

3. Output

Almost all standard flux core welders generate 50/60 Amp to 120/130 Amp on output. It’s important to note the absorption as well as its input voltage. It’s better to maintain a subtle output to skip interior mechanical issues.

4. Portability

One obvious benefit lies with portability, coming from weight & dimension. The majority of the available models remain within 35 – 40 pounds of weight. Only a minimal number of options can weigh less. Check additional straps on the assembly for carriage.

5. Thermal protection

It’s indeed a must for welders, regardless of the type. You must consider overheating protection while dealing with extremely hot arcs. The inner temperature shouldn’t interfere with its built-in mechanism.

6. Push or pull

Many entry-level welders make the mistake of pushing the weld. The abundance of slag can merely perform its intended function with pushes. But flux core welding actually requires pulling for a precise joint.

7. Skill Level

Not every machine is ready to work with novice welders. Of course, flux core welding seems incredibly simple for almost anyone. Still, you should know the right equipment to match the current skill level.

8. AC or DC

A minor yet extremely useful consideration goes with the output type. And we’re talking about the result in terms of AC/DC. AC isn’t exactly the best way to produce precise welding. That’s where you can keep DC options on your checklist.

9. Thickness

Plate thickness plays an essential part in confronting weld durability. The part tends to struggle with exceeded thickness. Flux core welding can primarily weld 24-gauge or thicker steel. One thumb rule implies further output amperage to allow greater thickness.

10. Wire type

Wire diameter, as well as reel diameter, should meet the standards. Light welding projects require 0.030” wire with a 6” reel. Meanwhile, a somewhat heavier bead will check 0.035” flux wire. However, a limited lifespan of a 6” reel will require regular changes.

11. Control panel

Different levels of adjustment should occupy the design for the customized outcome. Feed speed control can offer up to 10 levels of change with a rotary knob. And the welding speed concerns 4 buttons for sufficient adjustment.

12. Lead quality

Lead remains one of the most neglected facts to depict flux core quality. The trivial fact holds a dramatic level of variation in physical specs. You should check 10’ – 24’ for torch leads & 10’ – 12’ for ground leads.

How thick can you weld with flux core?

It’s essential to understand the extent of welding thickness. A standard 110V – 120V flux core welder to have 0.030”/0.035” electrodes can weld up to ¼”.

What is the difference between flux core & MIG welder?

Flux core welding is suitable for moderately thick gauges. And it particularly concerns the thickness. Better avoid the process for 20-gauge or less steel. The process remains less prone to cold lapping.

Meanwhile, MIG welder can support 12-gauge to 24-gauge steel sheets only. And the actual welding thickness should range between 1/16” to 1/8” or ¼”. It provides a gentle appeal on the welded part.

What can you weld with flux core?

Flux core can explicitly weld ferrous metals only (different types of steels). Almost all kinds of steels within a certain gauge limit can check the flux core welding process. You can’t treat other common metals, aluminum for example.

However, special equipment to combine flux core with MIG can impart further applicability. You can possibly treat aluminum as well as other metal sheets. But there are several restrictions to obtain a satisfactory outcome.

Frequently asked questions (FAQs)

Q1. Is a flux core welder any good?

Ans: Yes, flux core is useful since it’s gasless and if you’d like to weld outdoors. You don’t have to worry about the gas getting blown by the wind.

Q2. Is MIG welding better than flux core?

Ans: Flux core machines are an upgrade and boast of many advantages when you compare to MIG and TIG welders. They are suitable for basic repairs at home and outdoor projects. Unlike the MIG, they don’t use shielding gases such as argon.

Some modern flux core welders run MIG shielding gas; hence they’re versatile. They are also reasonably priced and energy-efficient.

Q3. What can a flux core welder weld?

Ans: A flux core can weld different types of metal, such as steel, stainless steel, carbon steel, and aluminum

Q4. How thick can you weld with flux core?

Ans: The main advantage of flux core is that it can weld thicker metal in one instance. Several factors come into play, such as the power and flux-core wire gauge.

If your house has 115 voltage and 0.35 inches, then it means your machine can weld up to 1/4 inches of thick steel. If your power supply is 220Voltage, then you can weld 1/2 inches of steel.

Q5. Is flux welding strong?

Ans: Yes. Flux core welding creates strong welds and can deliver a maximum of 25 lbs. of wire every hour. A typical MIG welder delivers only 8 lbs. per hour.


Every choice from the expert narrated list can meet the satisfaction from different contexts. You just need to understand the practical requirements to match the equipment specs.
