Buying Guide


Before you think of the budget for buying a new flux-core welder, start by researching the average prices of models that catch your eye. If you’re done with that, you can move onto planning your budget.

Welders which have more features will be more expensive. However, you should narrow down the features you need in a welder. That way you can escape the high price and still get away with a stellar pick.

Another option is purchasing models with useful features that you may not need currently, but you can use it in the long run. That’s a good investment. It’s worth considering going for that rather than buying a cheap flux core welder that would have to be replaced soon.

Types Of Output And Metal

DC and AC welders have different outputs, so it’s understandable we want to spare a few sentences on them. Welding stainless steel is more the domain of DC outputs. On the other hand, AC welders work better with just steel. Generally speaking, the AC output isn’t really the most compatible option for flux core welders.

When it comes to the types of metal, one of the flux core welder’s biggest minuses is the fact that it doesn’t weld aluminum. If this metal is important to you, you may consider buying a multi-process welder.


The dilemma of this section is whether to buy from a reputable brand or take the risk and choose a less-known company. The quality of the welding machine comes first, so in some cases, the name of the brand doesn’t essentially mean that their model is the best one there is although it may influence that.

Then again, we’re talking about a welding machine that doesn’t come for free and that you don’t buy every day. Sometimes buying from a famous brand means great after-sale activities, trust, great warranty conditions, and other extra features.


The density and durability of the lead in the welder affect the whole period of usage. What’s more, it makes the whole welding experience more enjoyable and provides the user with confidence. That’s if the length and quality of the lead are satisfactory.

To be more precise, it’s advised that ground leads should be from 10′ to 12′. For the torch lead, the range goes from 10′ to 24′.

Of course, this can be understood more like a personal preference rather than a rule that’s set in stone. Users say that longer leads mean you have more freedom while being mobile.

Density Of The Plate

It’s very important to think of the plate density when buying your next welder. This ability is basically a part of the welding tasks and projects at hand. That’s because it determines whether you’ll be able to weld denser materials than usual. Take your current welding job or similar foreseeable ones in the near future and determine how thick you’ll like to weld.

The welding community has one pretty universal rule. It states that higher amperage means you’ll be able to weld much thicker materials. But consider that no two welders are exactly alike. So, it’s best to try a welder out or check out the reviews before drawing your conclusion regarding the plate density.

Frequently Asked Questions (FAQ)

What can I use flux core welding for?

People use this type of welding when they want to weld dirty or otherwise known as impure metals. An electrode creates the welding arc, so it isn’t a complex technique. In fact, it’s very similar to MIG welding. That’s why sometimes you can find the exact same equipment for both MIG and flux core welding or at least similar parts.

What does the flux stand for in the world of welding?

The role of the flux is to clean the material from the impure elements. Oxidation is a great example. It’s an integral part of the welding process when dealing with these specific materials. When the materials are in a purer form, there is not much left to remove from the metals.

Is gas used when working with a flux core welder?

The self-shielding type of flux core welding has gas protection capabilities. They come into effect when the flux wires burn. For this reason, gas tanks or other providers aren’t needed. This immensely makes the welder more portable and easy to move around. It isn’t seldom to find gas used in flux core welding though. Carbon dioxide and its mixtures, for one, are pretty well-known. The same goes for Argon. Don’t limit yourself to those. Others are used a lot, too.

What are some of the benefits of practicing flux core welding?

It isn’t one of the most popular welding processes out there for nothing, right? There are numerous positive things about flux core welding and welders. We’ll try to be as concise as possible. For starters, it’s very suitable for outdoor tasks and projects. That’s because sometimes you can go without shielding gas. Unlike other techniques, the flux core can work through very dirty metals and materials in general. Moreover, it’s considered to be one of the simpler types. Beware that users still need plenty of welding skills to successfully handle flux core welding. It’s also known for the speed. For many high-speed tasks, users often rely on outer gas. Additionally, there are plenty of improvements in the deposit rate. This rate is higher when compared to other welding types like MIG, for instance.

Is a MIG wire compatible with the flux core welder?

As we previously established, they’re pretty similar kinds of welding. So, the short answer is yes. Opting for flux core means that you can use it even when it’s pretty windy. With that being said, the ability to penetrate is heightened.

Is warranty vital when it comes to the best flux core welder?

Try your best to find models that have warranty conditions. A pro tip is to look for the period or how long will you be covered and compare that to other models and the industry’s averages. Also, make sure you check what’s included in the warranty. If you think all of the terms are suitable, then you can seriously think of getting that model.

A Final Word

Overall, there are many things to look forward to when getting a flux core welder. Starting from the numerous adjustments and user-friendly interface to its small size and weight, everyone can utilize them. Of course, there are certain downsides, especially for more serious welders and professionals. That’s why you should carefully weigh everything in and decide what you want. We hope this complete guide helped you with this.
