But if you’re in the market for something more portable and also TIG capable, then the Forney Easy Weld 298 Arc Welder should be right up your alley!
A flux core welder is a welding machine designed to utilize the Flux Cored Arc Welding technique or “FCAW” for short. So, the real question here should be: what is FCAW? Well, and let’s break it down.
FCAW is categorized under the Arc Welding process because it creates an electric arc between the wire electrode and the metal you’re working on. However, what makes FCAW special is that it uses a consumable tubular electrode wire with a flux embedded in its inner core.
This formed arc will heat up both metals (base metal and filler metal) beyond their melting points. The molten metals will then mix, settle, then solidify to attach together all your workpieces and produce one entire piece.
In FCAW, the welder provides a continuous feed of filler wire into the metal pool to make sure it’s uniform. This electrode wire is introduced to the welder via an automated wire feed unit that’s typically equipped with knurled rollers. These rollers ensure a secure hold on the wire without flattening or damaging it.
As you’re welding, the added flux will burn because of the high heat, generating a burning cloud flux that’s responsible for isolating the weld from the air. Preventing the exposure of molten metal to air keeps the weld from deforming and becoming weak.
The general concept of maintaining a constant feed is similar to MIG welding (Metal or Inert Gas Welding), you can even own a welder that simultaneously supports MIG and FCAW welding. But the true difference comes from the use of a flux core wire, as well as the absence of gas shielding equipment, which makes FCAW a more portable and economical option.
Flux core welders are extremely popular among welding beginners as well as experienced professionals in the metalworking world thanks to its apparent ease of use and reliable performance.
Now that you know what a flux core welder is and how it works, it’s time for you to better understand the features you need to look for before making a purchase.
You’ve probably read these words a whole bunch of times throughout our article or while viewing flux core welders online. The duty cycle is a percentage value that expresses the operation capacity of a flux core welder.
To put it simply, the duty cycle tells how long you can keep your welder running before it needs to cool down for 10 minutes. So basically, the duty cycle is a measure of how long you can use your welder at a time, which is particularly important if you often work on larger projects or you want to weld thick metals that require multiple passes.
For example, if a flux core welder has a duty cycle of 35% at 60 amps, this means you can use it to weld for 3.5 continuous minutes at 60 amps output of power, after which you’ll need to shut the welder down to cool down for 10 minutes before you fire it up once again. Generally speaking, the higher the value of the duty cycle, the more expensive it costs.
If you’re familiar with TIG or stick welders, then you know how they maintain a fixed amperage throughout their operation. But for flux core welders, the voltage is what should be kept steady instead, because this type of welders adjusts its amperage according to the speed of the wire feed.
This is also the reason why flux core welders typically offer flexible amperage ranges that you can easily adjust, allowing them to efficiently meet the different requirements of your projects. To put things into a better perspective, the more heat you want to use, the higher the wire feed speed you’ll need, and consequently, the higher the amperage output required. Notice how the voltage was never mentioned as a varying factor.
Most flux core welders available in the market operate on 110 volts or 115 volts, this is the standard voltage input of wall outlets in almost all households. Such voltage generates about 140 amps output, which is plenty of power to weld 24-gauge mild steel up to ¼ inches maximum thickness.
That being said, if you’re looking for a flux core welder to work on thicker pieces of metal, you’ll need to pay extra for more powerful models running on 220 volts input.
There are 2 main types of flux core welding (FCAW): Gas-shielded (FCAW-G) and Self-shielded (FCAW-S). You should determine what type of shielding you’ll be using before buying a welder because each type requires an electrode wire flux core of a unique design to work properly.
FCAW-S utilizes a flux core electric wire that produces a protective cloud to surround the molten weld pool as you’re welding. The purpose of this cloud is to shield the hot metal from exposure to atmospheric oxygen and nitrogen, preventing any reactions from happening and preserving the integrity of the weld.
FCAW-S saves you the extra cost of gas shielding equipment, which is a plus for welders on a budget. Since there’s no additional equipment required, this type is also very portable.
FCAW-G, on the other hand, employs flux-cored electrode wires that rely on shielding gas (for example, pure carbon dioxide) from external cylinders to protect the molten welds from reacting with the atmospheric gases. These high-pressure gas cylinders are the same ones used in MIG welding, where a regulator controls the introduction of the shielding gas.
Despite the added cost of cylinders and gas shielding equipment, FCAW-G provides a fast deposition rate which is why many workers prefer this type of operation.
As for polarity, flux core arc welding typically uses the current type DC (Direct Current) where one end is always positive and the other is always negative. An example of DC is the current flowing from a car battery.
The polarity is usually DCEP when you’re using a large electrode. This means the electrode is positive while the metal workpiece is negative. However, if you’re using a small electrode to weld a thin metal sheet, then you should change the polarity to DCEN where the electrode is negative and the metal sheet is positive.
To switch polarity, you’ll find the control buttons to adjust this setting on the welding machine itself (not the welding gun).
You’d be surprised by the number of people who forget to check the size of the welder before buying it.
Granted, flux core welders are usually compact (even more so with a budget under 200 dollars), but different brands and models can still have varying sizes that you need to consider. You don’t want to spend money on a welder, only to find that it doesn’t fit in your workspace.
To avoid such hassle, make sure you accurately measure your workstation, then compare the numbers with the dimensions of the flux core welder you’re planning to purchase.
One of the most crucial aspects of a flux core welder is the safety features it offers. You’ll be working with many hazardous elements including electricity to power the unit, heat generated by the unit, cables to connect to the wall outlet, as well as the weight of the machine itself. Each factor poses a risk of an accident, so imagine combining all of them at the same time!
To protect the user from getting injured and the welder from being damaged, manufacturers incorporate certain safety features such as cooling fans, air vents, and thermal overload protection systems.
Cooling fans and air vents have pretty much the same job. They aim to dissipate excess heat away from the welder to keep it running at decreased temperatures to avoid overheating. When it comes to budget options, almost all flux core welders have either air vents or cooling fans.
Thermal overload protection systems are present in the more sophisticated models of affordable flux core welders. If you accidentally operate your welder for too long, or you dangerously breach the capacity of its duty cycle, the thermal overload protection system gets triggered to shut down the unit until it’s cooled down enough for safe use once again.
Additionally, some flux core welders come with ground clamps to securely fasten ground cords and prevent tripping.
The case that houses the welder plays a key role in its overall durability. It protects the delicate electronic components inside from being damaged in case you drop the unit or something falls on it.
For maximum protection, you want an all-metal case (stainless steel is usually the go-to option here). Some manufacturers combine PVC with metal to make their welder more lightweight for better portability.
This is a very common question among newcomers (even some more experienced welders may confuse the two techniques), so let’s set the record straight. Flux core welding and MIG welding are pretty similar as they both utilize filler wire that’s continuously fed into the weld. However, there are a couple of major differences between the two.
For starters, MIG welding uses a regular wire, not a flux-cored wire. Here, shielding of the welded metal is done via shielding gas from external cylinders containing pure carbon dioxide or a mix of argon and carbon dioxide.
Due to the absence of flux, MIG welding produces cleaner welds that are generally less messy so they don’t require as much post-weld polishing. MIG welding also gives off less toxic gases.
Flux core welding, as we mentioned above, utilizes flux-cored wire to shield the metal during welding. This makes it the superior choice for welding outdoors since it resists the effect of wind and airflow. Flux core welders are also way cheaper than MIG welders, so they’re better suited for people who are just starting out.
Now that you’ve learned the primary difference between MIG and FCAW welders, you may find yourself wondering if you can just switch the regular wire of MIG with a self-shielding wire and use your MIG welder for FCAW.
In most cases, the answer is yes, you can use a self-shielding flux-cored wire in a MIG machine. However, you’ll need to also change the polarity of the unit from DCEP to DCEN.
Using a carbide scribe, mark a line on the metal and cut using a metal-specific saw or hacksaw. To get precise welding results, it’s wise that you first clean the metal with a degreaser.
The next step in the preparation process is to grind or file a small bevel along the edges that you’re welding. This will help the weld to penetrate more deeply. However, you need to be careful not to go overboard. If you do, you’ll end up burning through the metal as you weld.
Flux core welding is a fairly simple, hassle-free technique to learn and master, but this doesn’t the process is guaranteed to go totally smooth. You may encounter some hiccups along the way, so you should be prepared for it. Following the tips below, and with a bit of practice, you can easily avoid common FCAW issues to achieve the weld quality you desire.
In theory, you can weld aluminum with a flux core wire, but in practice, you’d need a specialized type of wire to make it happen. To date, such a wire doesn’t exist, so the actual answer to this question is no, welding aluminum with a flux core wire isn’t practically possible yet.
MIG and aluminum stick is your best bet to weld aluminum without TIG.
There’s a variety of reasons why your flux core weld may develop wormholes or worm-tracking.
The first thing you should check is moisture residing in the flux core wire spool. Wet conditions or increased humidity around your weld can also result in wormholes. Additionally, operating your welder at a voltage that’s too high can cause such issues, so consider recalibrating your ratios.
Typically, a flux-cored wire is self-shielding, which eliminates the need for external shielding gas. In this case, the wire creates a flux cloud that protects the surface of the weld from reacting with air. However, there are certain types of flux-cored wires that require shielding gas, particularly for FCAW-G.
In any case, most budget flux core welders don’t support the input for shielding gas.
Generally speaking, a flux core machine can weld thicker metals than a MIG welder in one pass. The thickness your flux core welder can tackle depends on two main things: the gauge of the flux core wire and the power input you’re running through the unit.
Working with the basic setup for at-home welding; 115 volts power input and 0.35″ wire, you can weld steel up to ¼ inches thick. If you up the power to 220 volts, you can weld ½ inches thick steel or more.
When it comes to flux core welding, you should pull the weld because there’s much slag produced from the high-intensity arc created by the flux-cored wire. Moreover, you should maneuver the welding handle to work at a 25-degree angle by lifting it just off the surface of the metal. After that, slowly pull the weld across the seam of the weld.
