How to Pick Best Flux Core Welders

Flux core welding gives you the optimum amount of flexibility in welding. The electrode can be held in whatever position is comfortable for you and whatever position allows you to place the weld where it is needed.

This type of welding is ideal for outdoor welding because the protected flux works even in windy or drafty areas. It is also great for thicker metals, and for metal that is not pristine.

When choosing a flux core welding machine look for the following things.

Easy to Use Selections

One of the things you need your flux core welder to possess is an interface that is easy to use. You want to be able to select wire speeds and wire feed with a simple adjustment.

Some machines have preset push button selections and some use a rotary dial. Generally the machines with rotary dial knobs have a wider range of selections and settings.

Preset selections make the welding process easier for beginners.

Large number of wire feed speeds

In order to weld different materials and get a clean and professional looking finish you will need to be able to adjust your wire feed speed accordingly. You want to buy a machine that will give you at least ten different wire feed speed settings to choose from.

Easy set up

You want a flux core welder that will be very easy to set up and to put away. You want to be able to set your welding machine up and be welding n less than five minutes. If the setup process is complicated then you are going to be reluctant to bring the machine out.

Lightweight and portable

You want a flux core welder that is lightweight and easily transported. This will give you the freedom to weld in a variety of locations.

Combination Process Capabilities

If you buy a welding machine that can be used as a MIG, a flux core welder and a stick welder then you will be able to do any welding process that you might need to do without purchasing additional equipment.

Useful with a variety of metals

You want to buy a machine that can weld a wide variety of materials. Get a machine that can handle stainless steel, mild steel, steel alloy, copper, brass, metal plate, aluminum and cast iron.

Capable of handling 110 volt or 220 volt input

A dual voltage machine will allow you to work easily in more locations.

How Flux Core Welding is Different than MIG

The real difference between flux core welding and MIG welding is the electrodes that are used during the welding process.

In MIG welding the shielding for the process is supplied by a bottle of gas. In flux core welding the shielding is provided by the electrode and no extra bottle of gas is required.

The electrode for flux core welding is a hollow piece of wire that has the flux contained inside of the wire.

The flux core process is a lot faster than the MIG process. If you are MIG welding you can usually create up to 8 pounds of weld per hour. If you are using flux core you can easily produce as much as 25 pounds per hour.

The flux core process allows you to weld a thicker piece of metal in one single pass than you can usually weld with a MIG process. You should be able to get full penetration on ½” metal so you can make one single pass, and have a smooth and strong weld.

Flux core welding is forgiving when the metal is not perfect or the welding conditions are not perfect. It allows you to work with rusty metal or rough metal in windy or drafty situations. MIG welding requires the metal to be prepared more for the process.

Why  Flux Core Welding?

Flux core welding is a welding process that allows you to get deep penetration when you are welding thicker sections of metal. This type of welding allows you to seam thicker pieces of metal together with a smooth weld and it is much more forgiving if the metal you are using is dirty, rusty, or rough.

Flux core uses a welding machine appropriate for MIG welding. It simply uses a different electrode to create the welds with. Many people like the fact that if they have an MIG welder they have the capability to choose between the flux core process or the MIG process.

The biggest reason why people choose to use the flux core process is the fact that the shielded electrode allows the welder to work in outdoor scenarios where they may be wind that would otherwise interfere with MIG welding.

Welders also like the fact that the flux core process is fast. Most welders can weld ½” pieces of metal together using just one pass when they are using the flux core process.

The flux core electrode stops the welder from having to carry a bottle of shielding gas with them, so it saves set up time and money.

Final Note

Flux core welding has been around since the 1950’s. Welders like the fact that the shielded wire can be used in drafty or windy conditions, because they are free to work wherever they need to. 

This welding process allows you to work with a wide variety of materials, in a wide variety of situations. You can pretty much hold a flux core electrode in any position and it will still create a good weld for you.

These machines make welding thicker pieces of metal easier to do. They can create smooth welds that have less slag associated with them so you finish quicker and have a nicer looking weld.
