Why Use Spool Gun?

A spool gun is a specialized welding torch that is used to feed a small, spool-shaped wire electrode to the welding arc. This can be helpful in a variety of situations, such as when welding aluminum or other materials that are difficult to feed through a regular welding torch. Both professionals and DIYers use spool guns for welding softer materials like aluminum. This type of material is vulnerable to deforming issues.

A spool gun allows you only feed a few inches. This reduces messy issues. Additionally, this welding equipment gives you the flexibility to weld with minimal restriction.


  • There are several advantages to using a spool gun for welding. One of the main benefits of using spool gun is that the small size of the spool gun and its wire electrode allows for more precise control over the welding arc and the weld bead. This can help improve the quality of the weld and reduce the risk of mistakes or defects.
  • Another advantage of using a spool gun is that it can help reduce the risk of wire feeding problems, such as bird-nesting, which can be common when using a regular welding torch. The spool gun also allows for faster wire feeding, which can help increase the speed and efficiency of the welding process.

Overall, using a spool gun for welding can provide a number of benefits, including improved control, reduced risk of wire feeding problems, and faster welding speeds. This can make it a useful tool for a variety of welding applications.

What You Consider (Buying Guide)

You need to consider following aspects before buying a spool gun.


You may find your workpiece far from your welder machine. In case of mig welding gun you must have faced the problem. The same applies to spool gun. If your work piece is far from your machine then you would need to reach that with welder.

That’s why spool gun cable length is important. The longer the cable the easier to reach the welding site. So, make sure your gun cable is long enough. In our case we have mentioned the spool guns from least 9ft to highest 20ft. You may choose Miller spool gun for heavy duty welding as it comes with 20ft long spool gun.

Wire Size

In Mig welding filler wire is an essential element. Welding different thickness of metal depends on the size of wire you are using. For example for welding thin metal you may use 0.23″ wire but to weld thick metal like 1/2″ steel or aluminum you must use more than 0.35″ wire to perfectly melt the metal and join them strongly.

So in case of spool gun selection, you must consider the wire size the spool gun can handle. Some spool gun handle only 0.23″ wire and some can run 0.30-0.35 and other sizes. The more variation of size the spool gun can handle the better.

Spool Size

Spool is the rounded store of wire that contains mig wire in it. The spool usually rests on the top of the spool gun. It hold the mig wire and run it through the gun nozzle to workpiece. Spool contains a lot of wire at once in it that enable the welder to weld continuously without worrying for relocation of wire. Some spool gun have as large as 4″ spool size and some comes with less than thet. The larger the spool size the better.

Feed Rate

A feeder is attached to spool gun. When you insert the wire into the spool it goes to the feeder and through the feeder it reaches to the nozzle where it melts the metal and joins the workpiece together. Beginner models offer 8-9 meters feed rate while pro levels can reach upto 13-14 meter. For heavy projects the higher the feed rate the better weld it will be. For quick melting 13-14meters feed rate is recommended.


Spool gun comes with some other mig accessories. For example a spool gun contains conductive nozzles, plug for connection to welder, wire feeder inside the gun, gas tips, mig welding filler wire, connecting rods and gun head. Gun head is usually made of brass coated with Teflon as brass melting point is highest 1083°C. Also spool gun comes with a long cable that connects the gun to welder box. Most of the spool gun comes with a beautiful box that protects it from external pressure.

Durability & Guarantee

And lastly, look up for guarantee & warrantee of the spool gun. Sometimes even good brands spool gun can be damaged or come in distorted. If the product offers guarantee & warrantee you may keep yourself risk free. Most of the products offer guarantee. Despite check the products manual and products description first.

Do Spool Guns Come With Welder Machine?

Spool guns are usually sold separately. Some brands may offer welder machines with spool guns if you buy them a package. But, they don’t sell a vast amount of welder machines.

Spool guns don’t last long if you continuously weld the entire day. That’s why most manufacturers sell them separately in bulk quantities.

Are Spool Guns Universal?

Spool guns don’t have any universal type. Their size will vary from one brand to another. In fact, a single brand may have different sizes of spool guns.

Before buying a spool gun, it is crucial to check the compatibility of the gun with your welding machine. Otherwise, it will be of no use.
