5 Best Spot Welders For The Money in 2022

Last Updated on May 2022

Spot welding is used for welding overlapping pieces of metal through pressure application and supplying an electric current to the metals that need to be welded together. The thickness of the metals that can be spot welded ranges from 0.02 inches up to 0.118 inches. The pressure point applied by the copper electrodes provides a steady welding point.

The elemental equipment needed for spot welding consists of the workstation that includes the welding power supply and the weld head to which the welding electrodes are attached. The welding electrodes are made of copper for its good conductive ability.

You will want to obtain a spot welder if you need to weld metal sheets to each other. You will need some tools to help you with all the menial aspects, especially if you have a lot of small pieces to weld to each other. Spot welders are a professional tool that is used by welding professionals, but it is not that difficult to learn and become proficient at it. The best way to learn spot welding, or just welding in general, is to learn under controlled supervision of a professional welder.

There are many safety specifications involved in the welding trade, and they need to be very strictly adhered to. Don’t worry, though; welding is within everyone’s grasp. Anyone can learn how to weld, even if it is only to do your repairs at home. If you put your heart, effort, and time into it, you can learn to weld, too.

There is a wealth of different types of spot welders out there, and it is a good thing to get a little bit more informed about the specifications and features of each, so you make an informed choice when choosing one for your specific needs. Selecting the right tool for the job can sometimes be challenging, especially if you have to curtail the salesman’s selling skills and enthusiasm.

We will take a look at some of the more regularly used spot welders available for the DIY hobbyist and the professional welder.

Spot Welders Buying Guide

Let’s briefly take a look at the considerations you need to make and information you need to know when it comes to picking a spot welder and using it to the best of your (and its) ability. If you keep this info in mind when choosing, you might end up making a better choice that will satisfy your specific needs even more efficiently.


Price is, of course, one of the biggest reasons you will either buy a spot welder or skip it and move on to the next product. Prices are different depending on the brand and what the spot welder can do. Make sure you’ve budgeted according to your needs – these welders can sometimes be pricey, but in most cases, they are worth every penny spent.


To ensure that you have peace of mind with a purchase, most brands will offer some form of warranty. Make sure to check what kind of warranty you will get from the welder you choose so you won’t end up feeling like a fool should something go wrong.

What to look for

Spot welders can be very reliable and give high-quality welds – something that all of us would want.

In some cases, though, you might have to remove or tear solder joints. That will most likely happen if you’re using your welder in projects that involve auto repair or lots of sheet metal with spot welds. This is when a good welder will stand out from the rest. You will be able to cut around the repair with ease and save much more of the original metal.

How Does Spot Welding Work?

If you’re looking at buying a spot welder, you should know how they are used. You might be an expert and already know. In that case, you can skip over this part. If you’re new to spot welding and want to know as much as possible before jumping in, you will benefit from what we have to say here.

Spot welding comes into play when you have two pieces of metal that you want to combine so that you will have a thicker piece of metal to work with. It is a type of resistance welding that forms two (or sometimes more) pieces of metal together.

In most cases, these welders are used in the car industry, but many hobbyists and a variety of manufacturers also find them useful. You can even find the odd artist or two who make use of spot welders to create exciting pieces of art.

While welding, your welder will create what is called thermoelectric heat, which will be applied to the metal in areas that are called circular points. Copper alloy electrodes will typically be used because it can pass electric currents very well. Depending on the welder and how much pressure you apply, your welds will be something between about three and 12mm in diameter.

Advantages Of Spot Welding

As with any welding, there are positives and negatives to using this method. The biggest positive (by most people’s standards) is that, with spot welding, you will get superbly durable welds. When you need welds that are made to last and reliable, you will tend to make use of spot welding.

  • You do not have to get extra metal weld materials for spot welding, because this method uses electrical currents that go through the attached electrodes. All that is required is an electrical power source. Of course, this will also help you save on equipment costs if that is a motivator for you.
  • It doesn’t require extreme heat either, so you won’t have to stress about burning the rest of the metal you’re working with.
  • Spot welding is an excellent way for beginners to learn about welding because these tools tend to be very easy to use. That doesn’t mean that they shouldn’t practice before working on important projects, though. You still need to be sure that you are using the welder correctly, or you could just as easily mess up.
  • Speed is another consideration that makes spot welding popular. With spot welders, you will get your work done quicker, and these products are mobile so you can take them wherever you need to, provided there is electricity to power it.

Disadvantages Of Spot Welding

  • It should be noted that spot welding is not effective on all materials. Low carbon steel – titanium, nickel alloys, and stainless steel – are the most common options that are great to work with.
  • In general, many people will find that spot welders can be tricky to maneuver. The position of the electrodes will often influence how limited you are. Angles and odd shapes aren’t exactly great friends of spot welders.

Safety Precautions to Always Keep in Mind

You must always make a point of reading the safety instructions and the user’s guide of your welding machine. This is true for all the different kinds of welders on the market. If you follow the tips and guidelines provided by manufacturers, you’re off to a good and safe start. [ Read our full guide on safety equipment]

The electrodes will pass the heat, and you risk getting burned and possibly starting a fire when you use a spot welder. Always make completely sure that the electrodes are cool before you place them on a surface that could be flammable. Remember, better safe than sorry.

Do not forget; you should wear gloves at all times – that is one of the first and most basic rules.

Like any welder, spot welders make sparks, so always ensure that you are wearing suitable eye and face protection. Also, never look directly into the light that is produced when using a spot welder.

It is possible that electrodes can become stuck while you’re welding – you want to avoid this mess of a situation. Electrodes can do this when they are not aligned properly or when the force is just too low. Remember to check this regularly. A dirty work environment can also result in electrodes sticking because a metal surface can easily be contaminated. You should always make sure that your space and equipment is clean before you weld.

Too much heat can also be a reason for electrodes to get stuck, so keep an eye on this as you work, as well.

A precaution you may want to take before welding metal together is to add corrosion protection to them. You can use bonders and sealers or even primers or finishing paint coats. This will make your work much more manageable.

Test alloys before welding metals together

This is to make sure you’ve got the right settings on your spot welder. Before starting your work, use two pieces to test – weld them together and then check if they’re adequately welded by using a hammer and forked chisel to perform a destructive test. This way, you can test the strength of the weld.

What about single-side resistance spot welding?

You may wonder if you can use this approach because spot welders are tricky to move around and not suited to different odd angles. However, this isn’t a good option.

In most cases, you will have to use the double-sided method. Instances in which single-sided spot welding actually works are very rare. If you need this kind of approach, you may find that you will be better off using a different welding machine.
