Spot Welders Buying Guide
Buying a spot-welding machine is a big investment for your workspace and workloads. You must have a budget of around a thousand dollars to buy a spot-welding machine. That is why you have to be wise enough to choose the best welder that will serve all the necessities in your working hour. Here we have tips about buying the best battery spot welder among all the best ones.
What spot are you going to weld?
The first checkmark is if it is a battery or metal joints. Battery welders are small and they don’t use that much electricity. They are small and compact for use on tables. If you are interested in using the welder on metal plates, you should try the bigger ones with big wattage and capacity. They have jaws or most possibly welding guns. You don’t have to buy the big welding guns if you are going only for battery attachments.
Battery welding tools
Battery welding is a big part of the production line and there are some tools and accessories involved in this process. You have to have metal plates and welding tips to use them correctly.
If the stock machine comes with its own accessories and tips, it will be easier to use out of the box. The best battery spot welder will come with sets and a lot of adjustability to use with ease and hassle-free.
If you are buying a welding kit for the first time, you have to make sure that the device is super user friendly. generally, spot welding does not take a lot of time. All it takes is a touch and a moment for healing up.
There are simple and more straightforward spot welders. They have leavers and a switch. You might also use a welder with pedals. You can now engage yourself in making the joints instead of holding the metal and switches at the same time.
Safety should be your first priority
It is the safety that makes all the differences. A power tool should always have a grounded connection so that you can avoid accidental shocks.
A welding machine costs around a thousand dollars and it also consumes a lot of electricity. You have to make sure that the cords are well isolated and they are high quality and provides much safety. Every welding machine should also have a fuse inside so that it does not cause an accident in case of voltage overloading.
Is it portable enough for your need?
A portable welding machine will definitely give you the mobility and versatility that every DIY guy loves. If you have a battery welder, it should be small. Two-armed spot welders might be handy for you if you are interested in taking your welding machine at your client’s place (if you are a professional).
If you have bought the bigger units, it should have wheels that will help you moving around or carrying around.

Make sure that it comes with all the compatible accessories that might not be as well-fit as the third-party accessories.
Advantages of Spot Welding
It has been a lot of changes through decades of metal attachment techniques. Spot welding has become the most popular and easy to do welding that any DIY engineer prefers to get. It has some advantages that we all should know about.
It is safe
Unlike most of the welding methods, this does not need a lot of electricity conversion and that makes it safe for the beginners. Though the electric supply is not forgiving, you will feel safer near lower energy.
Spot welding is also less noisy and does not create a lot of arcs or bright light. you will not need a darkening helmet when you are using a spot-welding machine.
Due to the light and spark emission, TIG or MIG welding becomes tough to nail and hit the right spot and the right place. They might get ruined or the job might become low quality.
When spot welding, you will be targeting a very small area and you won’t have to wear any filter or helmet, this will pick up the precision.
The best technique for the beginners
If you are a beginner in the welding profession or you are trying to do something in your house, spot welder should be the one to get. They use contact voltage to melt metals together. With fewer sparks and dangers, a beginner can easily pick up the techniques of welding.
It is fast and reliable
For battery welding, spot welding has proven to be the most reliable way of welding. With very little power consumption, you will be able to pull out a lot of battery strips welded together. It takes less time due to not needing a lot of arrangements.
It is versatile
If you have a portable universal spot-welding machine, you will be able to know how blessed you are. With two wide arms, wherever they are reachable, that metal is able to be melt and joined together.
Spot welding safety tips
Welding is undoubtedly one of the most dangerous work for the DIY guys. It requires much training and practice to perfectly nail the art of spot welding. You have to deal with huge voltage differences and while welding, you have to overcome the heat that is created by heated metals.
Get enough safety gears for welding
Spot welding is not very daunting like gas welding and sticks welding. You might not need a filtered glass helmet to keep your eyes safe. But it is necessary to keep yourself safe from the burning hot sparks.
Though the whole area of the metal surface does not get a lot hotter than the other welds, you should get a pair of safety gloves. This will save you from accidental touches and accidents.
If you are wearing cotton or wool clothes, it will be a wise decision to cover them up with heatproof wears or safety vests.
Different types of locking jaw pliers are good for holding
Pliers are friends of metalworkers. If it has a locking jaw, it is most likely to be more helpful to hold metal plates unitedly.
As the working principle of the spot welder is to connect two metal plates concurrently by heat while it is already together. You can use the locking jaw to hold them tightly and precisely.
Use better quality sockets and stable electric connection
When you have got a new spot welding set in your hand, go check the quality of the product. Double-check or even overcheck the lines you have got in your hand.
Checking and testing the power cord would be the most important part of welding. If you are welding with stick or gas, it is necessary to get the best quality gas and stick to avoid any kind of accidents. Your weld will be more sustained and won’t decay off fast.
There is no alternative to practice your welding techniques. You will get used to the feeling of slowly melting metals. There will be less doubt nailing your job correctly.
WHAT IS SPOT WELDING?
before understanding the way a spot-welding works, it is necessary to know a basic rule of physics. which is at a very high temperature any Inert matter will melt. Metal is one of a kind and it needs a very high temperature that melts and joins the metal parts together.
Now if we need to know about the basic structure of the mechanism, we have to take a closer look at an ideal machine. They have metal tips or arms that have edgy tips. The arms and tips are all made of copper. Copper has low resistance to the current flow. Two ends or tips have different polarities. If they are placed in contact with one another, electricity flows through the steel and due to less resistive.
In the meantime, the steel melts. The user has to push on the tips to glue them together with the liquid metal. It happens super-fast and does not take more than two to three seconds.
What are the requirements
You have to have a high voltage electricity source to keep it running for a long time. The most important part of this process is the tips. Most of the spot welder has replaceable tips. Before starting welding or going for a batch, you have to buy a new one to start where you have to.
Is it good for everyone?
You will not need much of hassles for using this with your bare knowledge. Spot welding has become popular due to gain mechanical efficiency and timing issues. A beginner can easily get onto the welding job within a very short time and mastering will not need much practice.
This is also good for production-level welding. Most of the automated arms for welding use spot welding for a quick and reliable solution. Most of the battery manufacturing companies buy spare batteries and adds strips using battery spot welders.
Where it works best?
It is most likely to be used in car welding if we are talking about productions. If you are a DIY Engineer and want to attach metal plates together, it will be a must-have home tool for everyone.
DIY Battery Spot Welder
A project at home can truly show you that everything is possible without investing a lot of money on official products. You can easily make the instrument that you might need for professional works. The welding machine is one of them.
If you have a spear microwave oven and a working transformer on it, you can easily shape it out as a spot-welding element. For that, you will need some equipment and there are some instructions that you will need to follow.
Let us see what we need
Wood blocks, sheets, and pieces- you should have mostly flat pieces.
Copper bars- You have to use a handheld saw to cut them in two flat bars
Copper tips- Cut two cylindrical pins from a bar
Bunch of screws- You will need this to connect everything all together
Thick wires- To modify the transformer
Switches- To use as a master key for welding
Prepare the transformer
When you are taking the transformer out of the microwave, make sure that you are doing it cautiously. Disconnect the transformer and pull it out.
This transformer has to be molded to get an accurate rating of electricity.
Now you have to identify the primary and secondary coils of that transformer. The one with more twists will be the secondary loop. We have to replace this thinner coil with thicker wires. 35mm wires will be the best choice here.
We have to cut the core of the transformer and replace the secondary coil with only two to three loops. Also, as a mechanic, we always have to keep in mind that the more the loops, the more it has a tendency to divide out the current flow.
We will be stepping up the current and stepping down the voltage so that it becomes safe though we get in contact with the exposed electricity.
While changing the loop, we must not remove the shunts inside the core. You might need rotating cutting tools or hand saws which will give you clean cuts. Close the core up with a solid welding joint.
Now you have to cut out flat pieces of wood and using the wood as support, install the flat pieces of copper bars. This will be the support and handle to weld.
Make a base using the wooden pieces. place and fix a copper bar on the flat wooden piece. Now you have to put them face to face and connect the top piece with a hinge on one corner.
Cut out pieces of coppers. It will be best if you can cut threads on them and then attach them to the tips copper bars. while you are attaching them on the tip, make sure that the tips come in contact with one another when the hinge gets closed. Connect the secondary coil to those two copper bars and the transformer is almost ready.
Now the electricity has to flow for a very short amount of time. For that, you will find different types of relay switches online. You can also make one for your own using simple components.
You can either use the wooden construction to set up a welding system. If you want to use the machine for spot welding only you can but if you want to use this on battery joints, you have to have different types of tips. Use well-isolated copper sticks and weld the battery tips with metal strips.
Before you go straight for making a DIY welding machine, you always have to remember that this has a lot of risks included in the process and you must be cautious about high voltage and melting heat.
SpotWeld vs Tack weld
These two are the most common and widely used in welding services. They are different in the procedure, instruments, voltage, and operational methods. But more or less, professionals are aware of the fact that they had to know more by doing it more and more. We will be knowing about the subtle differences that make them different from each other.
One of them is a permanent solution
Tack welding is a kind of temporary solution for people who wants their subject of weld to hold on to. You will need welding cables and gases to neutralize the reaction. It has been recommended by the professionals to use them on points to point. You will have to remove the weld after you have finished working on permanent TIG or MIG welding.
Spot welding is a type of permanent solution that is used in most of the car industries. Most of the battery strips are connected together via spot welds. It joints the car sheets one to another permanently. You can not remove or change after you have done once.
Tack welding is a common technique in the field of building construction. People have to make a temporary structure to get things up and settled for a permanent solution.
Spot welding is basically the way metal sheets are joined together. Professionals who work with metal sheets most of the time use spot welding. A portable spot welder can be used to connect the battery ends together and make battery clusters.
Spot welding does not require any kind of gases to seal the solution. The reaction happens fast and it happens in between the contact points.
Tack welding is a Gas Tungsten Arc Welding (GTAW) which obviously requires gases. It makes it more breakable and flimsier yet strong together.
Tack welding needs a bit more time to set up for welding. You have to manage the gun and also use gases to get better results. It takes more time for tack welding. For spot welding, you will not have to spend a lot
Design, quality, warranty, and services are the determinants of the best lithium battery spot welder. battery welding might look small but the precision matter in this case and for that, you have to be nitpicky.
We also have a guide of the best DIY battery spot welder that does not hurt your bank account. You can make yourself one and modify it to your taste. It is always recommended to follow safety tips.
