Buying Guide: – Factors to consider before buying the best spot welder for your requirements
By now, you are familiar with the top-rated spot welders for reputed brands in the industry. With the mentioned specs and pros & cons, you must have chosen the most suitable machines for your needs. But, if you are a newbie, chances are you are confused with the spec list. Well, no more confusion now, as we are aimed at cracking the best deal through this best spot welders review.
There are certain factors that one should indeed consider before buying a spot welder. These factors decide whether the chosen machine is worthy of your investment or can fulfill your requirements.
On the other hand, one should never compromise on these factors, no matter whether it is about price or brand value. Some of the essential factors include
1. Choosing the type of spot welders: –
Spot welding works vary based on different applications and needs. One should always choose the machine which is designed primarily to fulfill the appropriate requirements. However, there are five types of commonly-used spot welders, classified based on their build and operation. They are: –
Pedestal Spot Welding Machine: –
Foot pedal-based spot welding machines are for precise welding or for battery packaging specifically. In these models, a fixed vertical frame is fixed to the workpiece in such a way to move in rectilinear motion.
The pressure between the electrodes is maintained easily using the buttons and digital display on the device. Thus, the electrodes can operate automatically, resulting in an accurate spot welding operation.
As you can control the machine and the tips using your foot on the pedal, your hands will be free for precise welding. If you need to work consistently for battery packaging or diffuse thin metal slabs, it is the best way to go. You can do as many welds as possible with less effort compared to others.
Upset Welding: –
These models are also called Resistance Butt Welding machines. You can find these machines with table-top, guides, a stationary and a moving platen and an up-set mechanism. In this type of welding, the ends or welding tips are present face to face to give good contact to the materials in between them.
The electrodes on the jaws press the metals to close together and supply maximum heat to join them at the point of contact. You can accomplish multiple tasks using these spot welding machines as they use high pressure on a large area. The automotive and construction industry finds the best applications of these models.
Seam welding: –
These are the typical spot welding machine with a similar mechanism as that of up-set and pedal ones. It consists of a bed frame, a transformer, and operates using a pressure mechanism. However, the use of an electrode drive system to pack multiple metals makes it a bit different.
Projection welding: –
As the name suggests, a moving jaw is projected towards the fixed jaw with the sheets placed between them. When the temperature rises with the current flow in each projection, the metal sheets get attached. These spot welders are used in mass productions in a manufacturing-based industry or automotive industry.
Handheld welding: –
With such models, you have to hold a set of batteries in your hand to weld them. You can set all the controllable options like pressure, current, and pulse quantity before holding the batteries. In this way, you can be assured of an accurate weld for the battery packages.
2. Duty cycle: –
The duty cycle of a spot welder reflects its potential to withstand the heavy temperature and to support prolonged usage. Mass production and industrial use require consistent performance for long-term performance.
More than 50% of the duty cycle is considered safe for typical welding applications. This means the machine can work continuously for 5 minutes before the cooling process starts to settle the temperature.
No matter which type of spot welders you are going for, make sure to prefer the one with more duty cycles. If you are associated with large-scale manufacturing industry, the duty cycle is the core feature for your needs.
3. Precision in welding: –
Spot welding is more of a delicate welding procedure to weld thin or sensitive metals. Once the welding is done, it is hard to undo it. Thus, precise operation is one of the critical factors for any spot welders.
Pedestal spot welding machines deliver precise welds with foot controls. To ensure accurate outcomes, you need to look for the most controllability features. These include a pressure knob, current and pulse control knob, and adjusting tips or replacement welding tips.
You can ensure accurate welds on targeted metals when choosing a spot welder with maximum controllability or adjustment capabilities. Some brands are pushing the micro computer-operated devices to accomplish such sensitive tasks too.
4. Cables quality and size: –
Spot welders are used mostly in an industry’s workspace with high possibilities of maneuvering. Thus, the welding cable’s quality is crucial when you are maneuvering over a large metal sheet.
On the other hand, the length of both the power cable and welding unit cable is also essential. With long cables, you can just leave bothering about the machine and focus on the welding quality. A long cable is necessary for industrial usage, as you may have to handle a lot of tasks at once.
5. Durability: –
A spot welder focuses mostly on professional-grade applications, and thus, the strength of construction matters a lot. If your spot welder is not strong enough to withstand the metals’ strength, welding will be weak for sure. Make sure to assure the stability of construction and a rugged body of the machine for good welding quality.
Whether you are opting the pedestal-based spot welding or a handheld model, the strength of the rods and the quality of electrodes are quite essential. It is always safe to look for an adequate durability level, even if you are using it for home DIYs at small projects.
6. Portability: –
The size and weight of the spot welding machine play a crucial role in all kinds of applications. A compact and lightweight machine with a durable build is possibly the right choice among spot welders. With such a portable build, you can easily carry the device with you anywhere.
Even if you come across a large-sized machine, look for wheels or a long cable for easy transportation and easy maneuver. But, if you choose a handheld welding machine, size and quality are compromisable to some extent. As you have to just hold the batteries’ package before the welding tips, weight is not considerable.
7. Monitoring and control capabilities: –
When working with high-temperature machines, it is essential to look for proper monitoring features. A spot welder should have a digital wattage meter and a pulse meter to ensure an appropriate outcome. It would be better if you can use the pulse control buttons to regulate the pulse quantity too. However, the best spot welder is infused with all kinds of control options, from the digital display to LED indicators. You can also consider a spot welder having the battery tester or USB ports as a reliable one.
8. Ease of use: –
Automatic settings are more reliable than manual operation unless you have decades of experience with the welders. For proper outcomes and accurate welds, look for a simple process. There are many spot welders out there with a single touch access button.
On the other hand, if you are a professional undergoing mass production tasks, then user-friendly operation is the essential requirement. Go for a spot welder that is packed with all kinds of control features, and once set, it continues further. Well, cooling features and protection features also need to be automated for such operations.
9. After-sales services: –
While buying an industrial-grade machine, after-sales service becomes quite essential. You certainly wouldn’t want your device to lag or deliver wrong results with inconsistent performance. Thus, it is always better to prefer a spot welder with a maximum warranty period.
Availability of service centers should also be assured before preferring a specific brand. With such services on your back, you can just rely on your device no matter whether you are in the workspace or at home.
10. Price: –
Finally, price is an essential yet crucial factor for every buyer out there. You may come across several machines offering different specs at the same price or vice versa. In order to get the best deal with the most compelling features, all you have to do is compare.
Compare all the key specs and pros & cons of the two devices you have filtered out of a bunch of options. However, all the products mentioned above are equipped with best-in-class technology. So, you can rely on the price range as well. But, it is best to compare and buy all the time.
