I have tried to find the best 5 spot welders, which are trending on the market. After extensive research I found that most of the spot welders are made by Sunkko, which is a popular brand name to manufacture a wide range of welding machines and equipment.
Spot welding is also known as resistance spot welding. It comes in the electric resistance welding category, which is good to weld sheet metal products. The welding process involves the use of copper alloy electrodes for the welding current concentration.
The top 5 spot welders are:
SUNKKO 737G+ Battery Spot Welder
Handhold YaeCCC 737G Battery Spot Welder
SUNKKO 709A Battery Spot Welder
Sunkko 737U Battery Spot Welder
SUNKKO 737G+ 4.3KW High Power Spot Welding Machine
SUNKKO 737G+ Battery Spot Welder
Sunkko 737G+ has been selected as the top spot welder in the best 5 spot welder reviews because it is a great pulse welding machine for 18650, 14500 lithium batteries. Please make sure that the battery pack works with Nickel strips 0.35mm.
Sunkko is a popular brand name for making battery spot welders, so please check Sunkko 737G+ as well.
This spot welder by Sunkko has a good design and impressive welding function, which are great for improving the efficiency of battery pack welding process.
Additionally, you can perform welding process using various welding methods, which are optional. And there is no welding limitation of the battery pack size.
SUNKKO 737G+ Battery Spot Welder also comes with soldering function that lets you perform soldering in 300° C temperature with great efficiency.
Good thing about this Sunkko welding machine is the intelligent and integrated temperature sensor and great cooling capability. So the temperature sensor and cooling system work according to the internal temperature of the machine.
This Sunkko brand spot welder gives great welding performance because it can handle welding thickness range from 0.03 to 0.3 mm while the nickel welding thickness is from 0.03 to 0.15 mm.
Performance Improvement Possibility There are three ways to improve the performance if you use this spot welder:
Welding current adjustment (one to eight level optional)
By adjusting pulse quantity from 2 to 18 (optional)
By pressure knob (pressure can be regulated between copper welding rods and nickel strip)
Handhold YaeCCC 737G Battery Spot Welder
The second spot welder I have selected, which is Handhold YaeCCC 737G spot welder. This welding machine comes with various advantages and features for the smooth spot welding. The YaeCCC battery spot welder is made keeping precision current in mind. Yes, you will be able to use micro-chip for controlling precision current for the greater welding accuracy.
Yaeccc is another name for good quality spot welders, please check YaeCCC handhold battery spot welder as well.
On the other hand, you are able to select various level of current in the 0.5 pulse increment. This way, you will be able to weld more conveniently, safely and efficiently.
Handhold YaeCCC 737G Battery Spot Welder lets you weld nickel strip within 0.05 to 0.2 mm thickness because it comes with dual pulse mode selection and 0 to 99 level current setting.

The good thing about this spot welding machine is the affordability and performance. Yes, it is an affordable spot welder that can be purchased in the price range of $250.
On the other hand, this is a feature-rich spot welding machine. It comes with various impressive features that directly contribute to its overall welding performance. The Sunkko 709A welder gives you the option of pulse selection from 2 to 18, which is undoubtedly huge. Other impressive features are: foot pedal, temperature regulation, pressure regulated head, current regulator and fixed/spot welding capabilities.
Since you are able to increase the welding current so it is very useful for the desired welding performance at the time of welding thicker nickel strip.
Pros
Foot pedal is included while most spot welders don’t come with a foot pedal so it is really a plus point.
Great pulse quantity adjustment feature for the spot welding ease.
Cons
The welding pen is of poor quality.
Some users complains that the welding performance is not consistent.
Sunkko 737U Battery Spot Welder for 18650 Lithium Batteries
Sunkko 737U is another affordable welding machine that can be purchased in less than $200 price range. Such low price seems very good and very competitive price on the market where you can rarely find a performance oriented welder in the $200 price range.
This Sunkko brand spot welder is very suitable for welding 0.05 to 0.2 mm nickel plated steel strips. And since it can also be operated on the battery power so it greatly works with 18650 and 14500 lithium rechargeable batteries.
In case, you are using this spot welder then one plus point arises here is the welding performance improvement. By adjusting the welding current level, you can surely improve the welding performance. However, you have to adjust the current level according to your requirement and use the same setting for the repetitive welding tasks.
Please make sure that this spot welding machine is not made for welding materials such as copper and aluminum. It is a good welder for welding pure nickel, nickel plated steel, and nickel plated iron, iron and other alloys.
