2. Mophorn 737G Spot Welding Machine -Best For the Price
As a brand itself no doubt Morphorn is an underrated company which has delivered hundreds of best performing electric equipment and spot welders to this market.
With said, if you expect Mophorn 737G Spot Welder take you by surprise you may be at mistake here a bit.
This model by Mophorn is although budget-friendly and ideal for people who have budget constraint it is the welder only for thinner steel sheets of around (0.03 – 0.2 mm).
Accordingly, it suits those who tend to work light with nickel-plated steel strips likewise it performs great with rechargeable lithium batteries.

3. Lenco Autobody Dual Spot Welder – Best for the Money
The professional is on the field now; Lenco Marine is the biggest brand name, known for varieties of category products/units, also one of the popular extravagant brands for spot welders and welding equipment in the industry.
Although the big brand has been surprised their customers with their top line of spot welders, exclusively LencoAutobody Dual Spot Welder has gained popularity as soon as it is launched.
LencoAutobody, the top line product belongs to Lenco Marine, intended and designed to serve professionals and hobbyists through it’s beyond the limit features, aesthetics and unique portable design.
One of the other shocking factors is ten times cost in comparison to the competition but features, performance and highest power won the battle anyway.
Before get on in-depth details addressing, you need to know that Lenco Autobody Dual Spot Welder is more than just an ordinary welder – from the build type, it is indeed a result of smart designing although it weighs around 110 pounds its overall construction makes it easier to move around the workshop.
The advantages which cannot let you take your eyes close to this extraordinary unit includes automatic timer setting, protected control panel, tool storage space and finest streamlined built.
Where the other spot welders 6 inches tong for welding, this technological pro offers two-electrode guns with a 5-foot long cable each attached to it to perform easier and powerful autobody panel weld.
Although this dual spot welder is a real pro and favorite but honestly speaking it is not something ideal for beginners as it does not include spot welding tip so keep this factor in mind when making a purchase.
4. (Generic) Electric Spot Welding Machine -Affordable
However the company Generic is not much known as it is the startup brand started to produce welding equipment and so.
Their produced model of spot welder is the simplest machine without frills design; certainly, it is intended for a single function.
Although the unit is easy to use while the major flaw we think of, is the lacking of additional features which can make it a more desirable option.
Design wise it is fine while functioning involves putting the metal between the tongs and simply lever down to perform weld. Performance-wise it is a fine option while with this unit you can weld the metal sheets of thickness 1/8 inches.
It is a bit disappointing that you need to adjust the unit in terms of differentiating the distance within the tongs’ tips which help you with welding different thickness of metal separately.
But the major problem occurs when the user feels issues while adjustment as the same happened with us during testing.
At the same time, the device requires a plug into standard 110volt electric circuit so the user will not need to worry about enough power supply.
We hardly had any complaints about the performance because it makes small weld rapidly which are not clearly visible. But sill the device lacks extra features and versatility.
5. OEM TOOLS 24891 120 Volt Spot Welder -Most Expensive
Speaking of the company, OEM Tools does not need any introduction as it is one amongst the biggest fish of the market, you know what I mean? Jokes apart the brand is pretty much popular and known as a quality guaranteed brand.
According to the test we conducted we feel it is a larger than the welders we have tested that makes it a bulky machine if you feel it is ok then you’re good to go.
When it comes to operation and performance this unit is quite easy to operate and no doubt a solid device offers good performance.
Also, its adjustable 6 inches tongs provide you enough reach to the working station. The unit can be a good option for both beginners and professionals.
Besides,it’s proposed replacement tips for tongs to help to increase the machine’s life. Also, users can easily swap out current tips simply by unscrewing and screwing the new on the same place.
The spot welder is well functional with the combined thickness of 1/8 inches, can be used on galvanized or stainless sheet steel & uncoated mild.
Altogether this spot welder is on the advantageous side but what really made us unhappy is that its similar-sized competitors on the market are less in cost and size.
It would have been better if they added some standout feature that makes it enough prominent and dominating.
6. Sunkko LED Dual Pulse Portable Spot Welder

Additionally, with the same setting adjustability, the unit performs perfect nickel strip weld with the thickness ranges from 0.05 ~ 0.2mm.
One thing I do not like about the machine is that you need to use microchip for precision controlling current so that you can weld in precision; precision is the most vital part of welding which had to be engineered very well in the unit.
Other than this we are fine with the welding machine as it offers a rare feature of controlled the device using a microcomputer.

Buyer’s Guide – Things You Should Know Before Selecting Right One for You
Before getting on any conclusion, firstly you need to take a look at the details and information we presented.
We have come up with all the basic information and detail regarding spot welding and spot welders to help you enough aware of choosing the right one for you.
Most of the spot welders share pretty similar basic design and operation. But there are some notable differences among different types of spot welders other than the cost of course.
In this buyer’s guide, we concisely address those differences, which help you make the right purchase.
Important Factors to address
- Types of machine
The market is carried mainly two forms of spot welding machines whereas the machine’s design is determined by the work type and workplace.
Type one is considered as stationary machines that are heavy and bulky in size which is harder apparently to operate. However, they are enough powerful and ideal to used for thicker metal sheets as compared to another type.
As all know the benefit of portability, this second type of spot welding equipment is perfect to take with you anywhere.
Portable spot welding machines give you an extra advantage especially for repairing work; certainly, its handy factor is bang on comfortable to go around even farthest.
But you cannot expect portable machines to work fine on the thick materials same as the stationary machine does.
- Power supply
Here comes another major consideration power, the power supply is not just a factor but it is sort of decisive factors that really matter for the machine’s capabilities.
There are many of the welding devices can plug into standard voltage circuit of 110v, although there are some require 240volt circuit.
It is necessary to understand this basic need and manage purchase according to the management of electricity supply you have.
Some stationary welders require sufficient power supply so you will need to prepare a generator of around 400 volts.
- Isolator fuse
It is a feature mainly offered in good spot welders and is a voltage surge protection.
- Spot current
Spot current describes the weld quality of the machine, the higher the spot current number of the machine shows its better weld quality.
- Operating factor
It is better to define as duty cycle while the operating factor of the machine often described on the packaging of the machine.
Having higher operating factor is better as the machine will work the majority in ten minutes and just take 2 to 3 minutes to re-cooperate.
The device with higher current machine offers higher operating factor, together it makes the machine more efficient.
- Secondary vacuum voltage
It defines the quality of priming of the spot welding machine. The measurement of secondary vacuum voltage is taken from device terminals before the application of welding current.
Spot welding process
Mainly there are four terms used for the whole process of spot welding which includes welding, docking, forging and release. The term docking describes when you put two sheets of metals within the electrodes of spot welder.
Welding involves when you apply pressure to both metal sheets, whereas, holding the two metal sheets together is known as forging. Similarly when you release off the pressure and get away the electrodes from the plates is called release.
