LFJD Automatic Spot Welding Machine

LiFuJunDong isn’t the most renowned name in the spot welding market, but the recent introduction of quite a few premium welders made the users echo their presence. LFJD Automatic is their latest high-quality spot welding machine that has mastered the craft with utmost efficiency.

This one’s mainly a deluxe pulsed argon arc welder that gets the job done in the fastest amount of time.

This device is the ideal tool for someone looking to make special battery packs using 18650 batteries. These kinds of batteries are widespread in electronics and other small appliances, which means that this spot welder can be useful for various projects.

Despite this, the machine’s smaller size makes it unideal for larger products that require heavier welding. With that said, this battery spot welder still does what it can very well.

Overall, the YaeCCC 737G battery spot welder is an incredible budget-friendly machine that offers a lot in terms of convenience and efficiency. Its lightweight frame makes it easy to move about the shop while its sturdy construction means it can handle continuous projects without fail.

Stark Professional Electric Spot Welder 240v

The Stark Professional electric spot welder switches things up from our last entry. This particular spot welder excels in fusing metal plates instead of making delicate electronic repairs and adjustments. The single-phase design and its robust frame make it exemplary in handling heavy-duty jobs in auto repair and detailing.

This particular spot welder features an innovative single-phase design with two large six-inch tongs that can firmly grasp the two plates for welding. The tongs also act as the electrodes for the welding process, and both tongs have replaceable welding points made from high-quality steel. Every purchase comes with an extra pair of tips for your convenience.

Using the welder is simple as can be. All you have to do is be diligent when plugging in your machine. Remember that this particular spot welder is compatible with 220 to 240 volts, so you should always plug it in within that range. At 240 volts, the machine will run at about 16 amps.

Get Stark Professional Welder at Amazon

The Stark Professional 240v spot welder has a duty cycle of 50% at 16 amps, so you’ll get good solid welds without having to worry about overdoing it. The manufacturers claim that you can weld sheets up to an eighth of an inch in width, but with the high input voltage, we’re sure you could push that up to at least a sixth of an inch if not more.

Performing the weld is as easy as pressing down on the lever. The upper tong will drop and securely fasten the two sheets of metal together, then quickly press the switch underneath the level to activate the circuit and start the weld. Although the tongs are secure, we suggest using a pair of pliers or vice grips to hold the sheets in place when welding. It’s just an extra precaution to ensure that you get a clean and accurate weld every time.

One of the best qualities this machine has is its sturdy design. You can see the material’s quality and strength from the welding points to the frame, especially the braided copper wire behind the front guard. These components make this an incredible spot welder for just about any scenario.

If you’re looking for a reliable and portable spot welder for moderate industrial work, then Stark Professional Electric Spot Welder 240v is the perfect device for you. Its sturdy construction and its impressive power output make it well worth the mid-range price point.

Mophorn 737G Pulse Spot Welder

The Mophorn 737G spot welder is another simple, effective, and portable spot welder perfect for a wide array of welding jobs. You can use this machine as a convenient push-up battery welder by adjusting the pressure dial or a precise pedal welder with the accompanying foot pedal.

Every purchase comes with a bunch of components to help streamline your welding experience. The package comes with the welder, a foot pedal, a fixed 18650 battery holder, four welding needles, a hex wrench, and two fuse tubes. As for consumables, the package also comes with 60 nickel-plated strips, perfect for battery pack welding.

Before using the welder, the first thing you should do is install two of the welding needles into the front posts’ slots. These two needles are what will carry the current and do the welding on your desired material. Controlling this machine can be done in two distinct ways: pedal or push-up.

Get Mophorn 737G Pulse welder at Amazon

Push-up welding is by far the more straightforward method between the two and is what we believe to be the best for battery pack welding. Once you set the pulse and current to your specifications, you simply raise your metal to contact the welding needles. The posts’ pressure can be adjusted using the dial on the top of the device—push-up welding ideal for consecutive light welds that you would see when fusing multiple 18650 batteries.

We suggest utilizing the foot pedal to get better power control and more precise welds for any other projects. Keeping close contact with the electrodes without setting the welder off gives you more time to make adjustments before committing to a weld. Using the foot pedal also gives you more control over how long you want to keep the current going, which also helps penetrate thicker materials and achieve stronger welds.

Mophorn also equips the 737G welder with a smart chip that prevents the unlikely chance of overheating. Safety is always an important consideration when purchasing appliances like welders, so having the extra bit of security that this feature affords you is a great thing.

The Mophorn 737G Spot Welder is another great compact barebones spot welder that excels in handling smaller hands-on projects. The convenient push-up welding method is a great selling point for this device, especially considering its reasonably low asking price. We highly recommend this spot welder for small to moderate size projects.

Lenco Autobody Dual Spot Welder

Lenco Autobody gives us a unique spot welder fills our need for a heftier industrial type spot welder on this list. The Lenco Autobody dual spot welder is considerably larger than the other entries on this list. Still, it also delivers much higher amperage, up to 50 amps, perfect for vital spot welds in larger projects.

Each purchase comes with the spot welder on its convenient roller caddy, dual five-foot welding cables, and a 50-foot power input cable. The minimal parts and pieces make it simpler to keep track of and easier to use overall. With no filler material and not gases needed, this spot welder keeps expenditures at an all-time low.

Despite its larger build, The Lenco spot welder gives you a fair amount of mobility. Its cart allows you to move about your workshop with little problem, and thanks to its 50-foot power cable, you won’t need to keep replugging the machine whenever you move it.

The output of this machine allows you to tack carbon steel anywhere from 20 gauge to 12 gauge. The power output of the welder can be easily adjusted using the dial upfront.

Using the welder is extremely simple. Just press the two electrodes against the working material and press the button to activate the circuit. The welding time is controlled automatically with the machine’s solid-state timer. This feature gives you quick and efficient welds without fear of over welding.

A common mistake users run into is that they believe the two electrodes need to be facing each other on the opposite sides of the welding material. You are supposed to use both electrodes simultaneously on two different welding points on the same side. The five-foot cables on each allow you to get into hard to reach spots, perfect for auto-repair or detailing.

The only problem we have with this particular model is that it is slightly bulky compared to the other entries. At 110 pounds, the Lenco spot welder can be quite cumbersome to move around even with its wheels. Despite its weight, the machine still performs exceptionally and should not be looked over.

We believe that the Lenco Autobody dual spot welder is an incredible spot welder that shines in a few key aspects. The machine is incredibly time-efficient thanks to the dual electrodes, sturdy thanks to its robust design, while still cost-efficient since it doesn’t require any consumables to work well.

Stark Professional Spot Welder 120v

The final entry on this list is a variation of a previous entry. The Stark Professional 120v spot welder doesn’t do anything crazy; it is still an exceptionally reliable spot welder, perfect for anyone looking for a simple yet effective tool to keep in your workshop.

This welder also features the simple single-phase design to streamline the welding process further. The double tongs that act as fasteners for your metal are also the electrodes that carry the current to achieve the weld. Each tong is tipped with a welding point, and every purchase comes with a spare pair. These replacement tips are easy to install since these particular welding tips are threaded.

This particular model works with an input of 120 volts and runs at 13.5 amps at maximum voltage. This power output is enough to handle stainless or galvanized steel up to an eighth inch in thickness. This feat is quite impressive considering an eighth of an inch in thickness is nearly the same as its 240v variant.

This particular model operates the same way the 240v version does. All you need to do is place the two fastened sheets on the lower tong’s point wherever you want it welded. Using the lever, slowly secure the two sheets and press the switch underneath the lever.

The compact design of this spot welder makes it easy to maneuver around the workshop without fatigue. You can even operate the machine in awkward angles that would be difficult for other spot welders to manage. The machine’s simple operation makes it easy to execute dozens of spot welds in no time.

The only apprehension we had with this model is that it’s still somewhat weaker than the Stark Professional 240v spot welder. Both the 120v and the 240v versions have their strengths and weaknesses while maintaining the same overall operation. In many cases, we believe that the 120v is sufficient power output and ends up becoming more cost-efficient once you factor in the appliance’s energy consumption.

Outside of the different input voltages, both Stark Professional spot welders are made with sturdy materials and made to last. Both can withstand stringent stress tests and continuous welding without any signs of wear.

With all that said, the Stark Professional 120v spot welder is a quality device that is very much worth your consideration. If you want a cost-efficient, reliable, and portable spot welding machine, this 120v spot welder might be your best option.
