Customer Reviews for VEVOR 737G Pulse Spot Welder 0.2mm Battery Welding Machine 110V Battery Spot Welder and Soldering Station Portable Pulse Welding Machine for Battery Pack 18650 14500 Lithium Batteries

Used Spot welder to attach a new battery to circuit board. Unique tool would have cost and taken a long time if sent to manufacturer. Time saver to have.

I mis-ordered a110v welder instead of a 220V, called shipper, explained the situation, the welders passed each other in the exchange. I would buy from this guy again.

Pas assez d’ampérage pour souder correctement des bandes de .2 d’épaisseur. Au final je ne l’utilise pas. Je me suis fait un spot welder avec un relais timer et un relais de démarreur.

Works very well for .15mm nickle strips. Did a few hundred welds so far with no trouble. I have not used the charger part. If you are making packs larger than 4p I would recommend getting a unit that has a welding pen attachment.

I have three different types of these unit and are FANTASTIC machines and do a great job... Bought all of my machines from same seller and very happy with them....

This unit is everything I expected and more. Of course, I just received it a few weeks ago, but I have used it and I’m very happy with the results. I was pleasantly surprised the unit came with a very, very long Roll of nickel plated strip. The manual was disappointing - poor translation. Fortunately there are many YouTube videos that fill that gap. I wouldn’t hesitate to purchase another unit from this manufacturer and wished they made it more convenient to purchase accessories like the handheld electrode unit for larger battery packs.

Works well, super easy to use. Led illumination makes lining everything up easy. Simple to use. Would recommend.-MA

It took care of assembling the replacement battery pack on my cordless vacuum, but it did take some tinkering to adjust the electrodes just right as the arms are not precisely mounted and allow the electrode spacing to change from one weld to the next. I read reviews on similar products tripping breakers and took precautions to us a 20A breaker with the plug just 4 feet away from the breaker to avoid troubles. It would be helpful if they provided guideline setup values. I found I needed to turn the dial to full power and use the double pulse for 69 ms each and keep the electrodes clean to spot weld 0.006" [0.15 mm] nickel strip to the batteries and 0.018" [0.46mm] nickel plated steel to the strips.

This is a great product and a great value for your money. I purchased it to repair some power tool batteries I had. Great product! -Tristen C.
