737g Battery Spot Welder 1~2 Pulse For 18650 Soldering 50-800a 1.5kw 110v

I had read many of the other reviews and I was expecting to have problems with the spot welder, but I was hoping to get lucky. When I removed the spot welder from the shipping box two of the screws fell out. These weren't the small screws that held the case together, it was two of the longer screws that held the transformer in place. I was obviously concerned because when I tilted the case, I could hear the nuts rolling around. I was fearful that something would short out if I turned it on. I contacted the seller and they quickly responded and were able to resolve the problem to my satisfaction.I was able to replace two 18650 batteries in an old Dremel Stylus and the spot welder did what was needed to weld in the new batteries. The Dremel Stylus works as well as new.

Easy to use, amazing on who quick and strong the welds are in seconds. when you do a set of batteries in a long line, it feels like eating corn, the whole ear. being able to move the tips in and out so simple to make just the right size welds. Looking foward to building of more batteries, I just wish we could get a reasonable priced 18650 batteries, so we could locally fill the need and demand for this move into the future. We would also like doing bigger sized batteries, Can't wait to take the next step. thanks Vevor... we feel you !!

I had to wait for my BMS's to show up so I have had this in the box until i needed it. I put mine on settings 2P/80 amps. This weld holds...I cannot remove nickel strip with my had and actually cut myself pretty good. I had to use pliers to remove the welded strip. So the weld is strong and not crap. I was a little scared at first to buy this device but I just had to jump in with both feet otherwise what are the other options? They only get more expensive and you just want this to do its job and do it right. This tool will work for you. I did not get a dud or one that did not work. No complaints here.

This works well, But, if you are looking to do a bunch, you need more power, you need to pay more. Makes small welds and needs to be hit several times. Hit too many time or too often, you reset the main breaker. If you are planning to do a bunch of welds, get a bigger machine. Works good for me, I don't do much.

I needed to set it on max to get the welds I was looking for.

Like it, useful for my DIY

I like the unit but it was obviously designed for 240 V A.C. and in the US the 120 V version comes with some caveates. For a start even a 20 Amp circuit make cause the breaker to trip if set to max power. I run it on a 30 Amp circuit in my workshop. Secondly the wand drops enough power that you will need to sharpen the probe tips or there will not be enough heat to make a good weld. After all that it works well for me and I like the T12 soldering iron it comes with.

showed up quick, even though it took a while for him to ship it but once he did it was quick and timely and it is what it is works great

Just completed 3000+ 18650 LiIon welding without problem.
