I can’t say enough about how well this welder works. I had no problems setting it up and building up a 12cell battery for my portable vacuum. I tested a weld on an old cell and found the nickel strap fails before the weld. Good tool.

Just completed 3000+ 18650 LiIon welding without problem.

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.

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

Good

It would be great if it had more power, doesn't handle the heavier metals for stronger battery repair

Awesome, seller included VERY clear instructions, several types of sample strips and a whole huge roll of nickel plate strip. Some of the samples claimed pure nickel but last time I checked nickel was not magneticIts a little inconsistant with the wand but nothing devastating, and I wish the mounted arm was longer or adjustable. Can only weld 2 deep.

w orked good for a small battrey pack

I have only used the welder a few times. So far no problems. No tripped breakers, does a good job.
