Was great for few test welds and then began to sparks fly from PCB, one small transistor melted and few mosfets went hot and bit smoke. I read one review where was similar case like i have, not sure did we just get bad monday items or what. Small minus, does not contain any instructions, for example what led colors means would be great.

it works well, using 4S lipo battery. when using first and second level of power, device and battery do not get too much hot, so you could make many spot weldings.

The spot welder works like a charm. Before using, make sure to solder the capacitor to the input of the device. I spot welded a 1.5 mm thick nickel strip with the LVL 3 power (Blue colour). For the best result use a big 4s lipo Battery. I used a 5000 mAh 60C lipo. You need at lease 150A discharge current for the device to work properly (You can calculate the max discharge current by multiplying the capacity with the C rating. For example, if the Lipo has 2000mAh and 100C the calculation should look

This board is very nice, and works quite well. So far very happy with this board. The mounting holes are very small. The positive is a 2mm hole, and the negative is 3mm. I made a brass extender for the positive on my Mini Lathe. Used a 3mm brass riser and turned down the 3mm screw end to 2mm to fit the hole on the board. I then soldered this to the board, so I had a 3mm location to mount the positive connection. I had some welding tips from another board that failed, So I used those. Had to use

Sehr gute und günstige Lösung, durch die Möglichkeit die Schweißzeit einzustellen lässt sich die Leistung gut regulieren. Der strom lässt sich über den Ladezustand der Akkus und der Kapazität/c raten beeinflussen. Was am Anfang etwas probieren erfordert. Am besten erstmal nur die Nikelstreifen verschweißen da bei zu höhen Einstellungen die zu verscheschweißende Zelle beschädigt werden kann.

Seems to do what I need done using the Red and Green settings. Purple BLOWS holes in 18650 cells. LOL Bet folks would be willing to pay a extra dollar for documented instructions ? I located the Cap on the underside.

not to happy with item no one knows where to solder capacitor! finaley figured it out , worked great firs time then burned out 2 x fets on second try!

thank you

Works good. Included Instructions would be great.

gute Sxchweißnadeln
