Mini spot welder for making battery pack of 18659 cells. Teardown: https://youtu.be/WjJXhLWO9pM This spot welder comes with a 4300 mAh li-poly battery, which can deliver current up to 600 A. It has a type-c USB port for charging. This spot works in two modes: Automatic and timing mode. In automatic mode, this welder turns on after 1 sec when touching the nickel strip and in timing mode, it turns automatically on every 1.5 seconds for 1 sec. Timing mode is useful for continuous welding and automatic mode is suitable for a few welds. We test this welder over a large number of Li-ion and AA cells. The welding quality is very good and strong and stable. We will recommend this product. his spot welder has two Lithium-polymer batteries of 2150 mAh each, which can deliver up to 600 Amperes of current. There is a small microcontroller inside this unit that drives the combination of 4 MOSFET to deliver the current to the welding probes. And also, there is a tiny IC for charging batteries inside this Mini module. Working on this Mini spot battery is very simple. Current from the batteries is modulated by MOSFET with the help of a microcontroller. This high current is then fed to the welding Probes, which has very small resistance as compared to nickel. When heavy current passes through these probes to the Nickel, Nickel melts up and because of the small pressure from the probe tip, the nickel beneath the probes melts and penetrate inside the bottom metal. This makes the welding. Welding strength depends upon how far the nickel is penetrated inside the material which depends upon the welding current, nickel ate thickness and bottom metal type.

Q: where is software

Kérdezte bhubesh25 tovább 2019-12-17 01:49:04

Doctore Here you go: witrn.com\witrn\upd\upd005_software.rar (replace backward slash with forward slash). Shall the URL become obsolete or 404, just ask and I can upload my copy to google drive. I really don't understand why on witrn.com - manufacturers website, there's no browsing of the website, you can't find the software, they really have to fix it. Same with sellers, they show screenshots of the upgrade software yet don't give you the link. EVENE THERE they are unable to answer the question. I never struggled soo much to obtain the software...
