Banggood

Minor assembly required with soldering iron. The Capacitor and Buzzer need to be soldered on, and leads have to be soldered as well. I put XT-60 on mine so I can power it with a large 5000mah 3S lipo, or use my Lipo charger in "power supply" mode. Very easy to do and board is marked for where the 2 items have to go. Assembled min in Excellent for spot-welding RC battery packs. Works on Nicad and NiMh batteries. Also works well for LiPo's. Make sure you lift the Lipo leads up, touch them together and then spot weld. Fold them back down when done

After I assembled the board with beeper, capacitor and the cables it was not working. There was no power at the welding tips. When checking the boards circuit I found this: MCU output -> drives a PNP transistor -> drives the gates of the N-ch FETs. I post a photo of the schematic: It cannot work. The diode is assembled in wrong direction (the PNP transistor will never switch on) and even if it is reversed it cannot work. The PNP transisitor is always on then because the voltage after the diode can never be higher than MCU power supply (5V) plus diode forward voltage. I removed the diode, PNP transistor and the rest and replaced it by a PC817 optocoupler, after that the spot welder works as intended. (The original circuit may work for battery voltages up to maybe 7-8V but not higher). Did the manufactiurer made this change recently? Other users will experience the same issue like me...

Esse foi rápido, chegou em 12 dias em casa (moro no BRASIL), o produto funciona sim porém a configuração não é igual do vídeo, quando vc energiza vc aperta o botão pra ligar e segura ele para a placa ficar dando o curto a cada 2 segundos, depois de um tempo a placa desliga sozinha, ai é só fazer o msm procedimento do botão novamente, não funciona em bateria lipo 3s 2200mAh nem em bateria de chumbo 7Ah, testei com a bateria do som automotivo de 90Ah, mas deve funcionar com bateria de carro, na foto usei um suporte no contato da bateria só para aumentar a área de energia, isso é importante também, é só, está aprovado, podem comprar sem medo.

доставка 3 недели, упаковка отличная, инструкции нет, но на страничке товара все описание есть, собрать легко, работает неплохо, все заявленные характеристики подтверждаю. За такую цену отличный выбор! Рекомендую!

Recommended: Comes with Zero instructions. Note: Looks professionally made but definitely DIY needed. Needs strong soldering iron for cable soldering. Cap and buzzer not soldered and the "simple" tips have to be prepared (see pic).

Taškinio suvirinimo aparatas tinkantis suvirinti plonas skardeles, pavyzdžiui akumuliatorių ar baterijų sujungimui. Maitinimas nuo 12V akumuliatoriaus. Yra keturi srovės stiprumo lygiai, perjungiami mygtuku plokštėje.

fazla deneme imkanım olmadı 3,4 defa denedim güzel iş görüyor ama amperin biraz fala olması gerekiyor 20 a bir aküye bağladım bir işe taramadı 40 50 a gerekli

needs a few mods to make better.. pen cables changed to 10awg .sharpen tips ..direct connect to battery..better lugs on ends of cable ..solder some copper down sides of board now works better than expected with small battery

Προϊόν καλής ποιότητας όπως περιγράφεται.Γρηγορη αποστολή!!! Πάρε ιδιοκατασκευές να μαθαίνεις και αγόραζε εργοστασιακές κατασκευές να κάνεις την δουλειά σου.......

works well, connected to large lead acid battery with 8 gauge wire and using banggood supplied handle
