1Set DC 6V-24V Handheld Spot Welding Assembly Kit Mini 6 MOS Control Circuit Board Welder Pen Nickel Sheets for RC DIY M

Specification Workding voltage 6 24V suggest to use with 6 18V Working current 90 200A the best working current should be 150ARecommended battery 36 60AH car start battery 20AH motorcycle battery 2pcs or 3pcs in parallel 2S 5S 4000mah Lithium ion battery with discharge above 30CFeatures The board uses 6 MOS tubes with extremely low internal resistance single 300A total 6MOS which is 1800A which greatly improves the stability of the circuit Designed a voltage stabilizing circuit so that the MOS drive voltage is no longer dependent on the battery and is more stable and reliable so that the board can support 6 24V wide voltage use The new circuit layout greatly reduces the internal resistance generates less heat The external interface of LED and button has been added to facilitate the installation of the board in the box Optimized the program to make the operation more convenient and freePackage included 1set x Spot Welding Assembly Kit1set x Spot Welding Assembly Kit w 5m nickle sheets
