Portable, Powerful, Reliable: Your SpotWelding Solution Introducing VEVOR 788H battery pulse spotwelder battery charger - your ultimate solution for enhancedwelding efficiency. With 2.8KW pulse output power and 300g-750gadjustable welding needle pressure, it achieves superior spotwelding results for battery pack, pure nickel, and platednickel. Our pulse spot welder combines powerfuloutput energy with welding precision. 2.8KW pulse output powerensures efficient completion of welding tasks. Additionally, itcomes with 300g - 750g adjustable welding needle pressure fordifferent welding conditions. This battery welding machine offers 2welding modes: fixed head welding mode and pedal mode. In fixedhead mode, efficient welding can be easily achieved; while in pedalmode, precise welding can be achieved to meet the requirements ofprecision spot welding. Equipped with an intelligent LED paneldisplay, this lithium battery spot welder can monitor welding powerand actual welding current in real-time. The user-friendlyinterface allows users to monitor the welding status at any time,effortlessly mastering the welding process. In addition to the spot welding function,this portable battery pulse spot welder also comes with anadditional testing function, facilitating battery charging andtesting.
