【250 Gears Adjustable】 3000F Capacitor Battery Spot Welder with LCD Display can automatically feelthe welding needle contact nickel belt, automatic output pulse, can also be connected to the foot switch.

【Built-in power balancing circuit】Ensure that the voltage of the two batteries is equal to protect the capacitor use.

【Intelligentfan temperature control strategy】When the voltage isfull, the fan stops rotating, prolongthe life ofthe bearing

【Capacitorcan】Provide extremely fast chargingand discharging ability. Aluminum using inert metal- brass gasket, avoid electrochemical corrosion,good to ensure the use of stability. Screen out lessthan 0.6mR internalresistance, high standard to ensure consistent and stable quality.

【250 speed hyperfine adjustment】Fast/slow knob can quickly adjust the gearwithout of sync precision.
