Features: Eliminate bulky and cumbersome traditional spot welders with our compact spot welder control board, a much-needed tool in the 18650 battery pack assembly process. Rather than relying on a sizeable transformer structure common in ordinary spot welders, this model features a 10000mah power capacity derived from three series of iron-lithium batteries.

Say goodbye to inaccuracy, as our spot welder eradicates the issue of inaccurate current control, which often results in blackened or weak solder joints. The product supports direct spot welding of nickel tape below 0.25mm, promising sturdy adhesion suitable for non-industrial buyers.

This compact spot welder is especially perfect for the battery assembly spot welding of 18650, 26650, 32650 batteries. It supports 0.1-0.25mm nickel plating or 0.1-0.15mm thick pure nickel sheet, guaranteeing strong adhesion.

At this point, we are offering the product without a shell. However, we are working (in the next step) to introduce an option with a shell to enhance user convenience.

Precautions:

  1. Altering the power supply voltage and power of the product is strictly prohibited.
  2. Unauthorized connection of wires is highly discouraged.
  3. Only our specific chargers should be used for re-charging.

Instructions for use:

  1. To prevent short circuits, a heat shrink film will be placed on the battery, which is already charged.
  2. Upon receiving, carefully remove the first layer of the heat shrinkable film, making sure not to short the electrode.
  3. Insert the battery screw into the board’s hole and correctly fasten the nut.
  4. Both electrodes should be in contact with the nickel strip and battery surface synchronously.
  5. By pressing the switch, weld through direct discharging.

Keep in mind:

  1. Avoid holding down the switch for a prolonged duration.
  2. Firm pressure is needed when spot welding to prevent poor contact.
  3. If discharge is insufficient, ensure to recharge using our specialized 10.8v charger and refrain from causing a short-circuit to the battery.

Package Includes: 1 x 7.4V Spot Welder
1 x Charger

Note: As of May 7, 2020, we have upgraded to the 2020 version of the intelligent automatic spot welding machine for an improved experience.
