5.3 Adjusting Welding Pin Spacing
The welding pin spacing can be adjusted between 0.5mm and 3mm to suit different welding needs. This is crucial for achieving optimal weld quality.
- Loosen the fixing screws on both sides of the welding pins using a 3mm outer diameter cross screwdriver.
- Carefully move the welding pins up or down to achieve the desired spacing.
- Tighten the fixing screws firmly to secure the pins in place.

5.4 Replacing Welding Pins
The welding pins are replaceable. If they become worn or damaged, follow these steps:
- Loosen the fixing screws on both sides of the welding pins.
- Remove the old soldering pin by pulling it along its direction.
- Insert a new soldering pin.
- Tighten the fixing screws to secure the new pin.

6. Operating Instructions
6.1 Selecting Welding Mode (Manual/Automatic)
The device supports both manual and automatic welding modes. Short press the mode switch button (usually labeled "Manual" and "Auto" on the device) to toggle between these modes.
- Automatic Mode: The device will automatically detect contact with the welding material and initiate a weld. This mode is intelligent and efficient for repetitive tasks.
- Manual Mode: You control when the weld occurs by pressing the manual welding key. This mode offers precise control for specific applications.

6.2 Adjusting Welding Power Levels
The spot welder features adjustable output power levels (11 gears for SH1, 90 gears for SH2). Short press the power level adjustment button (often the same as the ON/OFF button) to cycle through the available power levels. Adjust the power according to the thickness and type of material you are welding.

6.3 Performing a Spot Weld
- Ensure the welding pins are clean and properly spaced for your material.
- Place the nickel strip or other weldable material firmly against the battery terminal or surface to be welded.
- Position the welding pins onto the material, ensuring good contact.
- If in Automatic Mode, the weld will occur automatically after a brief delay. If in Manual Mode, press the manual welding key to initiate the weld.
- After welding, carefully remove the device. The welded joint should be firm and secure.
The device is capable of welding various materials up to 0.25mm thickness:
- Nickel plating: 0.25mm (MAX)
- Steel sheet: 0.2mm (MAX)
- Iron sheet: 0.2mm (MAX)
- Pure nickel sheet: 0.15mm (MAX)
