5. Setup
5.1 Initial Charging
Before first use, fully charge the H5 spot welder using the provided USB Type-C cable and a compatible power adapter (not included). The display will indicate charging status. Ensure the device is cool before charging.
This image displays battery charge level indicators and a crucial precaution: the spot welder must be cooled down before charging to prevent damage. It shows a USB-C cable connected for charging.
5.2 Adjusting/Replacing Welding Tips
The welding tips can be adjusted for wide or narrow spacing, or replaced if worn. Follow these steps:
- Loosen the fixing screw counterclockwise.
- Carefully pull out the spot welding tips using a tool if necessary.
- Insert new tips or adjust the existing ones to the desired spacing (wide or narrow).
- Tighten the fixing screw clockwise to secure the tips.
A step-by-step guide demonstrates how to loosen the screw, pull out the old welding tips, adjust the welding spacing (wide or narrow), and tighten the screw for the replaceable spot welding needles on the H5 unit.
5.3 Language Selection
Upon first power-on or if needed, you can select your preferred language from the device's menu. Use the Adjustment Key to navigate and the ON/OFF/Option Toggle Key to confirm.

6. Operating Instructions
6.1 Power On/Off
- To power on, press and hold the ON/OFF/Option Toggle Key.
- To power off, press and hold the ON/OFF/Option Toggle Key again. The device may also have an automatic power-off setting configurable in the menu.
6.2 Navigating the Display and Settings
The OLED display provides access to various settings. Use the Adjustment Key to scroll through options and the ON/OFF/Option Toggle Key to select or confirm. Available settings include:
- Temperature Display: Shows the internal temperature of the device.
- Mode Selection: Choose between Automatic and Manual welding modes.
- Preheat Time: Adjust the preheating duration.
- Trigger Time: Set the welding pulse duration (0.5ms to 5ms).
- Power Level (Gear): Select from 99 adjustable power levels.
- Language: Change the display language.
- Sound: Toggle sound alerts on or off.
- Display Brightness: Adjust screen brightness.
- Automatic Power Off: Set the inactivity time before the device powers off.
6.3 Welding Modes
The H5 offers two welding modes:
- Automatic Mode: For fast and simple welding. The device detects contact with both probes and automatically triggers the weld after a pre-set delay.
- Manual Mode: Provides controlled and independent welding. The weld is triggered by pressing the Trigger Button after positioning the welding tips.
This visual compares the two welding modes: Automatic for fast and simple welding, and Manual mode, which uses a trigger key for controlled and independent welding, suitable for battery repairs and rebuilds.
6.4 Welding Process
- Prepare the surfaces to be welded. Ensure they are clean and free of oxidation. Use the included sandpaper if necessary.
- Select the appropriate welding mode (Automatic or Manual) and adjust the power level (Gear), preheat time, and trigger time based on the material thickness and type. Start with lower settings and increase gradually if needed.
- Position the welding tips firmly and squarely on the nickel strip and battery terminal. Apply consistent pressure.
- In Automatic mode, hold the tips in place until the weld triggers. In Manual mode, press the Trigger Button once the tips are firmly positioned.
- After each weld, inspect the joint for strength and consistency. Adjust settings as needed.
