5. Operating Instructions
The AWithZ H5 offers both Automatic and Manual welding modes, along with 99 adjustable power levels for versatile use.
5.1 Mode Selection
The device supports dual pulse output with two modes: Automatic and Manual. You can select the mode that best suits your welding task via the display settings.
- Automatic Mode: For fast and simple welding, the device automatically triggers the weld when both tips make contact.
- Manual Mode: For controlled and independent welding, a dedicated button on the side of the device must be pressed to initiate the weld.

5.3 Welding Process
- Prepare the Surface: Ensure the nickel strip and battery terminals are clean and free of oxidation. Use the provided sandpaper if necessary.
- Position the Nickel Strip: Place the nickel strip firmly against the battery terminal.
- Position Welding Tips: Place both welding tips firmly on the nickel strip, ensuring good contact and even pressure.
- Initiate Weld:
- In Automatic Mode, the weld will trigger automatically after a set delay when both tips make contact.
- In Manual Mode, press the manual mode button on the side of the device to trigger the weld.
- Inspect Weld: After welding, gently test the strength of the weld. A strong weld should not easily peel off.
