5. Setup

1. Initial Charging: Before first use, fully charge the spot welder using the provided Type-C charging cable. Connect the cable to the charging port on the device and a suitable USB power adapter (not included). The LCD screen will indicate charging status. Ensure the battery is fully charged for optimal performance.
2. Power On: Press and hold the power switch for 2-3 seconds to turn on the device. The LCD screen will illuminate.
3. Prepare Materials:
   • Ensure the nickel strips and battery terminals are clean. Use the included frosted paper (sandpaper) to lightly abrade surfaces if necessary to remove oxidation or debris.
   • Position the nickel strip securely on the battery terminal where the weld is to be made.

6. Operating Instructions

6.1. Understanding the LCD Display

The LCD screen provides critical information and allows for setting adjustments:

• Mode: Displays "Mode Auto" or "Mode Manual".
• Gear: Shows the current power level (0-99).
• Delay: Indicates the welding delay time.
• Preheat: Shows the preheating time.
• Battery Indicator: Displays current battery level.
• Temperature: Real-time temperature display.
• SET Button: Click to enter the settings menu for language, sleep time, screen brightness, etc.

6.2. Mode Selection and Gear Adjustment

The device offers two welding modes and 99 adjustable power gears.

1. Select Mode: Use the appropriate button (refer to device interface) to switch between "Mode Auto" and "Mode Manual".
2. Adjust Gear: Use the adjustment button (refer to device interface) to set the desired power level from 0 to 99.
   • A higher gear setting provides more output power, suitable for thicker nickel strips (0.1-0.25mm).
   • If the weld point is black, lower the gear. If the molten pool is too small, increase the gear.
   • Smoking during welding is a normal phenomenon.

6.3. Welding Process

1. Positioning: Hold the spot welder at a 45° to 60° angle relative to the welding surface. This angle facilitates easier and more effective welding.
2. Contact:
   • Automatic Mode: After setting the mode, simply make both welding pens fully contact the material. The spot welding will be automatically triggered after the set delay time.
   • Manual Mode: After setting the mode, first make both welding pens fully contact the material, and then press the power button to initiate the weld.
3. Ensure Proper Contact: It is crucial that both welding pens touch the material simultaneously to ensure a consistent and strong weld. Uneven contact can lead to poor weld quality.
4. Inspect Weld: After each weld, visually inspect the joint for firmness and appearance. Adjust gear settings as needed.
