Instructions: Charge the product first. The default low voltage storage and must be fully charged for welding test Long press the "power on" button for 3 seconds, release the button when you hear a sound start. Press and hold the "SHUT-DOWN" button for 3 seconds, then release the button when you hear a sound shut down. Short press the "Gear Switch" button, the buzzer will ring and switch between gears. "Auto Shutdown" will start an automatic shutdown if you do not perform any welding work within 10 minutes. USB Charging Function: Automatically turns on the USB output when the USB is inserted. When the load current reaches less than 50 mAh, the USB will automatically turn off the output. Short press the button will trigger the USB output. Welding Operation: After inserting the welding pen, first welding with gear 1. After inserting the welding pen, the host recognizes and starts welding after 0.5 seconds, adjust the gear as needed, soldering using an external USB charging cable. "Error Warning" buzzer keeps ringing after power on, indicating that the host is damaged and cannot be welded
