✓60-Second Fast Startup: The Awgem SF2K accepts 100–240 V AC input. Connect the included AC power cord to the welder and plug it into a wall outlet, and the supercapacitor reaches welding-ready status in about 60 seconds. When the display shows "OK," select the required settings and begin welding
✓3 Welding Modes: Choose from Auto, Manual, and Foot Pedal modes to suit different workflows and welding tasks. In Auto Mode, welding is triggered when both welding tips contact the material, making it suitable for repetitive welding tasks. In Manual Mode, press the button on the welding pen to trigger each weld individually. Foot Pedal Mode keeps both hands free to position the battery and nickel strip accurately before each weld – making operation easier for beginners
✓10.5 kW Supercapacitor Output: The built-in supercapacitor delivers up to 10.5 kW of welding power, a peak current of 1,750 A, and a 6 V output. Dual-pulse technology delivers two controlled energy pulses to support stable, repeatable welds across different materials and thicknesses. If low voltage or excessive temperature is detected, the machine sounds an alert and automatically stops the welding output to support safer operation. Note:This corded supercapacitor spot welder must remain connected to a wall outlet during operation
✓Precise 1–99 Power Adjustment: Adjust the welding power from 1 to 99 using the rotary knob. The LCD shows the operating mode, preheat time (0-0.5ms), pause interval (1-20ms), power level (1-99), trigger time (0.5-5s), cont welding (1 or 2 welds), and internal temperature, making it easy to review the settings before welding and adjust them after a test weld
✓Wide Application Range: The SF2K welds up to 0.4 mm nickel-plated steel, 0.25 mm pure nickel, 0.4 mm steel, and 0.4 mm iron. It is designed building and repairing battery packs made with 14500/18650/21700 cylindrical cells, as well as LiFePO4 battery packs. It is also suitable for power tool battery packs, battery pack repair, and DIY battery projects
✓Complete Spot Welding Kit: The package includes one SF2K spot welder, one pair of welding pens, one foot pedal, one AC power cord, two pairs of welding tips (2 Pre-installed), one 2 m (6.6 ft) roll of nickel-plated strip, sandpaper, battery holders, one cell bracket and a user manual. The main accessories required for spot welding are included, so you can begin working after setup. suitable for battery pack builders, repair technicians, and DIY battery enthusiasts
