Overview
Portable Battery Spot Welder 1200 A with Display and 5000 mAh Power Bank, 0.1–0.4 mm, Double Pulse, Black, for 18650 and 21700 Cells

The portable spot welder with a maximum welding current of 1200 A is designed for joining nickel strips and sheets during the production and repair of battery packs. Thanks to the double pulse technology, the first pulse removes oxides and reduces spatter, while the second pulse provides stable energy for a reliable weld. The device can handle materials with a thickness of 0.1–0.4 mm, such as pure nickel, nickel-plated steel, iron or stainless steel. The built-in battery of 5000 mAh allows operation without connection to the mains and also serves as a power bank for charging a phone or tablet. All parameters are set using a rotary knob and buttons and are clearly displayed on a 2.4-inch colour TFT display.

  • Maximum welding current of 1200 A with 4 preset combined power levels
  • Double pulse with adjustable preheating of 1–10 ms, main pulse of 1–99 ms and interval between pulses of 1–10 ms
  • Continuous spot welding mode of 1–9 spots and over 10,000 combinations of settings for fine tuning
  • Maximum thickness according to material: stainless steel 0.4 mm, nickel-plated steel 0.3 mm, iron 0.3 mm, pure nickel 0.2 mm, nickel-plated copper 0.1 mm, brass 0.1 mm
  • 2.4-inch colour TFT display shows battery voltage, temperature, number of welds, output voltage and current, the image can be rotated 180°
  • Control via rotary knob and two buttons
  • Two high-current battery cells with a total capacity of 5000 mAh, approximately up to 1,500 spot welds according to the manufacturer's laboratory measurements
  • Charging 5V/2.1A via USB-C, USB-A output 5V/2.1A for charging a phone or tablet
  • Adjustable automatic shut-off in the range of 0–99 minutes
  • Removable copper welding tips and thick copper supply cables with low resistance
  • Protection against overcharging, deep discharge, short circuit, high and low temperature, impact protection and voltage stabilisation
  • Folding stand, non-slip silicone finish, side status backlighting and width of approximately 13.3 cm
  • Colour: black with blue elements
  • Package contents: spot welder, 2× welding pen, 2× spare welding tip, nickel strip, USB-C cable, user manual

The welder is suitable for assembling packs from 18650 and 21700 cells, repairing battery-powered tools, building batteries for electric bikes and replacing cells in mobile phones. Fine adjustment of pulse timing allows adapting the power to the specific material and thickness of the strip. Compact dimensions and its own battery facilitate work in the workshop, in the field, and during service on the go. The power bank function extends the use of the device beyond welding. For a quality weld, it is important to use both pens simultaneously, maintain the appropriate distance between tips, and weld clean and straight materials free of corrosion.
