What cells can the PN360 weld?

It is built for 18650 and 21700 cells and phone battery cells, plus small metal components. The 4.2V output ceiling means it is not intended for thick sheet metal.

Through a USB-C input port at a maximum of 5V/2.1A. That is a slow charge rate for a 4000mAh cell, so plan on a long top-up between sessions.

What is double-pulse welding?

It fires a first pulse to clean and prep the spot, then a second to fuse the strip. The guided mode handles the timing so results are more repeatable than a single manual pulse.

Can it store my weld settings?

Yes. Preset memory gears let you save and recall settings for different strip and cell combinations instead of dialing them in each time.

Is it a replacement for a mains spot welder?

No. It is a portable tool for battery tabs and small parts; heavier metal and high-volume production still call for a mains-powered welder.

What comes in the box?

The unit itself with its built-in 4000mAh battery. Check the listing for included weld pens, strips or cables, since those are not stated.

Our take on the PN360 Portable Spot Welder with TFT Color Screen

The Lumeo PN360 is a battery-powered spot welder for building and repairing battery packs, aimed at 18650 and 21700 cells and phone cells. It runs on an internal 4000mAh cell rated at 70C discharge and delivers up to 650A output at 4.2V, using guided double-pulse welding. A TFT color screen and preset memory gears set it apart from bare dial-and-trigger welders, which usually lack a display or stored settings. It suits DIY pack builders and repair techs who want a self-contained unit; it is not a substitute for a mains-powered welder on thick metal or heavy production work.
