Works as advertised, spot weld works, current limited battery charging works as well, haven't used the usb charging port, don't really see the need for it in this type of appliance
Good machine for the price.Works very well on nickel plated strips 50-60 setting.Pure nickel strips around 90 setting, getting close to max O/P of 99.15A plug with regular earth pin, been using a 10A pwr point and hasn't tripped..still testing.JB
the only complaint is the soldering iron only lasted 5 min but that is not what i bought it for the spot welder allowed me to put together my lio4 battery with 400 cells so many many spot welds and is still working
