    Default Dual Laser 110v plug melting

    I have a Gweike laser and the power plug housing has literally melted twice in the last week (see picture). Any ideas?

    if the wires are good you need to get stronger plug..
    that happens when the machine consume a current higher than what the plug can carry ..
    more current more heat

    do you know what power the Laser cutter takes ?
    does it have any mains outlets to power external devices like a water chiller and or extractor fan ??
    its possible the combination of these is overloading the 10A mains inlet

    PS

    if your laser cutter / engraver has outlets like this :

    with a 110V mains supply the total load must be limited to 1100W

    if the laser cutter takes 300W , the total power that can be taken from the mains outlets
    will be 800W (you may have to reduce this if the chiller and blower take a large start up current)

    I will 3rd what the others have said. Don't power anything using the power outlets on the back of the machine itself.
