    Is the machine still under warranty? If so, contact the supplier. If not, you could do is a visual internal inspection. Power off and disconnect the input power cable. Wait a few hours for any voltages held in charged capacitors to decay, then remove the casing. Look for any internal fuses, loose or badly-seated plugs and push-on tags, burnt components, loose or corroded connections, "dry" solder joints, and loose screws or bolts on the high-current wires and busbars.

    If it's really broken, there are 3rd-party companies that can repair inverters, but again, in the first instance, I'd recommend contacting the original supplier.

    I had trouble with mine last year.
    It was something similar with intermitant power.

    I found it was the power lead going into the welder had got a bit dodgy.
    I opened it up and shortened the power lead to get rid of the dodgy bit and it's been fine since.

    Step 1. Check the power socket it is being plugged in to

    Sounds like a broken mains lead if the light on the switch isn’t even coming on. Open the plug, unscrew the cord grip and pull on the live and neutral conductors. They shouldn’t stretch. If they do you have a broken one.
    Open the casing and do the same with the mains lead where it enters the set. Cables rarely break in the middle as they get bent at the same point all the time at the plug and the panel grommet.

    Hope you get it sorted easily.
