    Default I have an Miller Syncrowave 300 Ac/Dc TIG whats not vill work Correct!!

    I have a Miller Syncrowave 300 Ac/Dc Tig not work as it should!
    stick works!
    But not TIG with switch In remote mode! no power then!
    but if change the contactor they will get full power ut then as soon as the stick makes contact with the -ground!!

    Yes!!! I saw a power cord that has connected to it was incorrectly fitted the phase set at zero! so maybe something happened!!

    The relay cr1 its work then i put thw switch to contacor mode,but the relay are not work with the pedal or the button on the handle!!!

    Anybody that have any idea what they might be doing wrong?

    I would test the remote - first test replace with a known working one.

    If that is not an option, you can short the remote contact pins. See the service manual to get the pin numbers.

    Leave the power control on 'local'

    You lost me (for sure) when you said the power cord was incorrectly installed and phase was set to zero.

    Is English a second language?

    Check pins A and B on the remote for switch closing. check C D and E for adjustable resister. Short pins A to B is remote socket. see if relay CR2 closes.
    If CR2 closes but welder does not work. look real close at the relay and see if one of the wires inside is broken. If the current control is set in panel and set to max you will have max output when ever contactor switch is closed.
    Made sure the foot control and panel switches are all working and the cr2 relay.
    Then we will look deeper in the welder. Post back with the serial number so I came use the correct diagram to help you with.

    You still haven't stated if you have tried to trigger the machine jumping across A and B with the remote unplugged? Have you tried that in tig mode to see if the contactor closes. that's the first test you need to do.
