    The evaporator has a multicircuit feed. If you looked it has a capillary tube feeding each of the circuits. Most likely wax from the oil has plugged off one of the tubes. The typical fix for that is...

    I don't know why it's running reverse.
    But I've had two window units that stopped working, and I replaced with a new unit. I went to scrap the old units, and found both had extreme dirt on the...

    If there is a power factor capacitor bank that you can purchase for your Dynasty 300, that will make a difference in peak amperage used during welding.

    These varistors should have been wired to ground. Get two news ones, of the same value, and wire them to ground not differentially across the 240 power. If they are for surge arresting you want the...

    I can't help with the move. The lathe belt, use one of those link belt types that enable you to thread it back around the spindle V pulley and motor. That way you won't have to remove the spindle...

    The second photo, as sketched, is showing sine (opp/hyp), not tangent (opp/adj), slight different arcsine angle is 9.449 degrees. Probably don't matter for this oil groove application.

    I'm just guessing here but experience in closed loop systems say's either your shaft encoder has a problem, but this may be as simple as a loose set screw, or the optical grating has come loose from...

    Here you go;
    Feeder and Secondary Tap Rules

    What is that rule? All I know is the ampacity of the wire must stay to the size required to trip a breaker, so no 12AWG taps on 6AWG wire without a fuse stuck inline (and I'm not sure that's code,...

    I'm north of Cedar Rapids 8 miles, I'd help you out if I was closer. My sister lived in West Des Moines, just north of the Ballroom, back in 1992.

    You can parallel many of the 20amp 240volt outlets off one breaker. Looks like that panel has no spare connections available for another 20amp 240V dual pole breaker. I would find the lowest cost...

    Is this 50amp circuit connected to wall outlets? Or is this just a power feed from a main breaker to the shop and connected to nothing right now?

    Jon, do you have a schematic for this power feed? Can you share it?
    I installed this years ago, and the manual never had a schematic.

    As JST commented, search for "carrier frequency" in your VFD manual, this is changeable.
    One of my VFDs is settable from 750Hz to 16KHz. The issue is if you use a very long wire from the VFD to the...
