    Default Proper Shutdown Procedure for Syncrowave and MM.

    I don't ever leave the gas valves open when I am done welding for the day. I shut the cylinder valves and then bleed the gas off. On my Syncrowave 200, it's just a matter of turning the machine on and depressing the foot pedal until the small amount of gas left in the system bleeds down.

    The Millermatic 252 is another issue, however. When you close the valve on that one, if you bleed the meter down, you will feed a couple of feet of wire. You could run the wire speed control down I guess, but you would still get some wire.

    I guess I could open the cover and loosen the rollers and wind the wire back in. I don't like to waste the wire if I can avoid it and I don't leave the gas on. I was wondering what others do. What procedure is best?

    Why do you need to bleed them down? They will probably leak down by themselves. Besides if they leak down too fast you have a problem. A good morning is when I come in and find the pressures exactly the same as I left the day before.

    My take is the more you cycle the gauges, hoses, and valves, the faster they wear out.

    Course I could be all wrong. Anyone?

    Since I work alone all of the time, I'm in the habit of shutting every thing off when I leave the shop. I know a machinist friend who also welds and he just closes the cylinder and leaves the line unbled. He's been doing that for years but I haven't done that yet. He says that it hasn't hurt anything in all of the time that he's been doing it that way.

    The manual is silent on this issue. I'm open to suggestions however.

    Me too, and unplug the welder or throw the breaker.

    What is bleeding the argon supposed to accomplish or prevent?

    I have a Syncrowave 350 that is mobile that we do bleed the gas before transporting the unit. I have had issues with gauge needles breaking and since we started to bleed off the gauges before transporting not another issue since.
