  • 400amp Quick Connector Lube?

    Sometimes.. I find my 400amp quick connectors bind shut.. I need to pull back the rubber franger things and put some vice grips on them to unhook them..

    They get hooked/unhooked a lot.. I have a TIG HF Unit, a 12VS Suitcase Wirefeeder and my Stick holder.. they all have quick connectors on them.. at least 1-2 times a day I'm changing betweeen MIG, TIG and stick.. its winter here, so sometimes my leads get a bit muddy as I drag them out.. I'm sure its the dirt thats probably causing them to bind.. I clean them up with a rag before I hook them up, but they're still binding occasionally..

    I feel like I should whack some kinda lube on them.. but I'm not sure what.. any recommendations?
    Cheers,

    Dunc.

    Well, if you think it will help try petroleum jelly(vaseline).Its used on electrical connections to keep away corosion.

      Check your local electrical supply houses for silicone grease. It's used in high voltage connections. You'll still need to keep the dirt off the connections however.

        Dielectric grease is what you need, however any type of "lubricant" is going to make the connections more succeptable to dirt buildup.

        Sounds like you're going to have to make a more concerted effort to keep the cable ends clean.

          You DON'T want to grease those lugs with any thing, best just to buy some good quality lugs in the first place, instead of the more common chinese junk.

            I haven't had any troubles ever with Tweco and Lenco connectors. But I had a set of cheapies that got fried in the first week.

            I just keep them clean.

              That's what silicone grease is.

                You make a good point.. keeping them cleaner it is then..

                Thanks everyone.

                  Of all the DINSE connectors on my various cables, only the E-Bay vendor/el cheapo variety bound up.. I used some emery cloth on the few that I have while sitting and watching TV. Now they work ok without lube.

                      If you keep them nice and clean (emory will keep the male end bright, one of those wire brushes made to clean battery terminals/ends will keep the female end bright) then you can quickly adjust the drag on the connectors, use a hammer and close down the male end if it's too snug, drive a spacing tool (or small wedge or even a screwdriver) into the slot on the male end until the fit is nice and snug, but not too tight.
                      If they feel too hot under heavy use, it's time to clean the connecting surfaces, or tighten up the fit, or cut off a foot of lead and make a new lead to connecter connection with bright/clean lead.
