    Re: Earth clamp died, modded a new one.

    Vice grips have been around for a long time. And one of the welders best friends. So many uses for
    everyday emergencies . Looking them up on the web. They were first invented in 1915 But the original plant was later
    moved to China. I always thought Irwin was the original But they are only a branch of B&D and dewalt.
    I Have just used the vice grips to clamp the bare end of the ground clamp to the table when the clamp fails.
    They also work well for clamping the cable to the battery terminal when the terminal gets loose

    I have a Tweco brass clamp that I got on ebay several years ago and have yet to use it on any of my machines.

    Me too. I tossed the steel one on my HH 135 and grabbed a HF brass ground clamp. My only gripe is that itís grip range is a bit small.

    Chill.

    You need to get a grip on your gripe range.

    When the cable between the jaws destroyed itself I braided a new one from some old jumper cables, it's heavier that the original cable & works well, the jaws are bolt in brass/bronze.

    These are my preferred clamps these days. The old steel/copper ones give up after a while, the braid fails and melts everything else. This one looks OK but isn't repairable, I just replaced it today.


    The brass ones work well with pulse mig and I've been rattling through some structural steel for a building recently, so good torture test.

    Re: Earth clamp died, modded a new one.

    The best ground clamps Ive ever used are the Lenco big brass or copper clamp types, Tweco makes one as well but its not quite as heavy as the Lenco clamp. Thats me though I push things pretty hard at work and pretty much evrything
    Ive got is as heavy duty as I can get. Ive had this one Im usin now about 5 years or so

    I tried to load a picture of it here but it keeps comin up as an invalid file

    Earth clamp died, modded a new one.

    Dammit, I tried to do this again and the same thing comes up ... invalid file. Anyway Im sure most of you have seen them .. big brass c clamp type thing. They are very durable.

    I like the idea of the wide jaw opening and quick adjustment.
    I was going to do that with an old visegrip c clamp I have
    but I was concerned about the jaw pivot heating up
    because of the small contact area of the pivot. Not sure
    if that would really be an issue or not.

    Those tweco brass clamps are sweet. The idea of keeping the spring at the back (and therefore furthest away from heat) is excellent.

    They can be a bit stiffer to squeez too. Oh that didnít come out right.

    The one I rigged up never had any heating problems with 200 amps. just clean a spot and make sure it's tight. Used it on a Dialarc 250 for many years.

    I use a 5" C clamp. Drill a hole in the clamp and attach your ground with a copper lug soldered to your cable lead. Never gets hot and never slips off. Also works good for orientating small parts for welding.

    This is the clamp that came with my Fronius.




    I haven't used it yet but the weight and quality is incredible. Without a doubt the nicest one I've seen.

    Fronius makes great stuff. No confusing it with Harbor Freight. I have a Miller Maxstar 140 STR from about 2003 I think. It was made by Fronius for Miller. Itís an incredible little welder

    Re: Earth clamp died, modded a new one.

    Has anyone mentioned the magnetic weld ground?
    I keep one next to the welder in case there is no easy spot to get the clamp on.

    I have about 6 feet of cable on mine, with a crimp on end holding the wires from frazzling,,



    Shouldn't this guy have his tungsten sticking out a little further??

    I use my switchable magnetic ground about 90 percent of the time.

    Here's an old abused one I have kicking around.....




    Just needs a clean up with an angle grinder and it's good to go.

    Either that or I have 1.75 pounds of scrap copper or bronze LOL
