Thread: Grounding the work table

  1. Default grounding the work table

    While searching for this topic I found a discussion on the MillerWeld website that covers the same issues. I think it is worthwhile to read the replies there , particularly on page two.

    http://www.millerwelds.com/resources...lease%29/page2

    The bottom line (in my interp) is that grounding various pieces of equipment or the table to separate ground rods won't work since they are all at slightly different voltage potentials and as such will generate various 'swirling' currents. If you insist on grounding multiple items or building Faraday cages, they must all go back to the neutral bar of the building's electrical service.

    You really must check out this video. The work clamp is a wire to a stake in the ground. They weld with only one lead. The comments are truly hilarious.




    Check out how he dunks it in the dog water dish, and drops it in his pocket.

    i hope he trains that dog to be a seeing eye dog, because he will be blind soon. but then again the dog will be blind too, then he will be dinner.

    I can't see the video- is that the one with the guy leaning the wire against a hot lead? I couldn't figure out why he stopped every few seconds, until I realized he had to stop the arc to open his eyes to see which direction his weld was taking him. At one level I admire the "improvise / adapt / overcome" ethic but the rest of me is cringing on his behalf.

    It is one of the funniest videos i have seen on the internet. The comments left largely by real life weldors are the funniest part.

    Does Everlast sell these? They might be missing out on a niche market...

    I think it may be that video. In the begining it looks like he just sets the wire on the hot one. I assumed he was closing his eyes for the actual weld time also and hope that is true but who knows.

    Old video. Forgot about this one.

    I would like to see him barefoot doing this, that is an accident waiting to happen.

    I heard Jody C will be testing one next week (kidding Jody).

    Talking about old videos, anyone have a link to the "worlds best stick welder". Have not seen it in years. Guy talks, looking at a camera and welds large pipe over and over, fast as he can move.

    That was a hoot and some of the scariest disregard for electrical safety that I've seen in a long time. There was a time long, long ago and hopefully long forgotten when similar products were actually sold right here in the US of A. As a youngster I developed an early interest in all things electrical and mechanical. As soon as I could save up $15 I ordered a welder out of the back pages of Popular Mechanics magazine. Ready to go right out of the box with hood and starter supplies. While I was able to operate the carbon arc torch accessory I never was able to get it to strike a decent arc. Mine was the Midway Electric Arc Welder in the picture below taken from a 1966 Popular Mechanics review of several versions of this suicide box. They actually gave them a decent review. Fortunately I've alway had a healthy respect for electricity so I didn't become a victim before retiring the unit to my parent's garage where I guess they eventually tossed it out. Just 120 VAC thru some coils of nichrome wire to limit the current. They were all a subject of a product safety recall in 1976 after a zillion of them were sold. I've seen write ups of folks doing similar welding using a 220 V electric water heater as the current limiter. Thank you very much but I'll stick with my 200 DX.

    When the table is grounded into your electrical wiring, you can damage your equipment in the shop if you forget to attach the ground clamp to the table. I had a metal work light during on my weld table that had a chassis ground, and I forgot the ground clamp and it toasted the light and some cfl bulbs that were on the same circuit. Regular equipment just isn't built to handle the hf start, or low voltage amperage of a welders work circuit.

    LOL... $14.95 = two or three tanks of gas in 1966.

    That still works... you can buy a cheap busted welder from harbor freight for 2-3 tanks of gas ($120). And... they are just about as reliable and safe as these. =)

    Yep, those old welders were pretty scary.
