Reply:Electricity naturally wants to return to the source.  If the ground thing was a problem then anyone who ever sat a welder on a metal table and welded would have burned something up because the case on the welder is directly bonded to the ground from the power source.The source of the power is the transformer. In commercial building we bond every transformer at the case and common (white neutral) to building steel. Sometimes 20 or 30 of them and we never have a problem with it because current always looks for the place it originated. Otherwise not one single circuit would have proper voltage

Reply:Mondo, apparently you didn't see the table builders post in response to the convenience electrical configuretion. The table is completely insolated from that electrical supply. therefore, 0 risk of fried stuff.There are no problems. There are only solutions. It's your duty to determine the right one.Hobart Handler 210Airco 225 Amp MSM Stinger
Reply:Originally Posted by DukerI hadn't thought about current coming from the welder but was more concerned about a short in the electrical making the whole table hot so the electrical boxes are ABS and mounted with nylon bolts & nuts so there is no metal contact with the table.
Reply:Originally Posted by DukerLOL, what can I say I am just a weekend hack. As, for who made the table, you can check out the build thread in my signature and you can decide.
Reply:Originally Posted by docwelderwould the weekend hack mind if the professional welder steals his chop saw idea?? i like the adjustment concept so you don't have to tear it down if you get a different saw. excellent job!
Reply:That is really cool.  Great work and well thought out.I just had my last roomie move out.   I actually have tons of room in the garage again.   After almost 4 years i can create a shop.   Other bonus is I have 2 electric panels and 2 single phase 230v or 240v 50 amp breakers just outside the door.   One for the a/c that I never use and the other for the hot tub that definitely does not get used because its old the pump froze a few winters ago before I moved back and very expensive to run. about $10 a day. It's gas heated and was not insulated well.   Anyway's Once I get other things cleared out I need to make a dedicated table one for welding and one for plasma cutting.   That is a great design.  I know just where to put it too.  “I'm going to do the thing that God put Galen Beasley on this Earth to do:Have Salon quality hair and weld.Nothing like a good cup of coffee and the smell of 6010 burning in the morning. 971-204-3444 cell API ASME Structural NDT and RepairOriginally Posted by 7A749Don't think any ships are gonna be fitting in there Galen!!!!

Reply:That's sweet. I need one with a hydraulic lift and a timer so that it will dump all the crap on it every two hours. When someone builds a table that doesn't become a "catch-all" for the junk in my shop I'm going to buy 2 or 3 of them.

Reply:i worked alongside a welder who turned his work table into a motorized work bench,  battery powered and had wired controls for power and steering.  it was quite a sight to see running around the jobsite . awesome table in this thread too .
Reply:Just wanted to add...Electricity does not "return to source," it takes the shortest path to ground. (Otherwise lightning would never happen, and caps would never burn.)Important note here. If you have multiple paths to ground, the electrons don't have a notion of which one is the "correct" or "source" path they came from. They use whatever is easiest. The only thing that would change how much voltage goes either way would be something like a difference in resistance. Make one path harder, the other is favored.Having the boxes mounted directly on the table is an issue. The box is by design grounded to the building ground. The box is electrically bonded to the table, which in turn is bonded to a hefty power circuit, aka welder, which is on a completely different circuit. (Unless you are welding with Oxy-Acetylene, of course. )Example 1: Assume your welding circuit ground IS truly a ground and not a common lead connected source of power. That means that you ARE using the ground to carry current. If the welding table is electrically connected to both the 110 volt ground and the common lead that the welder is connected to, your return voltage gets split between the two. Consider that if your work electrode is a ground, and you only have one stinger its almost certain both poles are being rectified and combined. With that sort of EMF you can easily burn through household 110 volts wiring and start fires.Example 2: Assume your welding circuit ground IS NOT truly a ground. You end up pushing current across the ground of the table because it is bonded to the same bus in the main junction box of the main panel. (I won't mention the obvious problem of the welder having welding leads connected at least in part to the cabling that powers the welder.) This is a violation of code, regardless of the cause.The rule of thumb that gives a common sense perspective of this issue is one that seems to work even when it does not seem to make sense. There can only be one path to the ground bus in the main panel from any part of the circuit, ever. Anything that could represent a loop or give rise to common current traveling across the ground is inherently bad. Even physically connecting two steel electrical boxes from different circuits represents a potential for risk. I was very resistant to this for many moons. I'd think up "what ifs" like, what if I were living in a steel box and not a wood frame house. But then notice that people living in steel boxes have surface mount conduit and the box becomes the ground!I would not connect the convenience outlets when welding. I would not weld when the convenience outlets are connected. If you want to use both the best bet would be to get an electrician to check and bless it and give some guidance on the safety aspects. I am no electrician, but have created that sort of mess accidentally before. Learn from my dumb@$$ mistakes and avoid making the same ones. I was lucky to be isolated in a basement with no flammable stuff around. If I hadn't been, I would be at the bottom of an ash bucket today.
Reply:The outlet boxes are PVC or some other insulated material.

Reply:Originally Posted by kaldIt would be  fine if the boxes were metal. In fact with that set up they probably should be metal. .... The welder, table and outlets should be grounded.

Reply:Originally Posted by DukerAs the builder of the table being discussed I am taking a keen interest in this topic as I want to be sure I am being mindful of all of the issues concerning grounding. The last thing I want is another thread starting and  discussing my demise with the gist being " he made a decent table to bad he electrocuted himself on it!" I read through the links you provided and it appears I am adhering to their point on grounding. As M J D and others pointed out the convenience electrical boxes are isolated from the table and the boxes themselves are grounded to the panel when plugged in. The table itself is grounded when welding as I have grounding tabs that I attached the ground clamp to when in use. This completes the circuit so the ground is as described again in the links provided. I am not sure how else or where else I can improve but if I am overlooking something I want to be aware and fix the situation. Thanks to everyone for the comments.
Reply:Originally Posted by kaldHey Duker,Your welder ground that you are referring to is actually the “workclamp” not the “ground”. Two separate circuits.  Your tableshould  be grounded in addition to having the work clamp attached. In no way is your table grounded with only the work clamp attached.
Reply:Originally Posted by DukerKald, thank you for the info. I can make up a separate ground clamp to connect the table to a ground rod I have right outside my garage. Better safe than sorry and it's an easy fix.
Reply:The welder is grounded through the NEMA 5A plug.  The convenience outlets are grounded through the ground wire in their cord. The electrical ground, NOT welding ground, is there to trip the breaker if a hot wire should contact grounded metal.  If your table is ungrounded, a hot wire in the convenience outlet loosening and coming in contact with with the table could make it a 120V table.  If you touch it with wet shoes you may become the path to ground.  I think the table should be grounded.  If it is, and the hot wire contacts it, it will trip your breaker alerting you to a dangerous condition.
