another stupid question

Will welding on a workbench that is grounded to electricity cause a feedback into my electrical system? The bench is also grounded to 12 volts off of two truck batteries with a trickle charger on them full time. The batteries operate a carbon rod soldering stinger and a homemade set of silver soldering tongs.

Well..

The trickle charger should have a bridge DIODE rectifier in it.. that is a one way valve on the output.. NOISE, now welding arc generates broadband RF that permeates all the building and wiring. A arc is a tiny transformer sometimes achieving thousands of volts.
That actually is the trigger on a tesla coil, a spark gap throwing broadband RF into a open ended coil.

I used to use a High frequency box on my stainless welder to light off without scratch starting.. I would notice the lightning going from my gloved hands to the vice as I welded the tattoo machines.. It never hurt anything other than messed up the neighbors reception on his BOOM BOOM stereo as he drove by..

Will it hurt anything ever?? well now.. does it lightning there abouts? I was running a tesla coil making purple lightning bolts.. the ozone is the plasma conductor coming off the top emitter.. it must have drifted over to a receptacle, it erased "half" the game in a nitendo 3 game.. was kinda funny in a way.. but no telling what else it affected I didn't know about.. FUNNY thing? I read.. if the ozone drifts over to a receptacle, and you are in the "stream" the 120 can flow back up the NO-wire connection and electrocute you.. but.. high frequency-voltage travels on the outside of the skin, or through it.. I burned a pretty lil black spot on my finger where it was arcing that took months to heal..

If by some chance and it has happened to me with an old AC welder, fixed leads. Your grounding lead from the welder is not attached firmly to what you are welding and the welding ground path goes back to the grounding conductor in the outlet box and then back to your welder. Bad news. It will overheat that little #12 green wire in your outlet box, or melt the insulation. Now this only happened once to me and it was an electrical extension cord. I just checked both my welders now with an ohmmeter, they are DC and could not get either lead to read to grounded metal. Your results may vary...?

My shop is pretty small and I'm trying to set it up to be able to weld inside. I've been looking and can disconnect the power including the ground to the table. My next question is how far from my computer should my machine be? Considering the RF, should I turn it off anyway? I've had it pretty close through the outside wall with no problems.

Believe it or not, I have welded in the shop when my laptop was running a program on a CNC router and it never missed a cut. If you are welding on your steel work bench and can un-plug the outlet or disconnect it when you are welding I think that would help by not getting electrical noise or a ground feedback back into your wiring. I wired my shop myself so I know its done right. I'd put the outlet above the workbench on the wood or drywall and then not worry about it. Most of my grinders are 2 wire, double insulated not requiring a grounded outlet.

Exception, when I was TIG welding and used the HF starting it would really screw up the FM radio, I am assuming it would also screw up a computer.
