Re: Damage to electronic devices as raised about Digital Electronic Vernier Calipers.

David - there is no simple Y or N, sorry. But since you asked -
"Then the TIG Arc causes/releases a large amount of unrefined/uncontrolled
Radio Frequency (RF) signals." Y N Maybe Sort of, it is actually a spectrum Y "This then swamps and damages any
electronics in the vicinity. Am I correct? Y Maybe Maybe
The power of the TIG arc (welder) and the distance to the piece of
electronic equipment, increases or decreases the risk of damage. Generally Y
Does that mean MIG is not so bad, as it has a sacrificial electrode? N Doesn't matter Any arc (mig, tig, plasma cutters, arc lamps in theaters, Jacob's ladders, Tesla coils, Neon lights, spark plugs, etc.) will generate electromagnetic radiation. Whether the electrode is consumable or not is immaterial. It is the arc which is formed when the voltage between the electrodes is enough that the electrons on one electrode can jump to the other that causes the radiation. The strength of electromagnetic field is much higher in some arcs than others. The sensitivity of the electronic device will vary without any way to quantify. The error induced in an electronic device might be a simple as a color changing from FFFFFF to FFFEFF (which your eye could not notice) or it might change something where that bit makes a machine instead of moving 0.010mm it thinks the move should be 10.01mm. When there is excess radiation near an electronic circuit (which is more susceptible than some other things), the radiation can enter the circuit and create voltage levels that make the circuit do unpredictable things. That is the annoying side of the problem. If there is enough radiation that causes the circuit to become unstable then damage might occur. Then the next level is when the radiation is even higher and the circuit is damaged directly by the induced current. Then there is the case of more severe radiation, such as an EMP (electro-magnetic pulse), which generates enough radiation that motors and transformers might see excessive current and become damaged.

Probably not Johannes’ problem, though…:-)
My shop is lit by LED bulbs or fixtures I got at Costco 4
or 5 years back to replace the old flickering ?fluorescent
ones; but I haven’t noticed any issues in use ?with my
calipers until the batteries get low, which produces just
those kinds of weird issues.?

When I GTAW the HF start really messes with all of my DRO's, and digital calipers/micrometers. ? It turns them on, turns them off, the displays show erroneous readings.? I thought they were possessed until I figured out it was the TIG's HF start that was causing the problem.? ?
