helps, try plugging the saw into a different AC outlet through a
super-heavy extension cord made of #10 or #12 wire.

I just measured the voltage with a multimeter. The voltage is 210 V.
Once the saw starts, the voltage drops to around 185V before coming back
to 205 till the saw stops. Then, the voltage goes up to 210.


I saw you post this in a rely to my last message. I did not know you're
outside the USA, which means I am not sure what you really have for
power, or if the power company will help you. However, that is still a
huge voltage drop and not normal. You said the saw is 2000W. That's
not all that large and should not becausing such a drop. Some wiring,
maybe the entrance cables are too small...... I dont know what else to
say!

But here's a thought. Get a 12V Deep Cycle battery and an inverter to
convert to 120V AC. Plug the scanner into the inverter connected to the
battery. Then get a battery charger, probably 5 to 10 amp. Charger,
but make sure it's a charger with "overcharge prevention" (shuts off
when the battery is charged). Connect the charger from an outlet to the
battery. PROBLEM SOLVED. You're running the scanner off the battery!
(Of course make sure the inverter is big enough for the scanner, which I
doubt uses very much power).


2000 w is not much. I just remember that the electric meter is rated
10,000 W. Maybe in this case, 2000 W is not that small.

Doh! That's about a 40A service? Even so, if the conductors are
properly sized and everything is in proper order, a 2000W load
shouldn't drop the service voltage 5V.
