Variac input/output current

[Phil Allison]

Yep I barely have any idea how much it draws, I bought it off ebay and don't
have it here yet. I will start a new thread when it arrives and I have more
details...

** Do you even know it is intended for 120 volt ???

I wish
You arent factoring the super high efficiency of argon lasers... 1000W in,
~50mW out.

** A brief Google search shows that argon lasers are appallingly
nefficient - less than 1% in fact.

However, a 1kW argon tube should deliver about 2 to 5 watts of laser
light - enough to be ***VERY*** dangerous to people's eyes.

Nope, this one is rated for 40mW at end of life at 10A, doing around 60mW
now apparently. Multi-watt argon lasers usually need 3 phase power and water
cooling.
Sam's laser FAQ is the bible of hobby lasers, see there if interested.

Yes, that is one of the few things I know. Single phase 110-120V AC for
sure.

** Ones for sale on Ebay now give close to 0.1% of the DC input power as
laser light.

Your one is a real slug at only 0.006% !!!!!!

** It most probably has no transformer of it own and just rectifies and
filters the incoming AC supply.

Could draw anything up to 20 amps **rms** at 120 volts AC to produce 100
volts DC at 10 amps at the tube.

Heh, you might need to consult with Mr Arpit regarding economical domestic
high-current, single phase connections
