hi
i have a question about my spectraphysics sp-168 ar/kr
i´ve had problems with low pressure, so i´ve tried to add gas
to the tube from the bell. but the voltage never raised above 230v.
and now last weekend after being turned on for like 6h at 35A
it went over 242v (@30A)
what should i do to get it down to 235v?
i guess it´s over filled
other times i´ve only used it for 2-3h
please help me
