I'm ready to setup this laser machine...

[Wilbur Harris]

It's a large frame laser with dual tubes, 80 and 100 watt - Shenhui.

How can I tell which wires to connect to which tubes without tracing the wires and then determining which power supply the wire goes to? Prolly a dumb question but it seems OK to me!

Thanks for any help!!

In my thinking......You answered your own question if the wires are not marked.

^^^^^^ This ,excellent advice...even if they are marked, there is enough of a difference between the current and voltage of the 80 - 100 watt to damage the 80, if it was 60 and 40 it wouldn't matter so much.

OK - I'll start tracing the wires...hope I can tell from looking at the power supplies which is which. I'll do that first.....

Thanks!
