I cannot answer your question yet but I wanted the same answers.
Originally I looked for industrial 3 phase power meters but these were very expensive.
Due to the appearance on the market of domestic energy meters (some energy supply companies give them away free) it is possible to buy low cost three phase energy meters.
So for about £65 we purchased a CC128 ENVI from http://www.greenandeasy.co.uk/ (see energy saving devices)  with 2 extra CTs. The manufacturers website is http://www.currentcost.com/ .
We are only just using it but it was purchased to answer the questions about the most cost effective way to run our equipment. Had we had it a week earlier we would probably have discovered the reason for our wave's overshoot ourselves.

Subject: [TN] Energy Usage of Equipment

Oh wise and informative Technetters,

John Goulet posted a few days ago about using a thermal blanket and reducing the temperature of the wave solder bath to just below MP in order to reduce wear on the heaters while keeping costs low. 

Does anyone have any information on how much power is consumed by the typical wave solder pot in heating the solder from ambient, and how much is required to run steady state? What about reflow ovens?

We are looking at our energy costs here and ways to reduce. Currently we shut the machines overnight, and they turn on by timer 2 hours before the shift starts. We are a one shift operation.

Thanks,

Blair
