RE: [CAD_CAM_EDM_DRO] Variable Transformer

Alan:

I hope you don't mean to imply that because I wish to ask questions, and
discuss it, that I am NOT concerned with safety?

There are many different kinds of people-some will take a "NO!" as gospel,
others want to know why. If you won't tell them why, they may just try it
anyway-if it IS dangerous, they may get hurt.

Dissuade all you want(or think you should) but when somebody asks a
question, just restating "Because it's dangerous" is not very helpful, in my
opinion.

Hi Dave, list,

Yes, that's quite true! And we are all greatly concerned about SAFETY, thus
the rather curt "NO" in many (including mine) responses. And yes, we've
seen this question many times before, and yes, we will continue to dissuade
members from using VARIACs without isolation transformers.

VARIACs are a good way to adjust line voltage. I've done it myself for
testing a Vextra cw/ccw driver that wanted 100V. Long term solution is to
use a bucking transformer in series with the primary.
