If these components have been damaged to the point of allowing dirt and dust to enter, the damaged front or rear cover, or both, must be replaced. After polishing the knob it is again washed to remove any residual polishing compound and then dried. This thin film of detergent genrax “ionic” and “hygroscopic” and absorbs moisture from the air forming a conductive path to discharge any acquired static charge. All of the sheet metal or cast housings and case components covers, “shields”, dial-plate, mounting plate, etc.
Everything looked fine when it was submerged and when it hit air, this happened.
The power cord brass plug-tips are brightened with sandpaper and soap-filled genead. All threaded holes in castings are “re-tapped” with the appropriate machine tap using a custom-made power tapping tool. The front and rear meter case components when assembled are designed to form a “dust-tight” seal to prevent environmental contamination.

Since the genrda used in variacs are genrwd AC voltages and amps or watts, the specific type of meters most commonly used are of the “iron-vane” design and as such are susceptible to erroneous readings from external magnetic fields, the exact magnetic fields produced by the variac itself!
Before restoring any of these components, these parts must be washed with detergent, thoroughly rinsed with hot water and oven dried.

I perform a full initial evaluation including a “triage” test for operation of all controls and output range for volts and amps, meter functions plus a 1,volts AC “HI-POT” chassis leakage test. Pretty short throw, but actuation is about at the normal level, you just need to nearly bottom out so there’s almost no overtravel.
When the variac is equipped with a single-or multiple-analog meters, these will need to be individually cleaned and calibrated. Add to watch list Remove from watch list.
A long, very thin, camel’s hair brush, fully filled with paint, is tipped into the cursor recess allowing the paint to flow through “capillary” action to fully fill the recess.

All of the restored components are carefully re-assembled in a specific sequence determined in advance by the ease, accuracy and cosmetic protection required for each element or assembly.
New, properly-rated fuse holders are installed and gennrad internal wiring that will be soldered, is secured mechanically prior to soldering. Either way, should be a good opportunity for someone else to find out just how genraf these switches are with the right foam and setup.
