This guide is for a wand that has already been through a proper safety overhaul by a qualified person (see Violet Wand Safety). If yours hasn't, stop here and keep it as a display piece for now. Nothing below is about using a wand on a person. It's about watching it work, learning its quirks, and recording how it behaves.

Set up your bench#

  • A clear, dry, non-flammable surface. No paper, rags, solvents, aerosols or hand sanitiser nearby. Sparks will find them.
  • Good ventilation. Open a window. Running wands make ozone.
  • An RCD-protected socket, or the isolation transformer your restorer recommended.
  • A padded tray for electrodes waiting their turn.
  • Nobody with a pacemaker or other implanted device in the room, and pets elsewhere.
  • A notebook or your phone for recording what you see.

First power-up#

  1. Check the wand's voltage rating against your supply one last time.
  2. Fit a sound electrode you don't mind about. Keep your best glass in the case for now.
  3. Turn the control to its lowest setting.
  4. Hold the wand by the handle only, with the electrode pointing away from everything.
  5. Switch on and watch.

Expect a buzz, then a glow inside the electrode. Bring the control up slowly. The glow should brighten, and the buzz may change pitch.

Switch off after a minute or two and feel the handle. Gently warm is normal. Hot isn't.

Reading the glow#

  • Even violet or purple throughout the tube: a healthy argon or mixed-gas electrode.
  • Orange-red: a neon electrode. Perfectly normal if that's what it is.
  • Faint, patchy or flickering that settles after a minute: common in electrodes that haven't run for years. See Charging Electrodes.
  • Pale blue-white or pinkish haze, or a glow only at the very tip: the electrode may have lost its vacuum. Retire it.
  • No glow at all: try a known-good electrode before blaming the wand.

Reading the buzz#

  • A steady, even buzz is what you're after.
  • A rough or stuttering buzz often points at worn interrupter contacts.
  • Crackling inside the handle, or a smell of hot Bakelite or burning, means switch off and unplug straight away. Something is arcing where it shouldn't.

Sparks at the bench#

With the wand running, bring the electrode slowly towards a metal object, such as a large screwdriver held in its insulated handle, or an earthed metal plate. At a few millimetres a small spark will jump. Notice how the gap at which sparks start changes as you turn the control. It's a nice, simple way to compare output between wands and record it over time.

Keep the sparks brief. They're hot, they make ozone, and they can pit metal and electrode tips.

Keep a log#

For each session, jot down:

  • date, wand and electrode used
  • control setting
  • glow colour and evenness
  • buzz quality
  • how warm the handle got, and after how long
  • anything odd

A few sessions in, you'll know your wand's normal, and you'll spot it when something changes.

When to stop#

Switch off and unplug if you notice burning smells, smoke, a hot handle, crackling inside, a flickering mains light, or a cracked electrode. Then get it looked at again. How Long Can I Run My Violet Wand? covers rest breaks.
