24 V AC OUTPUT | 100 VA POWER |
Transformer for embedding foundation into the frame wire. 220 V in, 24 V and 100 VA out — the model with headroom for stainless steel wire.
The voltage you need does not depend on your budget: it depends on the wire in your frames.
01 · HOW IT IS USED
With the sheet laid on the frame, touch the two probes to two different points on the same run of wire — usually the two ends, or the two nails the wire is tied off to — and apply current. The wire heats by resistance, melts just enough of the wax around it and settles into the sheet; the moment you see it, lift off and let it cool. It works the same on Layens as on Langstroth or Dadant: what matters is not the frame format but that the two probes close the circuit through the wire. Work in pulses of 0.5 to 2 seconds, and several short ones beat one long one.
02 · WHICH VOLTAGE YOU NEED
| Galvanised | Conducts well: 9 V or 12 V is plenty. With this 24 V it heats very fast — use shorter pulses |
|---|---|
| Stainless steel | Higher electrical resistance: at 9 V or 12 V the job drags on. This is where 24 V and 100 VA earn their keep |
| Not sure which | A magnet tells you: galvanised is magnetic, good stainless barely is or is not at all |
And it is not only the voltage: it is the power available in VA and the current the transformer can push against the circuit's resistance. That is why this model has headroom where others fall short — and why, on galvanised wire with good contact, it may run too fast for you at first.
03 · WHAT AVOIDS 90 % OF THE TROUBLE
Tension the wire before embedding: slack wire never sinks into the wax and comes away at the first handling. The probes touch the wire, not the staple, the nail or the timber — “it does not heat” and “it takes forever” are almost always poor contact. Do not let the two probes touch each other, which is a short circuit, and do not leave the transformer running with nothing connected. And if you are starting out, do a couple of practice frames: overrunning the pulse overheats the wire and cuts through the sheet instead of bedding into it.
04 · BEFORE YOU BUY
220 V in, 24 V AC output, 100 VA, 50-60 Hz, plastic housing, CE marked and compliant with EN 61558. One thing worth knowing: the probes are slim and have no insulated grip — for long sessions some people add a handle to them, and it pays to check they are firmly seated before each run.
| ✓ FITS | Frames wired with stainless steel, and long runs of frames in any format. |
| ✕ NOT INCLUDED | Foundation or frames: this is the transformer with its two probes. |
| ⚠ ON GALVANISED | It has power to spare: shorter pulses, or you will cut the sheet. |
