This gold pen plating kit includes just the essential items you need to make a start with pen plating. Our Gold Pen Plating Solution is developed in-house and contains 12 grams of gold per litre.

Not suitable for plating on non-conductive surfaces.

For further products related to this gold pen plating kit, please see below in our “Related Products’ section.

The gold pen plating kit is built around our MF Rectifier. This is a multi-function rectifier and so can be used for brush and tank as well as pen plating. For a guide on how to set up your MF Rectifier for pen plating,please click HERE.

Our Gold Pen Plating Kit is ideal for small gold and silver plating jobs on jewellery. We’ve included two of our fibre nibs as well, for rhodium pen plating  and gold pen plating on to difficult to place alloys such as chrome, surgical steel and dental alloys using our Gold Strike Pen. You can see a guide HERE in our Electroplating Manual on pen plating. This kit (or any of our other kits, equipment or solutions) is not suitable for plating on to aluminium or titanium and therefore can’t be used to plate iPhones and other similar products.

The plating pen features a removable and exchangeable platinum electrode. This allows you to properly clean your plating pen after use and before storage. It also delivers the flexibility to choose between our range of pen electrodes in silver, copper, nickel and carbon, matching it according to the solution you’re intending to use.

Our Pen Plating Clip Tray connects to the MF Rectifier and frees up one of your hands for presicion pen plating. It also catches any run off from your pen plating solution, allowing you to use these drips again on your plating job. Full details of the clip tray can be seen HERE.

To clean your Fibre Nib, simply hold it under running water for a minute or so.

Setting up your MF Rectifier for pen plating

This rectifier can be used for tank, brush and pen plating. Here is a quick guide to setting it up for pen plating.

1. Your equipment

Setting up your MF Rectifier for pen plating is a straightforward process. Assemble your equipment as shown in the photo. For this demonstration, we’ll be using our plating pen.

2. Turning on your rectifier

Use the switch on the back of the rectifier to turn it on.

3. Attaching the leads

Fit the copper crocodile clip to the end of the black lead and plug the other end into the corresponding black socket on the front of the rectifier. Plug in the red lead into the corresponding red socket.

4. Amps and volts

Turn the amps dial anticlockwise to the stop (minimum) and the volts to the value required by the pen plating solution.

Note: Even though the amps dial is set to maximum, the amps meter will read ‘0.00’.

5. Open the circuit

Open the circuit (or turn the circuit off) by switching the Output switch so that the line is in the up position.

6. Set the voltage

Set the voltage to about 3.5

7. Connecting the black lead to the red lead

Using the crocodile clip on the end of the black lead, connect the black lead to the red lead.

8. Close the circuit

Close the circuit.

9. Adjusting the amps

Adjust the amps to about 0.4 to 0.5 amps.

Note: This stage sets the maximum amps to prevent damage to the work piece should the bare electrode accidentally contact the work piece directly

10. Open circuit

Open the circuit again.

11. Connecting the plating pen

Unclip the crocodile clip from the end of the red lead.

Connect the plating pen to the end of the red lead.

12. Selecting voltage

Select the correct voltage range for your plating solution. In this case the solution is our Gold Pen Plating Solution and the range is 4-5 volts.

13. Closing circuit for plating

Now close the circuit and you’re ready to start plating.

Plating Durability

‘Hard’ vs ‘Soft’ gold plating


Hello, can you advise me re durability of plating types. I have a battery pen plater and it’s great for detail on jewellery and I apply to vermeil standard but another jeweller said pen plater plating is not as durable/is softer than tank plating. Can you confirm if this is the case so I know which direction to go with my new kit.


Thank you for your enquiry.

The type of plating solutions we sell are hardened but then saying that, they are still quite soft when compared to other metals like copper and brass.

For any given thickness, pen plating is just as durable as tank-plated gold. The important thing is the thickness.  Thick deposits can be built up with both pen and brush plating, but it may take a lot longer depending on the surface area and shape of the article you are plating.

It is possible, using our online calculators, to estimate how long it would take to pen plate Vermeil gold (2.5 microns). Once you have established the surface area of your work piece and knowing the thickness (2.5 microns) it is possible to input these into the calculator and get an estimate of time plated.

I have just done this for a ring of surface area 8 square centimetres and the time to pen plate it to Vermeil standard is 95 minutes (just over one and a half hours), while the time to tank plating it is 22 minutes.

So if you’re going for Vermeil-standard work, it may be the best idea to look at out tank/beaker plating kits.

Kind regards
