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.

Ideal for all pen plating jobs such as selective gold plating jewellery, electrical contacts, dental work.

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 Mrk 2. 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.

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

This kit can also be used to plate different shades/alloys of gold using our coloured gold mixing system. Please click HERE to see our Coloured Gold Mixing Kit which contains everything you need to get started with plating the complete range of coloured golds commonly used in the jewellery industry and related trades.

Here’s a quick video showing how to use the plating pen to selectively gold plate with our Yellow Gold Pen Plating Solution;

How to switch the MF Rectifier Mk II to pen plating mode

To get started;
1. Place the rectifier on a firm surface.
2. Ensure the on/off switch at the rear of the rectifier is in the "O" position.
3. Connect the mains socket to an earthed mains socket using the mains cable included.

1. Switch on your rectifier

Switch the rectifier on using the on/off switch at the rear of the rectifier. The switch should now be in the “I” position.

2. The "16v/5A" button

Press and hold the “16v/5A” button until it starts flashing.

3. Setting the current (amps)

Set the current (amps) using the “CURR” dial to anywhere between 1.00 amps and 1.20 amps.

4. Setting the volts

Set the voltage using the “VOLTS” dial to that quoted on your bottle of Spa Plating pen plating solution.


5. Starting the pen plating process

When you are ready to start plating, press the “OUTPUT ON” button which will change from white to green to show the plating tank is powered. The “16v/5A” button will stop flashing.

6. Stopping the pen plating process

When the pen plating process is complete, press the “OUTPUT ON” button which will change from green back to white to show the pen plating circuit is powered off.

Please note that the current (amps) can be very low in the case of pen plating and may be so low (lower than 0.01 amp) that the current (amps) doesn’t register a current flowing – the display atill shows 0.00 amps.
In this case, the only way to check the circuit, is if plating is actually taking place.

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
