Cougartron marking spares and accessories – A complete overview

Thanks to the effective utilization of the electrochemical method, Cougartron machines deliver outstanding results with metal marking and etching.

The electrochemical process is based on a combination of electrical current and special electrolytic fluids.

This principle remains the same regardless of whether you use one of our dedicated marking machine sets or upgrade sets for our weld cleaners.

The items in both sets are easily replaceable if damaged, but there are often many doubts and uncertainties about their use and compatibility.

This is one of the main reasons why we decided to do a simple but detailed overview of our marking spare parts and accessories.

But first, let’s look at the difference between our marking machines and etching sets.

The difference between Etching sets (for weld cleaners) and Marking Machines

Cougartron marking machine sets contain a power supply unit and all other parts and accessories required for successful marking.

An example is our popular MK12 machine which proved to be extremely useful in a number of different industries.

We have also recently added a new machine to our product range – the MK612 was developed specifically for efficient marking of larger surfaces without losing color consistency.

Unlike our machine sets, the marking/etching sets only contain components that are used to upgrade our weld cleaning machines. 

With the addition of a couple of special components supplied within the sets, Cougartron weld cleaners become as effective as our dedicated marking machines.

Our Basic Marking/Etching set is compatible with all Cougartron weld cleaners (including ProPlus machines purchased after November 2019)

Unlike the Basic set, the ProPlus Etching set uses a footswitch and is only compatible with ProPlus machines purchased prior to December 2019.

It is worth mentioning that due to the specificity of the electrolytic method, both sets and machines require the use of stencils and special marking fluids.

The stencils are either disposable (prepared with label printers) or reusable (supplied by Cougartron according to your design).

Our machine sets and etching sets contain small quantities of marking and neutralizing liquids (0,1qt of CGT-S1 and CGT-N1) to get you started with effective marking straight away but you can always top up your supplies here.

Note: The CGT-S1 fluid is only suitable for marking stainless steel. We offer a variety of liquids with formulas adapted to various metal surfaces.

Both stencils and fluids are re-purchased on a regular basis – just like our etching felts, which you can read more about below.

Note: All machine set spare parts have been recently renamed from MK12 to MK since they are compatible with both our machines – MK12 and MK612.

Clamp cable and the etching cable for the handle

As the name suggests, the etching cable for the handle connects the handle (and the marking electrode) to the marking unit.

The clamp cable connects the grounding clamp to the machine housing.

Both cables are compatible with our marking machines (MK12 and MK612) but are not required when using the Basic marking/etching set.

Etching clamp

The etching clamp is attached to the workpiece and is compatible with our MK clamp cables.

Since our weld cleaning machines are equipped with their own clamp, this item is not used with the Basic Etching set.

Cougartron MK Marking Head (Without Adaptor)

The MK Marking head without an adaptor is used exclusively with our marking machines – MK12 and MK612.

This component is in a semi-direct contact with the work surface and connects to the MK handle.

Dimensions – 1.5×0.5×0.9”

Cougartron Marking Head with Adaptor

The marking head with an adaptor is a common component to both of our etching sets and cannot be used in combination with our marking machines.

The adapter is an exclusive component of our etching sets and connects to the handle cable of the weld cleaner that also serves as a marking handle.

White etching felt

The white felt is compatible with our marking machines and both etching sets. It is positioned under the yellow felt when assembling the marking head.

Always keep in mind that the white felt should not be used in combination with the carbon felt.

Comes in a pack of 10.

Yellow etching fabric

The yellow felt is used in combination with the white felt and is positioned on top of it when assembling the marking head.

This type of felt is most commonly used by our customers and is more affordable than the carbon felt.

You can also combine the yellow felt with the carbon felt when it comes to high-volume marking projects. However, with most marking activities, the combination of white felt and yellow fabric is sufficient.

Comes in a pack of 10.

Carbon etching felt

The carbon felt is used in combination with the yellow fabric during high-volume projects when you need to increase the speed of your process.

This also makes the carbon felt more durable and protects the marking stencil from being overly damaged.

Please note that the yellow felt should always be placed on top of the carbon one.

This type of felt can be used with our marking machines and the etching sets.

Cougartron O-Ring

The role of the O-ring is to hold the electrode adaptor and the etching felt together.

Similar to all other components, this one must also be replaced as soon as possible if damaged. However, O-rings are durable and can normally be used during hundreds of marking sessions.

The O-Ring is compatible with our marking machine sets as well as with etching sets for our weld cleaners.

This product is sold in packs of 5. Our machine sets contain one O-ring while 5 of them are supplied within our etching sets.

The etching handle is used to control the movement of the marking head during marking.

Our weld cleaners are equipped with a handle cable which is compatible with the adaptor connected to the marking head.
