How to use your Cougartron weld cleaner to mark metal
Updated – August 10, 2020
Cougartron’s weld cleaning machines are primarily intended for activities such as rust removal and surface passivation.
However, you can use our weld cleaners for effective marking and etching as well.
But how is this actually possible?
Both processes use electricity and electrolytic liquids to obtain the desired results.
Thus, the difference between electrolytic marking and weld cleaning is subtle and mainly concerns the way the metal surface is affected.
You can transform your weld cleaner into a marking machine by slightly adjusting your work process and adding specialized accessories to your equipment.
So, what is the actual difference between the equipment used for cleaning and marking?
Equipment required for electrolytic marking
1. Cougartron Marking Head:
One of the main differentiating points is the use of marking heads instead of weld cleaning fiber brushes. Thanks to a special adaptor, the marking head is easily screwed into the handle cable that normally holds the weld cleaning brush.
To ensure the effectiveness of the marking process, you must combine the marking head with a white felt and yellow fabric. The assembly is secured with Cougartron O-ring. All the mentioned items can be found within the Etching set.
2. Marking Fluids:
In addition, you also have to use specially developed marking acids instead of regular phosphorus-based fluids we use for weld cleaning. Marking fluids are also mild and low-risk but have a slightly different chemical composition.
The Basic Etching Set contains CGT-S1 (Stainless Steel Marking Fluid) and CGT-N1 (Neutralising fluid), but thanks to a wide range of Cougartron Marking Fluids, it is possible to mark onto any metal surface – aluminum, mild steel, copper, zinc, nickel, brass, and even titanium.
3. Marking Stencils:
Their role is to transfer your design pattern (e.g. logos, dates, part numbers) to the metal surface. Stencils are independently printed or made to order. Cougartron offers two types of stencils – single-use and multi-use. The multi-use stencil can last up to 2000 uses and it’s ideal for marking logos and designs without changing production information. Multi-use stencils are custom made and the price is calculated based on dimensions and design. The single-use stencils are to be used for information that keeps changing such as dates and part serial numbers. They are produced using specialized Label Printers.
4. Label Printers:
Label printers are used to produce single-use stencils for electrochemical marking. They are either stationary or handheld – but always lightweight and convenient to use. Depending on their size and capacity, the printers can provide a variety of stencil sizes suitable for common marking applications.
COUGARTRON ETCHING SETS AND HOW TO USE THEM
COUGARTRON BASIC ETCHING SET
The video below demonstrates the use of the Basic Etching Set and provides a detailed guide on the utilization of its components.
The Basic Etching set is compatible with all Cougartron weld cleaners including ProPlus models bought after November 2019.
The set has been updated to include a pack of 10 white felt sheets instead of the etching roll (eliminates the need to cut fabric to size) – and we’ve also added a yellow fabric for improved marking performance.
NEW! – Use Cougartron ProPlus together with the Basic Etching Set
We have made the new ProPlus models compatible with the Basic Etching Set for improved user experience and workflow. You will no longer have to use the footswitch found within the ProPlus Etching set. However, you can still purchase the ProPlus Etching set (along with the footswitch) for use with older ProPlus machine models (purchased before December 2019).
The ProPlus is equipped with two marking functions which makes it different from other Cougartron weld cleaner models:
- Unique Marking Timer Settings – 5,10, and 15 seconds work intervals suitable for different marking requirements
- Continuous marking – Shared functionality with other machines, the marking head remains active until it’s switched off manually.
Our new video demonstrates effective marking with ProPlus and the Basic Etching Set – and shows you how to properly use the timer settings in different production situations.
COUGARTRON ETCHING SET WITH FOOTSWITCH (FOR THE OLDER PROPLUS MODEL)
The set contains a special footswitch pedal and is only compatible with ProPlus machines purchased before December 2019.
