How Coolant Controlling Method Works in Automation Welding

In the metalwork industry, high surface finishes are essential to make the finished item look appealing. That is why many workshops are now focusing on machining capabilities. A coolant flow meter is among the devices that contribute to high surface finishes. In automation welding, the coolant must be kept in an excellent condition to produce high-quality parts, which contributes a lot to the company’s bottom line. Many workshops prefer coolant control because it is cost-effective. 

Using high-quality coolant is essential as it limits the amount of old, unusable coolant produced. Proper maintenance helps to increase the tool’s lifespan. Devices and tools used in automated welding are costly. Premature wear of metal cutting tools and welding machines is usually caused by overheating due to friction. If coolant controls are not checked and replaced, the operator may be forced to return tools to do constant breakage. Most shops neglect coolant maintenance leading to a high operation cost when tools are replaced now and then. Checking coolant control conditions to ensure that the fluid is at optimum operating levels can be a lifesaver. 

If you want to get the best out of a coolant flow meter, you need to consider these factors:

Concentration Levels of the Coolant Control Fluid 

Coolant control comes in many types and brands. Each type has a different concentration level. Therefore, the operator needs to follow MWF manufacturers’ guidelines to get desired results when using different types of coolant control. Coolant is heavily used when machines are in full production mode. It is, therefore, up to the user to check whether coolants are still in optimum condition. The best concentration is achieved when control fluids are mixed properly. 

Concentration levels are checked and measured using a refractometer. When operators fill the coolant tank with water as the water level drops, it offers a great challenge to the user. Adding water to the coolant thins it, making it less effective. Issues will start arising when there is little, or no coolant left. No issues will add mods coolant to the concentration, but using new more coolant reduces the return of investment. The most cost-effective way is to maintain the concentration level to boost productivity. 

Check Out for Contamination 

Machines, whether old or new, leak oil. The old ones leak oil because they are old. New ones are made to leak for a reason. A danger looms when oil mixes with the coolant system. Bacteria feed on oil. Therefore when much oil mixes with coolant, it breeds many bacteria, which contaminates the coolant. Waste from bacteria attacks the coolant, which causes it to split. 

This reaction reduces the coolant’s effectiveness. Besides that, tramp creates mist in the air, leading to a shorter cooling flow meter lifespan. Many issues tramp oil brings. Therefore, the best thing to do to prevent these issues is to regularly check and change contaminated coolant. 


When using coolant control in automated welding, filtration is required. Most tools have a mechanism that helps trap debris and small solid particles left behind in the envelope when cutting or welding metal. These solid particles build up in the envelope until they are removed physically—greasy junk forms when debris builds up and is not removed. 

This reaction breeds anaerobic bacteria, making the coolant smell bad. The becomes awful, and there is nothing you can add to the coolant to make the bad smell go away. The only remedy to this is to constantly check and remove debris when it accumulates. Getting rid of unusable coolant isn’t enough. The user also needs to clean the tank before adding new coolant. Failure to do so will result in contamination due to bacteria lining formed inside the tank. 

Preventive Maintenance 

The bad smell is emitting from the cooling flow meter to indicate that it was high time to replace the MWF. Initially, there is a way to reduce the bad, rotten smell, which is meant to bring fresh air in the working environment. 

The downside of smell reduction is that users overuse coolant since there is less or no smell to alert them that it’s time to change the coolant. Many people who used to remove used coolant after a month can now go for six months to 1 year without replacing the old coolant. This is not healthy for tool life. 


Many benefits come from using a coolant flow meter in automated welding. However, the user needs to ensure that quality coolants are used to make them effective. We hope you have learned a lot from this article about coolant control and how it works, and you are now ready to apply these tips.
