What are the Necessary Components of a Welder Chiller?

The necessary components of a Welder Chiller are listed below:


Situated between the evaporator and the condenser, it deals with compression of the refrigerant so that the intermolecular spaces decrease, increasing the pressure and reducing the volume.

A high-power electric motor can also be used to provide the driving force.


It is responsible for the conversion of vapors into the liquid state. It is located after the compressor and before the expansion valve.

The two main types of condenser fan include a water-cooled and an air-cooled type.


It works by vaporizing the refrigerant. This process takes the heat from the welding process and incorporating it into the evaporation, so the particles gain energy and break free from the rest of the refrigerant.

It has a large surface area for more exposure of the upper surface particles as they gain energy and vaporize.

Expansion Valve

Rapid temperature reduction and volume increase are obtained by allowing the refrigerant to expand in the expansion valve. This process again absorbs a significant amount of heat.

Water Tank

It can be directly mounted to either the evaporator or condenser. The purpose is to obtain a separate inlet and outlet for water flow. It helps in better circulation and thermoregulation.

Microprocessor Central Unit

Equipped with the recent technology and touchscreen, it enables you to adjust the required values to achieve the required temperature. It comes with built-in memory and a thermostat for better temperature control.

The direct control of the alarm system and the memory is also in the central microprocessor.

Welder Chiller Screw Compressor

What is the Working Principle of a Welder Chiller?

The working principle of a Welder Chiller is based on the circulation of the refrigerant through the distribution coils allowing expansion and condensation, which results in absorbing and dissipating heat.

The absorbed heat is used in evaporation, and the dissipated heat is thrown off to the environment through the exchange in the cooling tower.

As the refrigerant and the chilled water flow through the system, they allow a maximum heat exchange due to high-temperature differences. The greater the temperature difference, the greater will be the heat transfer.

In this way, all the heat from the equipment and the welding process is absorbed and later on dissipated to the environment.

What is the Purpose of Using a Welder Chiller in the Welding Process?

The purpose of using a Welder Chiller in welding is to get rid of the heat produced during the process.

As the surface of the material is welded, and the welding equipment comes in contact, an immense amount of heat is produced to allow the bonding of two surfaces together.

It helps in the prevention of the following factors:

Overheating of Equipment

The equipment is used for long hours and tends to heat up. Heated equipment provides sub-standard welding, and therefore it must be operated at the given temperature.

Breaking of Circuits Due to Overheated Wiring

Due to overheating, the wires tend to melt and break away the connection in the welding machines. It can also be overcome by removing the heat and using insulation.

Magnified Results

Amplified results are guaranteed when the temperature is maintained in a narrow range. Therefore precise temperature control is greatly responsible for the productivity of your application.

Comfortable Environment

The highly heated up environment in the welding industries can lead to poor health and disorientation of the laborers working there.

With good temperature regulation, you can obtain a comfortable environment to get the best out of the workers in the industry.

Refrigerant Level Indicators

Sensitive indicators inside the refrigerant coils detect the lower level to be recharged promptly.


The thermostat in the central microprocessor unit is set at a definite value according to the application process. Any deviation from the set level is indicated through an alarm.


The wires and all the connections are insulated with the help of a strong insulator like rubber or fiberglass. It protects the user and the detection of any excess cooling load.


A good quality antifreeze plays an essential role in places with shallow temperatures. It is most useful in winter.

Glycol Water Mixture

A mixture of glycol and water in the cooling tank provides higher efficiency since glycol acts as a good antifreeze and allows better flow.

Trained Operator

It is best to only allow a trained operator to use the Welder Chiller. All the values shall be set according to the welding process.


  • The chiller needs to run 24 hours a day, even in an extreme environment.
  • The recirculation status of water shall be monitored for added protection because circulating water prevents it from freezing.
  • After every use, especially in laser welding, ensure all the water from the laser head shall be recorded entirely, so there is no freezing in the valves and fittings.

What is the Difference Between an Air Cooled and a Water Cooled Welder Chiller?

The difference between an air cooled and water cooled Welder Chiller is based on the coolant being used in the refrigeration cycle.

Air Cooled

It utilizes the ambient air currents and shielding gas to remove excessive heat dissipated from the welding torch.

It is much more efficient and requires less assembly space. The cold air currents take up heat from the system through the refrigerant, which flows through the condenser coils.

Then this air is either recirculated back into the system, or the heat is vented to the environment directly.

There is no need for a cooling tower, but it shall be installed outside to capture more air currents. It has a minor assembly.

Water Cooled

The excessive heat is removed through recirculating water. A thin power cable is used by the water cooled welding torch. However, it requires higher maintenance as compared to the air cooled type.

The efficiency is high, but it requires an extensive network of pipes for adequate flow through the system.

The cooling tower is an essential component, and it must be installed at a site with a steady water supply.

Air Cooled Welder Chiller

Gas Tungsten Arc Welding

The non-consumable tungsten electrode protects the shielding gas, but it still requires the function of a chiller.

What are the Types of Compressors Used for a Welder Chiller?

The type of compressors determines the capacity of the Welder Chiller, and therefore it must be selected wisely.

Scroll Compressors

It uses a field and an orbiting scroll for continuous refrigerant compression. It deals with average cooling loads such as small industries and processes where welding is necessary.

Screw Compressor

It is also known as the rotary compressor. It utilizes two rotors to move the refrigerant from very low to very high.

The screws or rotors lock the compressed gas in a confined area. It works best for applications with medium cooling loads.

Centrifugal Compressor

Centrifugal force is used in this compressor to compress the refrigerated vapor. It deals with moderate to large cooling loads such as large industries that require continuous welding.
