Which is the best choice between water-cooled, air-cooled handheld laser welding, and dual circuit refrigerant direct cooled handheld laser welding?

Water cooling, air cooling, and refrigerant, these three types of handheld laser welding machines each have their own advantages and disadvantages; It mainly depends on one's own needs for using a welding machine.

The refrigerant handheld welding machine is developed based on air-cooled welding machines and water-cooled welding machines; Therefore, it possesses the lightness of an air-cooled welding machine, as well as the ability to continuously weld with a water-cooled welding machine; In terms of energy conservation and environmental protection, refrigerant welding machines are also more excellent.

Both air-cooled and water-cooled welding machines have significant limitations in terms of operating environment. When the temperature of an air-cooled welding machine exceeds 35 ℃, it needs to rest and the temperature needs to be lowered. When operating in an environment with water cooling below 5 ℃, antifreeze needs to be added
The refrigerant handheld laser welding machine does not have such restrictions and can operate at -20 ℃ to 60 ℃. The price difference among the three types of welding machines is also very small, and we need to compare prices under the premise of the same penetration depth; The power of the same melting depth refrigerant welding machine is relatively small. I hope it will be helpful to you.

Generally speaking, water-cooled units have a large volume, relatively high applicable power, and high power consumption during working hours. Therefore, they are suitable for working scenarios with continuous working conditions and relatively thick plates. They are also easy to operate with robotic arms, which means they can operate continuously with high power and intensity. Such scenarios are still easy to find;

Air cooling is generally low-power, but the volume of the entire equipment is much smaller compared to water-cooled units, making it suitable for mobile scenarios and temporary repairs. Of course, welding thin-walled parts is also quite suitable;

Dual circuit refrigerant direct cooling handheld, theoretically more applicable. The so-called refrigerant is to use refrigerant with larger heat capacity to replace water-cooled water refrigerant, so that the volume of the entire unit can be reduced. Moreover, due to the sufficient heat capacity of the refrigerant, the weight and volume of the entire welding arm can be made smaller, which will have more application scenarios. However, the corresponding cost will be higher, and the power consumption for long-term use may not necessarily increase much, But the cost of the entire equipment will definitely be higher.
