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

The water-cooled unit has a large volume, relatively high applicable power, and high power consumption during working hours, so it is suitable for working scenarios with continuous working conditions and relatively thick plates. Moreover, it is easy to achieve mechanical arm operation, which means it 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 reduced, 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 significantly. However, the cost of the entire equipment will definitely be higher.
