In regions affected by extreme heatwaves, traditional welding equipment often struggles to maintain stable performance, especially in high-temperature environments. This poses significant challenges for factories, leading to delays and reduced productivity. STRION LASER’s innovative solution to this problem is its refrigerant-cooled handheld laser welder, which delivers reliable performance even in temperatures exceeding 60°C. This article outlines how STRION LASER’s breakthrough technology ensures continuous and stable welding output in the face of extreme heat.
Overcoming Heatwave Challenges in Welding Equipment
Recent heatwaves across the country have pushed temperatures above 40°C, exposing the limitations of conventional welding equipment. Traditional systems—whether air-cooled or water-cooled—struggle to perform efficiently in such extreme conditions.
Conventional Air-Cooled Handheld Welding Machine
At an ambient temperature of 35°C, cooling efficiency declines significantly, and at 40°C, intermittent shutdowns disrupt continuous production, hampering workflow.
Water-Cooled Handheld Laser Welding Machine
Even at an ambient temperature of 50°C, the water-cooled system’s capacity to cool the welding torch drops sharply, leading to frequent shutdowns for maintenance.
STRION LASER’s Breakthrough Solution: Dual-Loop Refrigerant Direct Cooling System
STRION LASER’s innovation addresses these challenges with a dual-loop refrigerant direct cooling system integrated into its high-power handheld laser welding machines. This award-winning technology, developed to overcome the limitations of traditional cooling methods, ensures stable equipment performance even in extreme heat conditions.
Key Innovation: Dual-Loop Refrigerant Cooling
STRION LASER’s refrigerant cooling system features a precisely engineered internal structure. High-efficiency copper tubes are embedded in cooling plates that are tightly bonded to key heat-generating components. The compressor pressurizes the refrigerant into high-temperature vapor, which is then condensed into liquid form by the condenser.
Enhanced Cooling with Variable Frequency Control
The dual-loop design combines refrigerant cooling with an intelligent fan controlled by a variable-frequency algorithm. This system dynamically adjusts cooling output based on ambient temperature and welding power demand. As a result, the equipment remains stable even in temperatures exceeding 60°C, ensuring continuous, reliable laser output.
High-Power Integrated End-Cap Design
Additionally, the high-power integrated end-cap design of the welding gun reduces optical path scattering loss and internal heat generation, improving heat dissipation efficiency. This ensures that the welding gun’ s body temperature remains controlled, contributing to consistent and stable welding performance.
Live Performance Test Under Extreme Conditions
To demonstrate the effectiveness of this technology, STRION LASER conducted a live public test on July 17, 2025, at 14:30. The test simulated a high-temperature workshop environment with no air conditioning or auxiliary cooling. The handheld laser welder was subjected to a full-power, continuous 2-hour output stress test, with key performance data monitored in real-time.
Test Conditions:
Ambient Temperature: Simulated high-temperature workshop environment (no cooling applied)
Chassis Surface Temperature: Continuously rose to 72°C (peak measured value)
System Status: No alarms, shutdowns, or power fluctuations during the test
Results of the Test:
Stable Welding Process: The molten pool remained steady, and wire feeding was consistent throughout the test.
Qualified Weld Quality: On-site inspection confirmed that weld penetration, width, and formation met process standards.
No Performance Degradation: The welding performance remained the same as under normal temperature conditions, demonstrating the reliability of the equipment.
Conclusion
STRION LASER’s dual-loop refrigerant cooling system provides a groundbreaking solution to the challenges posed by extreme heat. By maintaining stable welding performance even in temperatures above 60°C, this innovation ensures reliable operation for factories facing high-temperature conditions. STRION LASER’s commitment to developing advanced, high-performance welding solutions continues to set the standard for the industry.
