Liquid Cooled Tig Welder

This liquid cooled tig welder is a safe and reliable welding machine that uses only water as fuel. It has a rated power of 70 kW and operates on 380 V electricity. Designed for refrigeration copper tube welding and motor lead welding, it requires only pure or distilled water, consuming approximately 10.65 liters per hour. The gas output is adjustable from 0 to 22,000 liters per hour, producing a high-temperature flame of 2800°C. This machine can replace traditional gas bottles such as LPG and acetylene, reducing safety risks associated with flammable and explosive gases.
Weighing 1760 kg, it features a stable, compact design suitable for production lines or standalone use. In addition to refrigeration and motor applications, it is also effective for ampoule sealing, quartz glass tube sealing, transformer copper busbar welding, aluminum welding, furnace combustion, and steel cutting.
 

The main body is constructed from durable, corrosion-resistant steel. Welding joints are precisely sealed to prevent gas leaks. Key gas-producing components are specially treated to withstand high temperatures and pressures, ensuring reliable operation during long hours of frequent welding.
The machine is equipped with a smart liquid-level control system and multiple sensors. At startup, it performs a self-check and automatically monitors water levels. An automatic water-fill hose maintains water supply without interrupting operation, reducing the need for manual refills. When changing the burner, a single tightening of the sealing screw ensures a secure, leak-proof fit. From construction to design, this welder provides stable, precise, and efficient welding performance.

Safety is a major feature of this welder. It includes three flashback arrestors - physical, electronic, and made of specialized materials - along with a certified safety valve, sensitive gas alarm, and real-time temperature and pressure monitoring. A voice alert system adds an extra layer of protection, reducing flashback risks during ignition, welding, and flameout.
This machine also offers excellent value. It requires only electricity and water to produce gas, generating minimal waste and low pollution, which benefits worker health and aligns with green production standards. Multiple torches can operate simultaneously, producing strong, smooth welds with no oxidation. It meets the precision requirements for refrigeration copper tube welding and the high-demand standards for motor lead welding. The control panel is simple to use and requires no special training. Overall, this welder improves workshop safety, lowers costs, and increases efficiency, making it an ideal choice for refrigeration and motor industry applications.
