Key FeaturesSturdy and Durable: The product is made of polymerase, 304 stainless steel, sheet metal.Professional Cooling: A self-heating vortex pump, a copper condenser tube, a water circulation system, and a unique wind-tunnel-type heat dissipation design provide this item with a long pump head (98.42-114.82ft), and high heat dissipation (1.5KW), achieving rapid heat dissipation.Thoughtful Design: The thickened eco copper 3771 and PPS water tank has a large capacity of 304.36oz, high hardness, and high-temperature resistance, providing high-quality and sufficient water storage space without leakage. The waterproof switch ensures safe use and extends the lifespan of the machine. High-quality circuit boards can accurately control the smooth operation of the machine.Scientific Working Principle: The water in the tank is introduced by the vortex pump and sent to the cooling channel inside the welding machine through the pipeline, thereby absorbing the heat generated by the welding machine and lowering the temperature. The cooled water is then returned to the tank to continue circulation.SpecificationsModel: WRC-300AMaterial: Polygraphite, 304 Stainless Steel, Eco-friendly Copper, R57Copper, Sheet Metal, Plastic, PPSPump Power: 370WSupply Voltage: 110V / 60Hz Phase Number: Single PhaseHeat Dissipation: 1.5 KW (1 L/35.19 oz/min)Pump Head: 30-35m/98.42-114.82ftFlow Rate: 8L/270.54oz/minMaximum Pressure / Stroke: 0.35 MPA / 50 Hz Water Tank Capacity: 9L/ 304.36ozOperating Temperature: -20 ° C ~ 60 ° C/-4℉~140℉Power Cord Length: 3.5m/11.48ftEach Water Pipe Length: 1.5m/4.9ftProduct Size:45.6*25.3*32.8cm/17.95*9.96*12.91inchPackage Included1* Cooler 2* Pipes2* Snaps2* Quick Connectors1* Manual
