Copper Pipe Welding Heating Machine with Water Pump and Handle,High Frequency Induction Heater for Melting Metals,Quenching Annealing,Alloy Welding,Laboratory Material Heating 3000W

selectable based on heating requirements:Low power (2000W): Jewelry melting, small workpiece welding.High power (3000-6000W): Large part hardening, batch welding, metal melting.*Accessory FunctionsWater pump: Provides circulating water cooling for the coil and main unit, preventing damage from overheating.Water basin / Stainless steel bucket: Stores cooling water, forming a closed-loop cooling system.Crucible set: Graphite/quartz crucible for holding metals to be melted.Foot switch: Controls heating start/stop, freeing both hands, suitable for welding, melting operations.Copper coil: Standard heating coil, ready for immediate use.*Core ApplicationsJewelry making (gold/silver melting, welding).Hardware processing (small workpiece hardening, welding).Laboratory research (metal material experiments, melting).Small workshops/factories (heat treatment, brazing).*1. Up/Down: Adjusts output power, heating time.2. Load Detection / Energy Saving: only when a heating object is present, automatically stops when absent to save energy and prevent no-load operation.3. On/Off: Starts/stops heating.4. Foot switch port: For connecting an external foot switch, enabling semi-automatic control.*Usage Precautions1. Water cooling is mandatory: Always start the water pump before powering on the unit. Ensure water lines are clear. Never without water, as this will burn out the coil and main unit.2. No-load protection: With load detection enabled, heating will not activate without metal present, preventing no-load energy loss.3. Regular maintenance: Periodically replace cooling water, clean coil of impurities, and inspect wire connections.
