1100W Electromagnetic Induction-Heater High Temperature Handheld Heating Device for Remove Rust Bolt Screws

Features:
The machine perfectly applies electromagnetic induction technology, quickly heating the screw-locked nut to loosening it, which can be used on small parts of automobiles, machinery, various metal parts and polyethylene.
With soft-start function, with long service life, practical and reliable, under frequent starts.
With IGBT overcurrent-protection function.
With input and output overcurrent-protection, automatic adjustment negative feedback function.
With IGBT over-temperature-protection function.
With heating coil short-circuit-protection function.
With heating coil open-circuit-protection function.
Full-bridge series resonance circuit topology, with strong anti-interference ability.
Adopts high-performance IGBT driver chip to drive, can precise drive and output waveform.
Automatic load identification and phase lock function, so that the load side can get a higher power factor, and the circuit can be accurately controlled in the weak inductive area and work efficiently.
Several electromagnetic heating controllers are installed in parallel on the same heating tube without interference.
Power saving, and easy installation, it can be connected to induction coils of barrel type and flat plate type, and etc..
