Induction Innovations' Mini-Ductor II CE uses high-frequency magnetic fields to generate invisible heat to heat metal objects without an open flame. This helps in the removal or installation of metal hardware or parts without having to use a torch, or worry about melting plastic. The Mini-Ductor II 220V can heat nuts/bolts up to 2” and turn a 3/4" nut red hot in 15 seconds. The "invisible heat" is faster and safer than a torch, yet instantly heats and removes seized nuts/bolts, bearings, and other metal or mechanical hardware without the danger of an open flame or collateral damage. International model is CE certified and carries one year warranty.
