Specification:Model 110V Input voltage 110V 50/60HzInput current 7AOutput power 500-900WOutput voltage 45VOutput current 180ATool Safety:1. Before plugging in the heating, make sure that the outlet voltage supplied is compatible with the voltage marked on the label and within 10% of the stated voltage. An outlet voltage incompatible with that specified on the label can result in serious hazards and damage to the heating.2. Ensure attachment is securely located. Coil and main are firmly tightened before use.3. Do not use the heating for longer than the stated duty cycle: 5 minutes on followed by 5 minutes off. The main circuit board has an overheat protection device, however the attachments do not have overheat protection so should not be used for more than 5 minutes of continued use.4. Please ensure that the cooling fan is running when the power switch is operated, if the fan does not run DO NOT use the heating and contact us.5. Do not attempt to create more than 4 coils when using the flexible soft coil, a minimum of 2 coils and a maximum 3 to 4 coils is the optimum number needed for best operation.6. Do not leave the coil plugged into the HBR mains when not in use.7. Do not attempt to repair the HBR by yourselves. Please contact us. Operation1. To prolong your heating, leaving an 10mm air gap between the coil and the work piece is recommended as the insulation of the coil will eventually burn through if held directly to hot material.2. Choose the appropriately sized coil to give the closest fit to the work piece.3. Insert both ends of the coil into the coil location socket and tighten the thumb screws securely.Products shipped by US warehouse
