Features: Precision electronic control circuit Portable and compact size Metal case Impulse sealing for power-saving Adjustable timer creates perfect seals for varying bag thickness Labor-saving design with long handle Low power consumptUse: 1.The machine without power switch. The AC power cord into the outlet, according to the thickness of the material to be sealed, adjust the heating time. The plastic on the sealing surface, then press the handle, the circuit is automatically controlled heating time. When the light is off, the power is automatically disconnected. After about 1-2 seconds, release the handle on a good seal. 2.The square when an access point appears damaged seal, it is because the heating time is too long, please dial anti-clockwise rotation to shorten the heating time. 3.If the seal is not strong, it is because the heating time is too short. Keep the knob clockwise to extend the heating time. 4.If a plastic bag stuck to the rubber plate, indicating the cooling time is not enough, we must extend the cooling time after the light goes out. Please release handle a little bit late. 5.Adjust heating time later, in use should remain unchanged, in continuous use do not have to make any adjustments. 6.The machine can always plug the AC power cord into the power outlet, do not consume power when not sealed.
