Connect the power supply. When the green light illuminates, this indicates that the machine is in a normal powered-on state. Step 2.Adjust the temperature according to the type and thickness of the bag. （It is recommended that you start sealing tests at a low setting. If the bag cannot be sealed at this setting, increase it appropriately.) Step 3. There is no need to preheat. Simply place the bag flat on the machine and ensure that the opening is smooth and wrinkle-free. - Step 4. Press the plunger at the end of the handle. The green light will turn red and the sealer will begin to operate. When the red light turns green, the sealing process is complete. （When operating the sealing machine at high speed for an extended period of time, reduce the setting appropriately, bearing in mind that the sealing time increases based on the melting degree of the bag seal. Failure to do so may result in excessive heat at the sealing point, causing the bag opening to melt.） ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B00L2N5X38 | | Best Sellers Rank | #1,804 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #3 in Commercial Bag Sealers | | Brand Name | METRONIC | | Color | Blue | | Customer Reviews | 4.3 4.3 out of 5 stars (1,398) 4.3 out of 5 stars | | Item Dimensions L X W X H | 14.17"L x 3.94"W x 4.72"H | | Item Highlight | Manual Bag Sealer, Heavy Duty Impulse Heat Sealer for Plastic Bags, Shrink Wrap Bag (Blue) | | Manufacturer | Jiaro international | | Material | Iron | | Model Number | 751143 | | Number Of Items | 1 | | Operation Mode | Manual | | Part Number | COMINHKPR71022 | | Power Source | Corded Electric | | Unit Count | 1 Count | | Upc | 796762751143 | | Wattage | 400 watts | ## Product Details - **Brand:** METRONIC - **Color:** Blue - **Material:** Iron - **Power Source:** Corded Electric - **Product Dimensions:** 14.17"L x 3.94"W x 4.72"H ## Images ![METRONIC Impulse Sealer 12 Inch, Heat Sealer Machine with Repair Kit - Image 1](https://m.media-amazon.com/images/I/71PzVNjhlPL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: This says it is 12".
