Key Features This semi-automatic glue dispenser machine is equipped with a vacuum back suction device, which can effectively prevent the glue from dripping during use to achieve a more accurate glue dripping, and ensure a clean and tidy working environment. This item adopts a high-quality electronic valve, which can instantly start the diaphragm valve and increase the working efficiency by more than 80%. The minimum drip volume is 0.01ML, and the spitting interval is 0.1-9.9s. It can drip precisely and achieve a repeat accuracy of about 0.5%. It is also equipped with a single-hole hand control switch, allowing you to control it personally by hand for more accuracy and timeliness. It can be both automatically dripped by the machine and precisely controlled by a single-hole hand switch. If you want to free your hands, you can set the switch to the automatic position, to achieve a more efficient and higher-quality working method. Features a high-end all-copper coil transformer, which can stabilize the voltage change and increase the service life, and can be used in high-frequency and high-intensity work scenarios, improving operational safety while being efficient and energy-saving. The high-precision air pressure gauge can precisely control the air pressure input to the air pump and convert the air pressure precisely. Application It is suitable for most of the yellow glue, quick-drying glue, epoxy resin, etc. in the market, and is widely used in bonding various electronic components, machine production, instrumentation, jewelry, and other objects. Specification Color: Black Model: 982 Material: Metal Spitting Mode: Manual / Semi-automatic Minimum Drip Volume: 0.01ml Spitting Time Interval: 0.1-9.9s Automatic Timing(Can Be Set): 0.01-30s Repeat Accuracy: ±0.5% Internal Voltage: 12-24DC Input Air Pressure: 2.5-7bar(35-100psi) Output Air Pressure: 0.1-5.5bar(1-78psi) Power Supply: 220V AC, 50Hz Power Consumption: 20W Plug Specification: European Standard 220V Product Size:23*15*6cm/9.05*5.9*2.36in Package Size:20*26*14cm/10*9*12.5in Gross Weight: 2.1kg/4.63 lbs Package Included 1* Dispenser Main Unit 1* Manually Switch 1* Foot Switch 1* Air Tube 1* Connection Tube 1* Power Cord 1*Dispenser Stand 2* 30CC Liquid Barrels 6* Dispensing Needles 1* Chinese and English Manual   Notes:  1.The input high pressure should not exceed 7 bar (100psi), and the maximum working pressure of the glue dropper should not exceed 5.5 bar (78psi). If the working air pressure is above 4 bar, please switch to aluminum connectors. 2.If available, store all materials at a constant temperature (5°) as directed to ensure that the concentration does not change significantly during use. 3.When the material concentration is too large (flow difficulties), can not drip, if you want to use it, according to the manufacturer's instructions dilute the use; before work, the material must be fully stirred evenly to ensure that the size of the drip consistent. 4.Automatic state, the general air pressure adjustment in the machine at 1-2.7bar (15-40psi) is more appropriate. When working in the automatic state, the strength of the vacuum tube pumping back air should be adjusted to the proper position. 5.Automatic state work, according to the actual situation, timely removal of the material left at the needle nozzle, these materials gradually curing will block the muzzle discharge and back pumping; after work, the barrel should be cleaned in time, otherwise, the barrel's disassembly will be very difficult.
