① The ultrasonic welding machine cannot be put into use immediately after being powered on. Wait for two minutes before testing the ultrasound and putting it back into use.

② The ultrasonic welding head (upper mold) cannot pass the test identification during testing, please do not continue to use it! Otherwise, burn out valuable components such as amplifiers and transducers!

③ Ensure the compressed gas provided is dry and clean, and regularly check whether the back filter of the ultrasonic welding machine is clean (if there is oil stains, please clean it). Before replacing the ultrasonic welding head (upper mold), the connection position should be checked for oxides (usually black or white substances). If there are, please use 800 grit (or finer) sandpaper to polish it off and wipe it clean with alcohol before installation; During installation, the assembly must be securely fastened without any looseness.

④ Ensure the compressed gas provided is dry and clean, and regularly check whether the back filter of the ultrasonic welding machine is clean (if there is oil stains, please clean it).

⑤ The ultrasonic welding head (upper mold) can pass ultrasonic testing, but there is heating phenomenon during use. No matter how busy it is, it must be stopped from use and allowed to cool naturally before continuing to be used; If there is heat within half an hour to two hours, it must be replaced.

⑥ For plastic parts with non special structures (materials), please adjust the "delay time" to the moment before the ultrasonic welding head (upper mold) contacts the plastic part to start emitting ultrasonic waves. If only the reverse force triggers the ultrasonic system, please adjust the switch to the low power trigger point.

⑦ The power supply range should be within a 5% variation range of 220VAC, and the grounding wire of the metal part of the ultrasonic welding machine shell (usually double grounded) should be used as much as possible with a regulated power supply.

⑧ If you hear abnormal noise when welding plastic parts, please stop working and check whether the ultrasonic welding head (upper mold) amplifier transducer has cracks or good contact with each other. If there are cracks, they need to be replaced; If there is any looseness, please tighten it relatively.

⑨ It is not advisable to hold down the detection button for a long time when detecting the frequency of ultrasonic molds; When adjusting the frequency, do not hold down the test ultrasonic button while adjusting the frequency knob.

⑩ Each ultrasonic welding head (upper mold) needs to adjust its frequency before use. As long as the molds manufactured by oneself are replaced, there is no need to adjust the frequency one by one, only the first mold frequency needs to be adjusted. During the continuous use of the ultrasonic upper mold after adjusting the frequency and determining it, it is strictly prohibited to adjust the frequency.
