Regular maintenance is vital to welder long term and stable operation. After the welder came into use, regular maintenance should be applied. The solid state H.F welder adopts three phase controllable rectifying, achieves DC electric, then through inverter unit to get H.F AC electric, and through capacitor resonance to produce large current. Without proper maintenance, it is easy to cause person and equipment accident. With good maintenance can extend the life span of the welder. So, staff need to learn how to use and maintain the welder properly.
Besides the working voltage of the complete appliance is low, tank capacitance of the all-transistor solid state HF induction welder resonances directly with the induction coil welded on the steel tube, so the efficiency is high. That would demand the operator to have specific general electrical knowledge. And the operator should have the habit of maintaining and safeguarding the equipment. That will assure the normal operation of the equipment. Keep the equipment in the good situation, save a large quantity of electrical energy, and can bring a high output, good quality and economic benefit. On the contrary, the incorrect employment can cause a subpar functional mode of the equipment; appear an unnecessary malfunction or even an outage. Sometimes cause the electrical element to be damaged. That would influence the output and the quality of the equipment, make economic loses. So, we demand safeguarding and maintaining periodically the equipment, extend effectively the useful time of the element to guarantee the normal operation of manufacture.
Organization and plan of maintenance
Maintenance should have progressively the organization and maintenance. Depending on the different situation, the parts of the equipment should be maintained shift, weekly, monthly, semi-yearly, etc. Pay more attention to the parts which are easy to make troubles, such as AC contactor, Medium relay contactor is easy to burn out to cause bad contact. Vibration at work, nut is easy to loose and poor contact, which needs the regular inspection. It's very important to the equipment maintenance that we collect the original record of the technical data. The collection of the data can make the staff comprehend abundantly every fields and periods of the equipment. Grasp the operation rule of the equipment to make them run well. Provide the dependable basis for the economic technical check.
• Keep good contact on the interface of the output plate and its holder.
• Keep good contact on the interface of the holder and the induction coil.
• Induction coil needs an insulating treatment.
• While taking over to the next shift, the staff must do cleaning to the equipment before handing over.
• The overtaker must inspect if there is any flexibility on every interfaces before his starting machine, clean the interface of housing pin, then inspect if there is any water-clock phenomenon on every water way. If we confirm that all is in the normal situation, then start the machine.
• The mechanical adjustment of the forming section must be in the right place. Don't produce any burr into induction coil.
• While starting the machine, open the device of attracting water vapor and iron dust. (We suggest the user to install the device. That would be helpful to keep the device in the good functional mode in the long term, and keep the workshop in good surroundings).
