After the sale of the HF welding machine created by the company, breakdowns are possible. Therefore, when selling welding equipment, a computercompanies in the Russian Federation must provide after-sales service, including the cause of failure, treatment, maintenance, etc. Liaoning Yufei High-Frequency Equipment Co., Ltd.

Common mistakes made by welders are mainly as follows:
1. The welding machine does not have a welding current output
They cause a problem: there is no voltage at the input of the welding machine; Internal thread cut or cut; Internal coils are burnt out.

Treatment: Make sure spare parts, wire, fusible link and junction box parts upstream of the welding machine are not damaged. Make sure the cord switches and loops on the fusion machine are not damaged. Make sure that the primary and secondary windings are on top of the welding machine (as a rule, burn marks are often visible and there are specific smells when burning). If the windings are burned out, it is advisable to replace them.

2. Low welding current or strong arc striking
Cause of the problem: too low mains voltage; the cross-section of the entrance to the power transmission line is simply too small (high resistance, large current losses); welding cabletoo long and too small a section; in this regard, contamination such as paint is present throughout the part; poor contact between the output cable and the part, weakened current regulator.

What happens if you put the RF filter in the wrong place?

If you put the RF filter in the right place, it will break the antenna, for example, where the radio is attached. As soon as you break the antenna more often, there will be no more distant programs. On the other hand, installing this HF filter in the wrong place will usually break the top several inches of the radio antenna.

Treatment: For quick use, only the mains voltage is restored to maintain the nominal value. Apply current to the appropriate power cable according to the set input current of a left-hand welding machine of sufficient cross-section. Increase the cross section of the welding cable or shorten the length of the welding cable, usually no more than 15 m. Remove dirt from the weld. Make good contact with the part of the output cable and secure the loose part of the current regulator.

3. The welding machine is overheated, smokes or has lost its taste
Cause of the problem: the solder of the tool is overloaded; the voltage in the network is the same high; Bad wiring. The usual reason was that when welding machines with a voltage of 220V, and therefore 380V, a voltage of 380V is connected, which is mistakenly connected to the 220V input terminal. Short circuit in the coil.

Treatment: avoid overloading and reduce welding current. If you are using a 220V single phase power supply, it must be connected to the 220V input terminal on the welding machine. If you use 380V two-phase power supply against each other, it must be connected to this 380V input terminal of the welding machine. Check the coil to eliminate the momentary signal error.

4. The welding machine is too noisy
Problem: coil short circuit; damaged coil; Vibration of the moving core; loose housing or chassis.

What are the advantages of RF welding and sealing?

Bottom Line: RF welding and sealing sometimes uses strong electromagnetic radiation (radio waves) to excite each of our molecules in different types of polymers, resulting in very localized heating. The great advantage of HF welding is consistent joint quality and fast cooling.

Treatment: Elimination of coil short circuit problem; tighten its unsecured part of the coil; contains a movable iron core and screws; Check the mounting screws to stop the backlash.
