Correct use and daily maintenance of spot welding equipment for small circuit breakers

The correct use and daily maintenance of spot welding equipment for small circuit breakers are very important to ensure equipment performance, prolong service life and ensure production safety. The following is a detailed explanation of both aspects:

First, the correct use of small circuit breaker spot welding equipment

Adjust welding parameters: According to the needs of different welding materials and thickness, adjust the current, voltage and pressure parameters to achieve welding results. Especially when the thickness of the welded metal material is thin, the welding time should be appropriately reduced and the current should be strengthened to ensure the uniformity and welding quality of the welding points.

Adjusting electrode position: Before welding, the position of the electrode rod should be adjusted so that the electrode arms remain parallel to each other when the electrode is just pressed to the weldment. At the same time, ensure that the contact between the electrode and the weldment is good to obtain a stable welding effect.

Preparation of welds: welds should be cleaned before welding all dirt, oil, oxide and rust. For hot-rolled steel, the weld is first pickled, sandblasted or the oxide is removed with a grinding wheel. Although uncleaned welds can be spot-welded, they will seriously reduce the service life of electrodes and the production efficiency and quality of spot welding.

Operation sequence: After completing the above adjustment, first turn on the cooling water, and then turn on the power to prepare for welding. When welding, place the weldment between the two electrodes, and press the foot pedal to make the upper electrode contact and pressure the weldment. When the pedal is pressed down, the power contact switch is switched on, the transformer begins to work, and the secondary circuit is energized to heat the weldment. When the pedal is released after welding for a certain time, the electrode rises and first cuts off the power supply and then recovers, and the single-point welding process ends.

Second, small circuit breaker spot welding equipment daily maintenance and cleaning

Regular cleaning: regularly clean the oxide, dust and other dirt on the surface of the electrode to ensure a good contact state of the electrode. Special cleaning agents or alcohol can be used when cleaning, but should avoid using too rough cleaning tools, so as not to damage the electrode surface.

Check the electrode status: regularly check the wear of the electrode, such as serious electrode wear or surface cracks and other defects, should be replaced in time. At the same time, check the fastening of the electrode to ensure that the connection between the electrode and the equipment is firm and reliable.

Check power cables and electrode lines: regularly check the power cables, electrode lines and other machine lines of the spot welding machine to ensure that the lines are not aging, wear or damage. If any problem is found, it should be replaced or repaired in time to avoid equipment damage or safety accidents caused by line faults.

Lubricate the transmission part: For the spot welder with the operating mechanism, the transmission part should be lubricated regularly. When lubricating, special lubricating oil suitable for electrical equipment should be selected, and be careful not to drip lubricating oil into the equipment to cause damage.

Check the cooling system: Check the operating status of the cooling system regularly to ensure that the cooling water is unimpeded and the water quality is clean. If the cooling water is cloudy or blocked, the cooling system should be replaced or cleaned in time.

Properly configure the production process: if there are multiple spot welders in production, the production process of each machine should be reasonably configured, and the welding load should be evenly distributed to each spot welder, so as to avoid the situation of excessive welding of a spot welder and idle of other spot welders, so as to improve the service life and production efficiency of the welding machine.

In summary, the correct use and daily maintenance of spot welding equipment is an important link to ensure equipment performance and production safety. By following the above recommendations, you can ensure the stable operation of the equipment and extend its service life.
