The continuous working time of a welding machine depends on its design, heat dissipation performance and the working environment. Generally speaking, most welding machines are not recommended to work continuously for a long period of time, because prolonged working time will cause the internal temperature of the welding machine to rise, which will affect the performance and life of the welding machine. It is recommended to make reasonable arrangements according to the manual of the welder or the actual situation to avoid overuse.

Adjusting the welding current of the welder is usually done by turning the current adjustment knob or button on the welder. The specific adjustment method may vary depending on the model and brand of the welder, so it is recommended to refer to the instruction manual of the welder for operation. When adjusting, the appropriate current level should be selected according to the type and thickness of the material to be welded and the desired welding effect.

The buzzing sound when the welder is working is usually caused by the vibration of the core of the internal transformer or inductor coil. This sound is normal within the normal operating range, but if the sound is abnormally loud or accompanied by other noises, the internal components may be loose, damaged or poorly designed, and it is recommended to check and repair.

When the welding machine malfunctions, first of all, you should cut off the power immediately to prevent the accident from expanding. Then, conduct a preliminary check according to the fault phenomenon and the troubleshooting guide in the manual. If the problem cannot be solved, it is recommended to contact professional maintenance personnel for repair or replacement of damaged parts. Do not disassemble or repair the welder privately to avoid causing greater damage or safety hazards.

The welding machine can weld a variety of metal materials, including iron, steel, aluminum, copper and so on. The welding of different materials requires the selection of appropriate welding methods and welding materials to ensure welding quality and strength. During the welding process, it is also necessary to adjust the welding parameters, such as welding current, voltage, welding speed, etc., according to the characteristics of the material and welding requirement

Care and maintenance of the welding machine is the key to ensure its normal operation and extend its service life. Firstly, clean the dust and debris inside the welder regularly to maintain good heat dissipation. Secondly, check whether the wiring of the welder is firm and reliable, to avoid poor contact triggering failure. At the same time, also regularly check the insulation performance of the welder to ensure safe use. In addition, when the welder is not used for a long time, it should be stored in a dry and ventilated place, and cut off the power supply to prevent damage.

There may be many reasons why the welder does not weld firmly, such as welding current is too small, welding speed is too fast, there is oil or oxide on the surface of the welding material, and the welded joints are not reasonably designed. To solve these problems need to be adjusted according to the specific situation, such as increasing the welding current, reducing the welding speed, cleaning the surface of the welding material, optimizing the design of the welded joints and so on.

When using a welding machine, you must strictly follow the safety regulations. First, make sure the welder is well grounded to prevent electric shock. Second, wear good protective equipment, such as welding mask, protective clothing, gloves and so on. At the same time, pay attention to the ventilation of the workplace to avoid harmful gases and fumes on the human body. In addition, it is also necessary to avoid welding machine overload operation for a long time, in order to prevent overheating caused by fire and other accidents.
