Ling Rui is only available on a certain website, and registered in Hong Kong. It's hard to say whether it's genuine or not.
Ling Rui Vulcan is a welding machine series owned by Shenzhen Ling Rui Welding Machine, which belongs to Ling Rui brand.
Ling Rui Vulcan, the main household field, uses mos field effect transistors, so its service life is not very long, the failure rate is relatively high, and the price is relatively cheap.
Extended data:
When buying electric welding machine, it should be noted that
1. Reasonable welding process (covered electrode, welding current and temporary load rate) should be selected according to the technical conditions of the workpiece, and overload use is not allowed, and no-load power-off device should be adopted as far as possible. High current welding is not allowed, and metal cutting with electric welding machine is not allowed.
2. During load welding, the temperature rise of the welding machine shall not exceed Grade A 60C and Grade B 80C, otherwise, the welding machine shall be stopped and cooled before welding.
3, welding machine work site should be kept dry and well ventilated. When moving the welder, cut off the power supply and do not drag the cable to move the welder. If the power supply is suddenly cut off during welding, please cut off the power supply.
4, when welding, are not allowed to adjust the current, must use the handle to adjust the welder current to stop welding, not too fast and too hard, so as not to damage the regulator.
5. When the DC welding machine is started, check whether the rotating direction of the rotor is consistent with the arrow marked by the welding machine.
6. The gap between the edge of the carbon brush holder of 6.DC welding machine and the commutator surface should not be less than 2-3mm, and pay attention to regular adjustment and cleaning of dirt.
7. When using the silicon rectifier welding machine, you must first turn on the fan motor, and the indicated value of the voltmeter should be normal. Listen carefully and there should be no sound. Clean the silicon rectifier and other components after shutdown.
8. It is forbidden to test the secondary coil of the main transformer and the secondary coil of the control transformer of the silicon rectifier welding machine with a shaking table.
9. When welding must be carried out in a damp place, the welder should stand on the insulated wooden board, and it is forbidden to touch the welding wire with his hand and clamp the electrode holder with his arm to avoid electric shock.
During the use of electric welding machine, a certain magnetic field will be generated around the welding machine, and radiation will be generated when the arc burns. There are harmful substances such as infrared rays and ultraviolet rays in the arc, as well as metal vapor and smoke, so adequate protective measures must be taken during operation. Welding is not suitable for welding high carbon steel. Due to the crystallization, segregation and oxidation of weld metal, the weldability of high carbon steel is poor, and it is easy to crack after welding, resulting in hot cracks and cold cracks.
Low-carbon steel has good weldability, but it needs proper operation in process and complicated rust removal and cleaning. Defects such as slag inclusion crack, blowhole and undercut sometimes appear in the weld, but proper operation will reduce the occurrence of defects.
