1. Quality requirements for the machine
Regarding the quality of the machine, that is, during use, whether the machine often fails and whether the parts are often damaged. If you buy a machine of poor quality, then the frequency of repairs will also be very high. Therefore, for the quality of the machine, everyone must polish their eyes when purchasing, and the important assembly accessories of the machine must be a quality assured brand, and cannot choose inferior miscellaneous brands. When buying a machine, do not only greed for cheap, cheap machines, manufacturers in the production cost will definitely try to reduce the cost, so that for the purchase of accessories, manufacturers may choose inferior accessories.
2. According to production demand
If the production volume is large, you can choose an automated machine to weld, save manpower and material resources, and ensure welding quality. If the production volume is small, you can use the gantry spot welding machine to manually weld it.
3. According to the quality requirements of the welding effect
For technical process requirements of high quality, it is recommended to use transistor power supply spot welding machine, transistor welding power supply is the best welding effect of all power supplies, of course, choose the power supply should also choose a well-known welding brand, because there are many transistor welding power sources on the market, but the quality is different and uneven. For example, some manufacturers introduce transistor power supply, but in fact they are impersonated by other welding power sources, and the phenomenon of selling dog meat with sheep's heads is also common. Or according to our Chinese saying, cheap is not good goods, good goods are not cheap.
Therefore, manufacturers with high requirements for welding quality must buy manufacturers with after-sales guarantees of big brands when choosing power supplies.
4. According to the thickness of the nickel sheet
The thicker the nickel sheet, the greater the welding power required.
Welding 0.02mm-0.18mm thickness nickel sheet, using multi-pulse welding power supply can also achieve welding effect, but if you want to have higher welding quality, you can choose to use transistor 5000A welding power supply. More than 0.18mm need to choose transistor 8000A / 10000A welding power supply, choose other welding power supply may have welding instability, virtual welding explosion welding and other undesirable phenomena. It needs to be emphasized here that no matter how much welding power is, nickel sheets exceeding 0.2mm need to be grooved to ensure perfect welding.
5. After-sales service of the machine
In terms of equipment, there will be large and small after-sales problems, such as incorrect parameter adjustment, inability to weld, and damage to wearing parts after the equipment has been used for a long time. These after-sales problems need to be solved by manufacturers, so after-sales service is crucial. To confirm the repair deadline of the machine, the repair deadline of important components should also be confirmed for large automation equipment. Choose a powerful large manufacturer, because small manufacturers may go bankrupt after a few years, then it will lead to a lot of after-sales problems, and no one will help you solve them. Another important point is to know whether the on-site maintenance is charged, and how much is the one-time charge, because some of our customers have told us that the machines they have purchased before are charged a large amount of money for on-site maintenance.
