Mid frequency spot welding machine is a facility that uses Joule heating generated by energized electrodes to instantly melt welded parts, thereby achieving rapid welding of workpieces. Especially for some professional spot welding machines, they not only help to accelerate welding power, but also improve working conditions. However, there are many types of intermediate frequency spot welding machines on the market, which makes many buyers feel at a loss. In fact, when choosing an intermediate frequency spot welding machine, you can refer to the following three aspects:

1. Pressure curve

According to a large amount of market validation data, a cost-effective mid frequency spot welding machine has a good pressure curve. The appropriate pressure level can ensure that the weld nugget cracks are more in line with the standards. Generally speaking, excessive or insufficient pressure can cause the melting point to crack during the formation of weld nuggets, and excessive spot welding pressure may also cause shrinkage. Therefore, choosing a medium frequency spot welding machine can determine whether its pressure curve meets the application standards through small tests.

2. Determine the detailed content of the nameplate

When choosing an intermediate frequency spot welding machine, it is also necessary to carefully check the nameplate content. According to market research results, regular spot welding machines have clear nameplates, which will detail the manufacturer's name, specifications, and adjustable range of welding current. The purchaser can determine the appropriate type of spot welding machine based on the location and workload where the intermediate frequency spot welding machine will be applied.

3. Confirm the certificate of conformity and related product quality inspection reports

When choosing an intermediate frequency spot welding machine, it is also necessary to confirm the certificate of conformity and relevant product quality inspection reports, as these welding products must undergo mandatory national certification. Therefore, the purchaser needs to confirm in advance whether they meet the corresponding certification standards when purchasing. Welding machines that have not passed the certification standards may have safety hazards. It is recommended that the purchaser prioritize using legitimate spot welding machine products with strong brand influence.

Mid frequency spot welding machine is a highly used welding product, so more and more industries are searching and ordering high-quality spot welding machines. In addition to comparing prices and functions, it is also necessary to carefully confirm the pressure curve, detailed nameplate content, certificate of conformity, and related product quality inspection reports when purchasing such welding products.
