Now there are many cold welding machine manufacturers in the market. How to distinguish the quality of cold welding machine is good or bad. Here we have sorted out several key points for your reference.

1. Let's first look at the warranty time of cold welding machines. Now most cold welding machines in the market have poor quality, so the after-sales warranty time is guaranteed according to the national standard for one year. Hongyu cold welding machine is one of the few manufacturers in China with two-year warranty.

2. See whether the cold welding machine manufacturer can conduct on-site training. If it can conduct on-site training, it shows that the manufacturer is more confident in the quality of its cold welding machine, so it can conduct on-site training. Hongyu cold welding machine promises on-site training.

3. See if the after-sales service system of the cold welding machine manufacturer is perfect. If a company doesn't even have a system for how to deal with after-sales quality problems, who dares to buy the company's products.

The above points are my opinions on how to distinguish the quality of cold welding machines. I hope they can be helpful for you to buy cold welding machines. thank you
