If we find that the medium-frequency spot welder is hot when we use it, will we be at a loss as to where to start? If the machine is hot, it will not only fail to weld good products, but also pose a great safety hazard. Let's take a look at what went wrong today. Next, the editor of Huandian will analyze the reasons why the medium-frequency spot welder is hot. I hope that you can deepen your understanding of the medium-frequency spot welder through this article.

Reasons for the high-frequency spot welder to get hot:

1. Check whether the circulating cold water system is normal, whether the chiller is turned on, and whether the water channel is blocked.

2. Check whether the insulation resistance between the electrode seat and the machine body is poor, causing a local short circuit. The negligence of this small problem may cause the voltage to overheat.

3. Check whether the water inlet pressure, water flow, and water supply temperature are appropriate.

4. Check whether the copper soft joint and the electrode arm, the contact surface of the electrode rod and the electrode head are severely oxidized, causing the contact resistance to increase and the heating to be serious.

5. Check whether the cross section of the electrode head is overloaded and heated due to excessive wear.

6. Determine the thickness and specifications of the product to be welded, as well as the current used by the medium-frequency spot welder, to see if the load duration rate exceeds the standard.

The above content is the knowledge related to the reasons why the high-frequency spot welder gets hot, I hope it will be helpful to you.
