Is it really a problem with the fully automatic collision welding machine that the workpiece is not firmly welded? The common problems during welding with a touch welding machine include incomplete melting of the weld points and splashing during welding, which can cause the fully automatic touch welding machine to not weld firmly. Therefore, in practical use, the following points should be noted:

1. Check if the insulation resistance between the electrode holder and the body of the collision welding machine is poor, causing a local short circuit.

2. Check if the water inlet pressure, water flow rate, and water supply temperature of the welding machine are suitable, and if there are any blockages caused by dirt in the system, resulting in overheating of electrode arms due to poor cooling.

3. Check if the contact surface between the copper soft joint and electrode head of the collision welding machine is severely oxidized, causing an increase in contact resistance and severe heating.

4. Check whether the welding thickness and load duration of the collision welding machine meet the standards, so that the collision welding machine can overheat due to overload.

2、 Improper splashing occurs during welding with a touch welding machine:

1. Check if the current of the welding machine is too high or the pressure is too low.

2. Insufficient strength of the workpiece welded by the collision welding machine: When welding with the collision welding machine, the current becomes smaller and smaller, resulting in weak welding.

3、 The welding points of the welding machine are not fully melted, and the formation of fusion nuclei is poor or not formed:

1. Not fully melted refers to the absence of a "bean like" fusion zone during the welding process of the welding machine. This defect is very dangerous as it greatly reduces the strength of the solder joint.

2. Debug the welding parameters of the touch welding machine. If the parameters have been confirmed to be correct, it is necessary to check the main power supply circuit, such as whether the power supply is sufficient, whether the welding machine and transformer are damaged, etc.
