How to solve the noise of micro-motor commutator welding machine

An abnormal condition of the AC contactor was found during the welding of the micromotor commutator welder. what is the problem? The following micro motor commutator welding machine manufacturer Hao Jing provides a brief introduction for you. In general, this noise anomaly should not be a great achievement. You can reflect on the four items above in order, and you can return to normal. Investigate whether the AC contact line voltage is lower than 300 volts of its own release voltage during welding. Introspection may be too long and too long, and the line voltage drops too much. The self-test may be too low for the network voltage to work properly. Investigate whether the main transformer is shorted and the current is too high. In addition, when using a micro-motor commutator welder to stop welding, you should also pay attention to a few precautions for ordinary welding: When welding, you should first adjust the position of the electrode rod so that the electrode arm is pressed against the electricity.

Hao Jing spot welding machine forum: five major maintenance methods of lithium battery automatic spot welding machine

(1) Cooling: Because welding water is needed during welding, the water is used to cool the electrodes, secondary circuits, transformers, thyristors, rectifiers and other power components to keep the battery automatic spot welder from high temperature , Can be used normally. Therefore, it is often necessary to check whether the waterways of each branch are unobstructed and clear the blocked waterways in time. (2) Spot welding electrode: The electrode is the part that directly acts on the workpiece during spot welding. It has good conductivity, hardness and high softening temperature, but it will still inevitably deform under continuous high pressure impact and high temperature. Therefore, it is necessary to timely modify the thickness and cleanliness of the electrode end according to the actual welding parameters and the number of welding points, or replace the electrode directly in time. (3) The ground wire must be connected well: In order to ensure the safe use of the battery automatic spot welding machine, it must be used

About Three Structural Features of Welding Equipment System of Vertical Intermediate Frequency Spot Welder

The vertical intermediate frequency spot welding machine system consists of three parts: mechanical device, power supply device and control device. 1. Vertical intermediate frequency spot welding machine In order to meet the requirements of the welding process, the pressurizing mechanism (welding tongs) uses a dual-stroke fast air pressure transmission mechanism. The opening degree of the welding tongs can be changed by switching the stroke control handle, which can be divided into wide open and small open Meet the requirements of welding operations. The general state is that the welding clamp is short-stroke open. When the control button is switched to the energized position, the welding clamp is clamped and pressed when the handle switch is pulled. At the same time, the current returns to the short-stroke open state after completing a welding cycle under the control of the control system . 2. The main power circuit of the power supply device consists of a resistance welding transformer, a thyristor unit, a main power switch, and a welding circuit.

Classification and composition of seam welding machine

Classification and composition of seam welding machine

Introduction: Liu Liu, a small editor of Hao Jing's other spot welders, has already spoken a lot, but the relevant knowledge of seam welding machines has not been told, so today Liu Liu will share a knowledge of seam welding machines for everyone. I hope that I can provide some understanding to friends who need it. Seam welding machine is a resistance welding machine that is assembled with lap joints or butt joints and placed between two roller electrodes. The roller electrodes pressurize the weldment and rotate, continuously or intermittently pulsed power, to form a continuous weld. . It can also be said that the seam welding machine is an evolution of spot welding. Seam welding is widely used in the manufacture of joints that require tightness. Sometimes it is also used to weld common non-hermetic sheet metal parts. The thickness of the metal material to be welded is usually 0.1 ~ 2.5mm. Seam welding machine is the workpiece placed between the roller electrode or the roller electrode and

Do you know how to prevent electric shock when using spot welders?

The welding tongs of the spot welding machine must be reliable. It is forbidden to use the welding tongs without a shell to prevent accidents. The case of the spot welder must be grounded. The purpose of grounding is to prevent the spot welder from accidentally hitting the shell and injuring people from being charged. It is indispensable under any circumstances. Spot welding machine grounding bodies can widely use natural grounding electrodes, such as tap water pipes, metal structures of buildings that are reliably connected to the earth, etc. However, it must be prohibited to use flammable and explosive materials as natural grounding pipes. If the resistance of the natural earth electrode exceeds 4, it is better to choose an artificial grounding body. Otherwise, it may cause an electric shock or even a fire. If it is necessary to move the spot welder, it is necessary to block the power supply. It is not allowed to move the spot welder by delaying the cable. If you encounter a sudden power outage, you should immediately block the power supply in case you suddenly come

Do you know how to judge the welding performance of inverter spot welding machine?

The process parameters of the inverter spot welding machine mainly include welding current IW, welding time tW, electrode force FW, and electrode working surface size. They are closely related and can be varied over a wide range to control the quality of the solder joints. Welding current is the main factor affecting the heat evolution. The heat evolution is directly proportional to the square of the current. As the welding current increases, the size of the nugget or the penetration rate A increases. Under normal circumstances, the current density of the welding zone should have a reasonable upper and lower limit. Below the lower limit, the heat is too small to form a nugget; above the upper limit, the heating rate is too fast, and spattering will occur, which will cause the quality of the solder joint to decline. When the electrode force increases, the upper limit of the welding current that causes spatter also increases. When the electrode force is given in production, adjust the welding current to make it slightly lower than the spatter.
