Where can I repair an electric welding machine? If the welding machine is broken, where can I fix it

Today's electric welding machines are basically electronic, and there are few AC welding machines. Therefore, it is best to mail the electronic welding machine back to the manufacturer for maintenance.

Generally, there are welding machines in the hardware wholesale market in every city. If you are in the town or the countryside, you can only find a master who repairs electrical appliances to try. Also, don't always worry about those manufacturers, whether your machine is over or not within the warranty period, it will generally take about a week or more to send it back for repair, unless you are not in a hurry to work, otherwise it will be worn to death by the manufacturer's maintenance time.

And the logistics company sometimes loses the shipment or damages the package. We are in Building 10, Yard 136, Chengshousi Road, Beijing, and Youshi Welding specializes in repairing all kinds of electric welding machines. Hope it helps.

1. Repair method:

It is to reduce the welding current used, eliminate the phenomenon of short circuit, and restore the insulation.

It is to make good contact between the welding cable and the weldment, and try to prevent the movement of the movable core.

It is to tighten the screws, adjust the broach of the spring, and check and repair the moving mechanism.

It is to check and eliminate the shell collision, eliminate the phenomenon of touching the shell, and connect the grounding wire.

It is to shorten the length of the cable or increase the diameter of the cable, release the cable and not make it into a disc shape, so that the joint is in good contact.

Second, a brief introduction of the welding machine:

The purpose of the electric welding machine is to use the high-temperature arc generated by the positive and negative electrodes in an instantaneous short circuit to melt the solder and the welded material on the electrode, so that the contact object is combined. Its structure is very simple, it is a high-power transformer. Welding machines can generally be divided into two types according to the type of output power supply, one is AC power supply and the other is direct current.

They use the principle of inductance, the amount of inductance will produce a huge voltage change when it is turned on and off, and the high-voltage arc generated by the positive and negative poles in the instantaneous short circuit is used to melt the solder on the electrode to make them achieve the purpose of atomic bonding.

There are still many places to repair the welding machine, you can go to the nearest maintenance office, and some mechanical and electrical maintenance places can repair the welding machine!

Generally, the place where the motor is repaired can be repaired, but most of the current electric welding machines are electronically controlled, and there are many integrated block templates, so it is best to find the original manufacturer for maintenance.

In Taiyuan Wanshui Trade City South Inner District No. 3 professional repair welding machine hope to help you.

Hello dear, 1. Maintenance of electric welding machine (1) The use of electric welding machine should establish a strict management and use system. (2) The welding machine should be kept clean frequently, and the internal dust should be blown off with dry compressed air regularly. (3) The welding machine should not be used in an overload state.

4) When used in the open air, rainwater should be prevented from invading the inside. (5) When handling, it should not be subjected to severe vibration. (6) In case of failure, the power supply should be cut off immediately and repaired in time.

2. Common faults and troubleshooting of electric welding machine 1The reason for no output failure: the main reason is that the primary coil or the secondary coil has an open circuit.

Exclusion method: Detect the circuit break point by direct observation method or multimeter measurement method, and after finding the circuit break point, fix the connection with welding method or screws, and add pad insulation. 2.

The welding current is too small and the fault causes: the welding cable is too long; The welding cable is coiled into a disc shape, resulting in excessive inductance, and the welding cable is in poor contact with the binding post. Exclusion Method:

Reduce the length of the cable or increase the cross-sectional area of the cable core, straighten the cable as much as possible so that it is not bent, so that the cable is in good contact with the binding post. 3.Causes of live failure of welding machine shell:

The primary or secondary coil touches the shell, the power line touches the shell, the welded cable touches the shell, and the shell is poorly grounded or not grounded. Elimination method: eliminate the phenomenon of hitting the shell, connect the ground wire, and ground the shell well.

4.During the welding process, the movable iron core has a strong vibration sound Fault causes: the brake screw or spring of the movable iron core is loose, and the moving mechanism of the iron core is damaged.
