What to do if the welding tongs heat up too quickly, and how to deal with the overheating of the ele

Whether the welding tongs are hot or not depends on three aspects according to the heat source. One. The conduction heat is mainly the radiant heat of the arc (6000 degrees - 7000 degrees), and the melted electrode core (1535 degrees - 3000 degrees) is the more copper heats up, the more it is easy to burn your hands.

Moreover, the copper material is soft and has poor wear resistance, and the blessing time will not be long, and it will loosen, which is more likely to cause click and resistance heat. (So some iron welding tongs are also applied) two. The wiring method and material at the connection between the wire and the welding tong will promote the connection failure, that is, the phenomenon of heat loosening, which is mainly reflected in the different expansion coefficients of the iron jack wire and the copper core.

Three. It is also unavoidable that it can only be weakened is the resistance heat, as long as the conductor current passes through, the resistance heat can not be completely avoided, there is a skin phenomenon, weakening the skin phenomenon is an effective means to reduce the resistance heat. The main purpose of the welding tong is to select the material properly, not only to ensure the conductivity, but also to refer to the material wear resistance and softening temperature, and then the thermal insulation of the insulating part.

In terms of design, the heating part can also be moved forward as much as possible, avoiding being directly under the handlebar. At present, the better ones are tens of thousands of brand welding tongs and Guangzhou Golden Elephant welding tongs.

It is generally caused by poor contact between the welding wire and the welding tong, or the cross-sectional area of the wire diameter of the welding wire is not large enough.

1) Check if the connection with the wire is not in good contact.

2) If you use high-current welding for a long time, replace it with a large welding tong.

First of all, you have to tell me what welding tongs are. If you have cooling water, check the cooling system. Without a cooling system, it depends on whether the power setting of the welding tong is overloaded.

Otherwise, just buy one that isn't hot.

1. The power supply voltage is too high. Use a voltmeter to check the voltage value of the power supply and compare it with the specified value on the nameplate of the welder.

2. The welding machine is overloaded. According to the specified load rate welding current, use an electric welding machine.

3. Short circuit of the coil of the electric welding machine. The coil should be inspected and repaired.

4. The iron core silicon cavity of the electric welding machine is short-circuited. The silicon steel sheet should be cleaned, and then the insulating paint should be rebrushed to open the cracks.

5. The insulation of the core clamping screw and clamp of the transformer of the welding machine is damaged. The insulation should be replaced.

The solder wire is too thin. Too long.

Solder wire. And.

The welding handle is not in good contact and the screws are not fixed tightly.

The quality of the solder handle is poor, or the heat resistance of the solder handle is reduced after prolonged use.

The main reason. The welding current is large.

Try replacing it with a new one. It must be larger than the current amperage of the welding handle.

No, change the line again.
