What are the models of welding rods used for:

The equipment used in electric welding is the electric welding machine.

and some of its accessories.

The welding machine selects different power welding machines according to the size of the welding workpiece, such as the small one such as the portable one of the 250 of Weiodin and the world's smallest electric welding machine, the medium-sized one has ZX7315, and the high-power one has ZX7630.

When performing electric welding, the equipment and appliances to be used include welding machines, welding tongs, welding rods, and connecting cables.

and accessories, etc.

1) Welding tongs Welding tongs are used to clamp the welding rod, and its outer shell is made of a lightweight insulator with high temperature resistance.

Fabricate. Welding tongs must have good electrical conductivity.

And the external insulation is required to be good, and the high temperature is not heated for a long time.

There are two commonly used types: 300A and 500A.

The electrified iron box is called the electric control box, and the welding rod is commonly used.

Small welding things and small and large electrodes that require small current are the opposite

The welding machine is a must, and the welding rod and welding tong are a must.

In some cases, it is also necessary to have a special insulation bucket for the welding rod.

There are more specifications and models of welding rods, depending on what kind of electrode is used for welding, and how thick the electrode is used for welding.

There are two categories of AC arc welding machine and DC arc welding machine.

AC arc welding machine, also known as arc welding transformer, is a special transformer, which turns the alternating current of network voltage into low-voltage alternating current suitable for arc welding, which is composed of the main transformer and the required adjustment part and indication device. Among the AC arc welding machines, the most widely used moving iron AC welding machine is currently the moving iron type AC welding machine.

DC welding machine: It is used to convert alternating current into direct current through the rectifier converter for welding. It has the advantages of small size and light weight.

Its structure is relatively complex, and maintenance is difficult. However, its performance can completely replace the AC welding machine and is more widely used. Including special materials and special electrodes, etc. can be welded.

Type of power supply. The electrode can be used on either AC or DC power. Not all DC electrodes can be used on AC power, but AC electrodes are usually able to be used on DC power.

There are two kinds of welding power supply, DC arc welding power supply and AC arc welding power supply, and welding rods are divided into two categories, namely: acid electrodes and alkaline electrodes. Both DC and AC welding power supplies can be used for acid electrodes, and DC arc welding power supplies must be used for alkaline electrodes.

There are two kinds of connection methods: DC forward connection and DC reverse connection, and the bias blowing and swapping method will be significantly improved during the welding process. In general, the AC welding power supply will not produce bias blowing.

The voltage is generally 20 35 volts, and the current depends on the thickness of the welding material, the size of the welding rod, and the welding structure, and the range is 15 400 amperes.
