Is Zx7 500G inverter DC arc welding machine available for electroslag pressure welding

ZX7-500G Inverter DC electrode hand arc welding machine with rated output welding current of 500 amps, (welding current is not false, the standard reaches 500 amperes, and the load rate of the welding machine is 60) can be used for vertical steel bar electroslag pressure butt welding. The welding current cannot be reached or the load rate of the welding machine is low, and it cannot be used.

Electroslag pressure welding of steel bars is a pressure welding method in which two steel bars are placed in a vertical butt form, and the welding current is used to pass through the gap between the two steel bars to form an arc process and an electroslag process under the flux layer, which generates arc heat and resistance heat, melts the steel bar, and is completed under pressure.

The welding process of electroslag pressure welding consists of four stages: arc striking process, arc process, electroslag process and top pressure process.

At the beginning of welding, the arc is first ignited between the end faces of the upper and lower steel bars, so that the flux around the arc melts to form cavities; Subsequently, the welding arc burns between the two steel bars, the arc heat melts the ends of the two steel bars, the molten metal forms a molten pool, and the molten flux forms a slag (slag pool), which is covered on the molten pool. With the continuation of the arc process, the melting amount of the end of the two steel bars increases, the molten pool and the slag pool are deepened, and when a certain depth is reached, the downward feeding speed of the upper steel bar is accelerated, so that the end of the steel bar is directly in contact with the slag pool, at this time, the arc is extinguished and the arc process is changed to an electroslag process; When the resistive heat generated by the electroslag process makes the ends of the upper and lower steel bars reach the full section of uniform heating, the upper steel bar is quickly pressed downward, all the slag and liquid metal are extruded, and the welding power supply is cut off immediately, and the welding work is completed.

Electroslag pressure welding is suitable for the connection of vertical or oblique (inclination within the range of 4:1) steel bars in cast-in-place reinforced concrete structures, especially for column and wall reinforcement of high-rise buildings, which is particularly widely used.

It is possible according to the current, but whether it is feasible or not depends on the actual duty cycle of the equipment. Generally, there is no problem in welding steel bars with small diameters. Therefore, except for the electric welding machines produced by some small manufacturers, others can be used for electroslag pressure welding.

How does ZX7-400T DC welding machine achieve argon arc welding?

Hello Segment Chain, glad to answer for you, <>

The argon arc welding method of DC welding machine is as follows: DC positive polarity connection workpiece is connected to the positive electrode of the power output end, and the welding torch is connected to the negative electrode of the power output end. For ferrous metals (steel), this connection method should be used. At this time, the tungsten electrode can pass through a large welding current, and the arc is in the shape of a thin cone, so that the arc heats the weldment intensively, so as to obtain a deep and narrow weld shape.

2. The DC reverse polarity connection workpiece is connected to the negative electrode of the power supply output end, and the welding torch is connected to the positive electrode of the power supply output end. This connection method is not suitable for welding ferrous metals (steel), and the arc diverges at this time, so a shallow and wide weld is obtained, which is suitable for the welding of aluminum, aluminum alloy and magnesium alloy. The reverse polarity welding technique is not easy to master, and it is easy to burn the tungsten electrode.

Hope the above helps

ZX7-630 inverter DC arc welding machine welding rod can not be opened.

It belongs to the inverter DC electrode hand arc welding machine, and 630 is the rated output current of the welding machine 630 amps. Sell the weld-resistant handle to connect the positive electrode +, and the ground wire to the negative electrode - belongs to the DC reverse connection. With welding arc stability, it is suitable for the welding of various acid electrodes and alkaline electrodes.

Minimal splashing. The penetration depth of chain source welding is shallower than that of power frequency AC welding machine. It is more suitable for the characteristics of all-position welding.

Suitable for carbon arc gouging function. It is a welding method that is usually used. The welding handle is connected to the negative electrode-, and the ground wire is connected to the positive electrode +, which is a DC Zhongchun positive connection.

It has the characteristics of large welding spatter, long arc, fast melting speed and large penetration depth, except for surfacing welding of heat-sensitive metals, cast iron welding, usually less welding.

1.First of all, it is necessary to look at the welding machine, and identify whether it is a single-phase 220V input or a 3-phase 380V input;

2.Generally speaking, the power of ZX7-315 is not small, and it is less likely to use single-phase 220V input;

Let's talk about the reasons why the welding machine with a 3-phase 380V input can't be forced to use a single-phase 220V

Three-phase electricity is 3-phase 380V, single-phase electricity is 1-phase 220V; First of all, the input voltage cannot be reached; Even if you use a 2-phase 380V input--- see the analysis below;

Three-phase power input welding machine, generally the welding machine of each welding machine manufacturer is designed with three-phase electric phase loss protection; (Some even have out-of-phase bias protection!)

The input power of the second welding machine is generally small, even if your welding machine manufacturer has not bothered to design the lack of phase protection and allows two-phase input; If the cross-section of the cable is insufficient or the power of the three-phase home is insufficient, it is easy to pull the three-phase electric into a three-phase unbalance--- which will be very unfavorable to other equipment that uses three-phase electricity, such as the three-phase motor is not stable.

From a professional point of view, the DC ripple after three-phase rectification is much smaller than that after single-phase (two-phase behaves the same as single-phase), which is advantageous for the high-voltage DC filter capacitor in the welding machine; This is the reason why in the second point above, each manufacturer will design the technical layer of phase loss protection;

The operation of this inverter welding machine is very simple, read the manual, wiring and adjusting the current.

1. Small size, light weight, saving materials, easy to carry and move.

2. High efficiency and energy saving, the efficiency can reach 80% 90%, which is more than 1 3 more than the traditional welding machine.

3. Good dynamic characteristics, easy arc starting, stable arc, beautiful weld forming, and small spatter.

4. Combined with robots, it can form an automatic welding production system.

Absolutely.
