Anonymous users2024-02-05How many kilowatts is the general 315 welding machineThe 315 welding machine is.
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 provide the energy and movement needed to complete the welding process, including wire and torch movement and control system equipment.
The 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 electrodes in the event of an instantaneous short circuit is used to melt the solder on the electrode to make them atomically bonded.
Inductance, also known as self-inductance coefficient, is a physical quantity that expresses the self-inductance ability of an inductor. When the magnetic flux passing through one coil changes, an electric potential is generated in the coil, which is a phenomenon of electromagnetic induction. The resulting electric potential is called the induced potential, and the magnitude of the electric potential is proportional to the speed of the magnetic flux change and the number of turns of the coil.
Capacitance, also known as capacitance, refers to the amount of charge stored at a given potential difference.

Anonymous users2024-02-04Power is equal to voltage multiplied by current, divided by 85% power factor is sufficient. The no-load voltage of the inverter welding machine is 70 volts, and the voltage during welding is about 30 volts; Multiply by 30 volts. For example, the power of the welding machine ZX7 series 400A multiplied by 30V divided by 85% = kilowatts, and the load factor should also be considered, which generally does not exceed 50%.

Anonymous users2024-02-02The standard current is about 12kw. Electronic board: It is understood as an inverter welding machine, but there is still no model, so we can only take the most commonly used ZX7-315 as an example, ZX7-315:
Inverter DC hand arc welding machine, the following are its basic parameters: rated output current: 315A; Rated output voltage:
Rated output power: ; Rated input power: approx; And note that most of the input of this welding machine uses 3-phase 380V power supply as input.
The standard is 12kw, but many of the power on the market are only 8 9kw.

Anonymous users2024-02-01Welding machines are divided into single-phase and three-phase.
Except for special needs, all three-phase 380VThe wiring part of the three live wires is suitable for DC inverter welding machine, three-phase power supply capacity is balanced, energy-saving and electric sail.
Single-phase is divided into single-phase 220V and single-phase 380VIt is used for BX series AC welding machine, butt welding machine, etc. High power consumption.
Single-phase 220 is connected to a live wire and a neutral wire. Regardless of the situation. It is used for BX-200 and below AC hand arc welding. Wiring according to the post prompts.
Single-phase 380V is connected to two live wires, regardless of the situation. It can be used for BX-200 and above welding machines, and wiring according to the prompts of the binding post. It can be used for AC BX-200 or above AC hand arc welding, butt welding machine, spot welding machine, etc.
The BX-200 welding machine can be connected to single-phase 220V and single-phase 380V, and the non-state code should be connected to the wrong one. All BX-250 and above are single-phase 380V (two live wires).

Anonymous users2024-01-31Summary. When the power supply is 380 volts, the apparent power that can be carried by the three-wire 4 square copper wire is: 30 * 380 * volt ampere, nearly 20 thousand volt ampere!
How many watts is a 3-phase welder?
When the power supply is 380 volts, the apparent power that can be carried by the three-wire Mengkai 4 square copper wire is 30*380*volt-ampere, nearly 20 thousand volt ampere! Branches.
This is the apparent power that can be carried sustainably.
The power factor of the welding machine is estimated according to the duty cycle, and the power of the welding machine that can be carried by the line is:
20* kW.
Check the wire ampacity meter and know that no matter what kind of structure the three wires are, and no matter what kind of laying method, the current carrying capacity of 4 square copper wires is not less than 30 amperes.

Anonymous users2024-01-30The welding machine is generally 10kw-50kw.
The power of the welding machine is commonly 10kw-50kw, but in fact, the output power of different brands and models of the welding machine is different, and the power of the welding machine is different in different gears, so the power depends on the actual situation. Welding machines can be divided into two types according to the type of output power supply, which are AC power supply and DC power supply.
The welding machine should be placed in a dry, insulated, and sun-proof location, and if it is an open-air operation, it should be placed in a rain-proof, moisture-proof, and sun-proof shed to prevent rainwater from entering and causing leakage of the welding machine.
The basic operation method of electric welding:
1. Linear transport method.
When this method of transportation is adopted, the welding rod does not swing horizontally, but moves in a straight line along the welding direction. It is commonly used for butt flat welding of grooves, first layer welding of multi-layer welding or multi-layer multi-pass welding.
2. Straight-line reciprocating method.
When welding with this strip method, the end of the electrode swings back and forth along the longitudinal direction of the weld. Its special points are fast welding, narrow welds, and fast heat dissipation. It is suitable for the first layer of multi-layer welding with large gaps between thin plates and joints.
3. Zigzag transport strip town front method.
When welding with this strip bright dust method, the end of the electrode makes a zigzag shape and moves forward continuously, and stops on both sides for a while. The purpose of the oscillation is to control the flow of the molten metal and obtain the necessary weld width to obtain a better weld formation. <>

The size of the gear of the mechanical thermostat indicates the temperature level, but it is not possible to determine how many degrees the temperature is because it is greatly affected by the ambient temperature. The smaller the number, the higher the temperature, the larger the number, the lower the temperature, but the user should adjust the digital gear size of the thermostat according to the seasonal ambient temperature, the summer should be adjusted at the smaller digital gear, the spring and autumn should be adjusted at the middle gear, and the winter should be adjusted at the larger digital gear, keeping the temperature of the freezer at about minus 18, the refrigerator between 1-10 degrees, and the best control between 4-8 degrees. It is recommended to put a thermometer in the refrigerator for actual measurement, if the temperature is high, adjust the digital gear a little higher; If the temperature is on the low side, turn the digital gear lower. >>>More
