In various areas, spot welding is used for do-it-yourself batteries. The characteristics of the devices on the market are different. Modern devices are expensive, and acquiring them is problematic. In order to determine the assembly, you must first familiarize yourself with existing types of devices.
Allocate contact, as well as capacitor modifications. The main parameters of the devices include power, overload, output resistance. Also, modifications are made with the functions of quick start, interruption and protection.
Capacitor welding
Do-it-yourself capacitor spot welding for batteries is done from a dipole coil. Directly the transformer is selected with contact triodes. First of all, an adapter is installed during welding. To close the contacts you will have to use a welding inverter. Many experts recommend not using large capacitors.
The thyristor block is mounted near the holder. Camping resistors are used to close the system. Next, to assemble the device (spot welding for batteries) with your own hands, you will need a tester. When you turn on the device, it is important to pre-measure the resistance at the input contacts. This parameter must be in the range of 30â40 Ohms.
Features of contact welding
Do-it-yourself spot welding for batteries is easy. Many experts recommend the use of high voltage boxes. Resistors can only be installed after the adapter. In this case, the expander unit must withstand a voltage of 300 V. According to experts, the modulator will not be required during assembly. To solve the problem with increased voltage, you can use a simple diode resistor. Relays of many modifications are used for switching type.
The output conductivity parameter averages 5 microns. Further, to make the machine for spot welding of batteries with their own hands, a simple holder with a double adapter is used. A welding inverter is used to connect the regulator. It is also worth noting that experts do not recommend using adapters with comparators. In this case, the overload indicator on the relay will increase significantly.
Modification from the microwave
Do-it-yourself spot welding for batteries from the microwave is quite simple. The first step is to remove the emitter from the model. A transformer for assembly is more appropriate to use at 20 watts. Some experts recommend using a small capacitor unit. It is also worth noting that when assembling it is important to use a zener diode. As a rule, it is selected with a contact type adapter. The output conductivity parameter should be at least 4 microns. Further, to assemble the modification with your own hands, an amplifier with a triode is taken.
To install these elements you will need a conventional welding inverter. However, before soldering the triode, the output resistance at the cathode is checked. This parameter must not exceed 40 ohms. Contactors during assembly are often used semiconductor type. They are very easy to install. Some solder them immediately after the zener diodes.
Assembly instructions for 3-A models
With 3-A, spot welding for batteries with your own hands is going to be quite simple. First of all, a wave transformer is selected. The relay is used only with a rubber lining. Quite often, transceivers are used unipolar type. Their overload indicator should be at least 300 N. Amplifiers in this situation are rarely used for assembly. It is also worth noting that when folding the device with your own hands, you must use a 4 pF capacitor.
Contactors in this case are used with field effect transistors. Finding them in the store is quite problematic. However, these elements can always be replaced by linear analogues. The input resistance parameter does not exceed 44 Ohms. Regulatory boxes for hot start apply diode type. Comparators when collecting modifications to 3-A are not required. At the end of the work, it remains only to fix the holder of the device.
10-A device
At 10-A, spot welding for batteries with their own hands develops only on the basis of a wave transformer. If you believe the experts in this field, then the adapter must be soldered first. High capacitors must not be used. It is also worth noting that many modifications have two triodes. After installing the transceiver, the capacitor box is soldered.
Further, when assembling the device with your own hands, a comparator is installed. Modifications of a single junction species are very rare. Holders are used with and without handles. Triodes are often mounted without zener diodes. It is also worth noting that in our time are more popular modifications with rotary controls.
Home-made device on 15-A
At 15-A, spot welding for batteries with your own hands is done quite simply. For this purpose, the expander is used dipole type. However, the contact adapter is primarily used during assembly. A condenser box is installed behind the expander. It is also worth noting that low-impedance type models are not recommended. After installing the adapter, a transformer is installed.
Next, to make a 15-A device with your own hands, a coil is taken. Quite often it is used with two adapters. To make a coil with your own hands, a small tube is taken. Contactors are mounted on plates. It is more expedient to apply a thyristor for assembling a modification to a regulatory type.
Zener diodes on devices are installed quite rarely. Some experts recommend the use of field effect transistors only. However, they have a very low conductivity index and have problems stabilizing the output current.
Devices with triggers KU 202
With KU 202 triggers, spot welding for batteries with your own hands is done using wave transformers. Before assembling the model, it is important to prepare the coil as well as the expander. Many experts do not recommend the use of cheap small capacitors. Holders should be installed on the device last.
It is also worth noting that after installing the adapter, a stabilizer is taken. It is necessary to solder it near the regulator. To this end, it is necessary to use a welding inverter. Diode transistors in this case are installed quite rarely. Modifications with triodes are also not very popular. Holders are often used with insulators.
Modifications to the DR 101 Series
You can make a modification of this series on the basis of a transceiver or a wave transformer. The power of the device should average 300 watts. In this case, the overload will depend on the conductivity of the resistors. A capacitor box is installed first. To work with the regulator, you need a welding inverter.
The extender in this situation is selected with or without an amplifier. In the first case, the model will be able to work in continuous mode, however, its capacitors will overheat greatly. If you do not use an amplifier, then this problem will not be. It is more expedient to install the transceiver behind the cover. The isolator is not used in devices of this series. Particular attention when assembling the device is important to give the holders. Clips for them must be selected a small height.
DR 102 Series
Making modifications to this series is quite simple. First of all, experts recommend installing the expander and the condenser box. The coil in this case is used with only one adapter. According to experts, the use of field resistors is permitted. However, it is important to note that using them without zener diodes can be dangerous. The relay overload parameter is at 15-A.
Some experts recommend installing only semiconductor regulators. Next, a triode is used to assemble the device with your own hands. It must be installed behind the contactor. It is important not to damage the expander cover. When starting the modification, the operating voltage is checked, as well as the output resistance. In this case, the contacts should be in the upper position. The operating voltage must be at least 240 V. A valid output resistance parameter is considered normal within 40-50 ohms.
Welding machines of the DR 105 series
This series of spot welding for batteries with their own hands (photo shown below) is going to be problematic. First of all, it is important to note that the wave type transformer is not suitable for modification. Many experts say that it is more expedient to select exactly lowering analogues. The conductivity of the element should be maintained at 4 N.
It is also worth noting that expanders can be installed with different types of comparators. The relay is used with and without a stand. The operating voltage indicator for this type of modification is in the region of 230 V. The holders are more suitable for use with a double-sided handle.
Modifications to the AVR Series
Do-it-yourself spot welding for battery-powered AVRs using a wave transformer. Also, to assemble the device you will need one adapter, which is installed under the expander. Relays are often used low impedance type. First of all, this allows us to solve the problem of overheating modifications.
The input impedance does not increase much during heavy loads. The next step when assembling the device is the transceiver itself. It is advisable to solder the contactors near the capacitor box. Holders are standardly installed last. Thyristors, many experts advise installing a single-junction type. The insulator is used only with mesh winding.
