Spot welding for accumulators by one's own hands: instruction

In different areas, spot welding for accumulators with their own hands is used. The characteristics of devices on the market are different. Modern devices are expensive, and it is problematic to acquire them. In order to determine the assembly, you must first familiarize yourself with the existing types of devices.

Separate contact, as well as condenser 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.

Condenser welding

Condenser spot welding for batteries with their own hands is made 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 need to use a welding inverter. Many experts recommend not using high-capacity capacitors.

The thyristor unit is attached to the holder. Closing resistors are used to close the system. Next, to assemble the device (contact spot welding for batteries) with your own hands, you will need a tester. When turning on the device, it is important to measure the resistance before the input contacts. This parameter must lie within 30-40 ohms.

Features of resistance welding

Contact spot welding for batteries with their own hands is quite easy. Many experts recommend the use of high-voltage boxes. Resistors can only be installed after the adapter. In this case, the expander box must withstand a voltage of 300 V. If you believe the experts, the modulator will not be required during assembly. Solve the problem with increased voltage can be with a simple diode resistor. The relay for many modifications is of a switched type.

The conductivity parameter at the output is on average 5 microns. Next, to make the device 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 oven

Spot welding for batteries with their own hands from the microwave is done quite simply. The first thing to do is to remove the radiator from the model. Transformer for assembly is better to apply at 20 watts. Some experts recommend the capacitor block to use a small capacity. 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 conductivity parameter at the output must be at least 4 microns. Next, to assemble the modification with your own hands, the amplifier with a triode is taken.

To install these elements, you will need a conventional welding inverter. However, before the triode soldering, the output impedance at the cathode is checked. This parameter should not exceed 40 ohms. Contactors in the assembly are often used semiconductor type. In the installation they are very simple. Some solder them immediately after the zener diodes.

Instructions for assembling the model on 3-A

On 3-A spot welding for batteries with their own hands is collected quite simply. First of all, a wave transformer is selected. The relay is only used with a rubber lining. Quite often the transceivers are of the single-pole type. The overload indicator should be at least 300 N. They are rarely used for assembling in this situation. It is also worth noting that when folding the device with your own hands, you must use a capacitor of 4 pF.

Contactors in this case are used with field effect transistors. Find them in the store is quite problematic. However, these elements can always be replaced by linear analogs. The resistance parameter at the input does not exceed 44 ohms. Regulating boxes for hot start are used diode type. Comparators for the collection of modifications to 3-A are not required. At the end of the job, it remains only to fix the holder of the device.

10-A device

At 10-A spot welding for batteries with their own hands is added only on the basis of a wave transformer. If experts in this field are to be believed, then the adapter must be soldered first. High-capacity capacitors should not be used. Also worth noting that many modifications have two triodes. After installing the transceiver, a capacitor box is soldered.

Further, when assembling the device with your own hands, a comparator is installed. Modifications of the unrestricted species are very rare. Holders are used with and without handles. Triodes are often mounted without zener diodes. It is also worth noting that nowadays modifications with rotary controls are more popular.

Self-made apparatus for 15-A

At 15-A spot welding for batteries with their own hands is quite easy. For this purpose, the expander is of a dipole type. However, first of all, the contact adapter is used in the assembly. Condenser box is installed behind the expander. It is also worth noting that models of low-resistance type are not recommended. After installing the adapter, a transformer is placed.

Next, to make the device on the 15-A 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 installed on the overlays. A thyristor for the assembly of modifications is more appropriate to use a regulatory type.

Zener diodes are rarely installed on machines. Some experts recommend using only FETs. However, they have a very low conductivity index and there are problems with the stabilization of the output current.

Devices with KU 202 triggers

With flip-flops KU 202, spot welding for batteries with their own hands is done using wave transformers. Before assembling the model, it is important to prepare the reel as well as the expander. Many experts do not recommend the use of cheap capacitors of small capacity. Holders should be installed on the device in the last place.

It is also worth noting that after installing the adapter, a stabilizer is taken. Solder it near the regulator. For this purpose, you need to use a welding inverter. Diode transistors in this case are established quite rarely. Modifications with triodes are also not very popular. Holders are often used with insulators.

Modifications of the DR 101 series

Make a modification of this series can be based on a transceiver or wave transformer. The power of the device should average 300 watts. In this case, the overload will depend on the conductivity of the resistors. The condenser box is installed first. To work with the regulator you will need a welding inverter.

The expander in this situation is selected with or without an amplifier. In the first case, the model will be able to work in a continuous mode, however, it will have a severe overheating of the capacitors. If you do not use an amplifier, then this problem will not be. It is more expedient to install a transceiver behind an overlay. The insulator is not used in this series. It is important to give special attention to the holders when assembling the device. Clamps for them must be selected at a small height.

Devices of the series DR 102

Make modifications to this series is quite simple. First of all, experts recommend to install the expander and the capacitor box. The coil in this case is used with only one adapter. According to experts, field resistors are allowed to be used. However, it is important to note that it can be dangerous to use them without zener diodes. The relay overload parameter is at the level of 15-A.

Some experts recommend installing only semiconductor regulators. Next, to assemble the device with their own hands, a triode is used. You need to install it behind the contactor. It is important not to damage the expander plate. When the modification is run, the operating voltage is checked, as well as the output resistance. The contacts must be in the up position. The operating voltage must be at least 240 V. The permissible resistance parameter at the output is considered normal within 40-50 Ohm.

Welding machines series DR 105

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 a wave-type transformer is not suitable for modification. Many experts say that it is more expedient to select the lowering analogs. The conductivity of the element should be maintained at 4 N.

It is also worth noting that expanders can be installed with comparators of different types. The relay is used with the rack and without it. The working voltage indicator for the modification of this type is in the vicinity of 230 V. The holders are more suitable for use with a two-sided handle.

Modifications of the AVR series

There is a spot welding for the batteries by the hands of the AVR using a wave transformer. Also for the assembly of the device you need one adapter, which is installed under the expander. The relay is often used of low-resistance type. First of all, it allows to solve the problem with overheating of the modification.

The input resistance in this case is not greatly increased during heavy loads. The next step in the assembly of the device is put directly transceiver. It is better to solder the contactors near the capacitor box. Holders are installed as standard last. Thyristors many experts advise to install the unijunction type. The isolator is only used with a grid winding.
