Machinery and equipment / | Inverter welding ferrous metals |
metal welding – process, which is always considered to be very important in connection ferrous metals by fusing two pieces or sheet materials. Today, welding processes abound, but at the same time, special attention should be paid to a completely new method of - Inverter welding ferrous metals metalschernyh.
What is capable of this type of welding? It's really simple, but at the same time productive. The inverter welding uses a device that is able to create an alternating voltage when connected to a DC power source. By and large, there are some similarities with the conventional arc welding, but the inverter circuit includes a number of new technologies and components that make welding process smooth, precise and higher quality at the lowest cost of electricity and the service life of the device.
Advantages of inverter welding
When using the inverter unit, there are several significant advantages over other methods of welding ferrous metals:
- The average efficiency reaches 90-95%;
- A large range of adjustment modes of the device. It can be adjusted to different current range using thin electrodes, the mass of « spray » It does not increase, and the machine is in a stable manner without overloading;
- Ability to work on one device in several directions, while programming the inverter to a single load;
- Fast ignition of the arc and high arc stability at its long-term retention;
- High-quality weld without pores and cracks after cooling;
- The small size of the unit and ease of transport.
Disadvantages inverter devices
As with any other units, there are also disadvantages, but if properly operate the machine, some can be avoided:
- Electronic equipment is very demanding on the ambient temperature, and humidity;
- Repair inverter device is more expensive than usual. But, and the life of these devices obviously higher than that of traditional welding transformers;
- Inverter afraid of dust, but everything is solved if, after each of its operation to purge the internal components of the unit with compressed air;
- The cost of the inverter device in 2 times higher than that of conventional welding transformer.
All of these disadvantages to the above advantages still quite small and if the inverter unit to be used in professional directions and daily work with ferrous metals, the benefits are more than cover all the shortcomings.
Operating modes of the inverter welding
During operation of the welding inverter, many have difficulty in terms of the use of certain modes of operation, or there is a complete shutdown of the unit. When using this product, it is very important to maintain the temperature regime. If the environment is warmed to a temperature above zero, the unit will work without problems, but there are limits (40) in which he simply turned off, triggered overheating protection.
The work in sub-zero temperatures, complicated and sometimes even impossible. Electronics Inverter dislikes « Frost » and so after a few minutes of operation can work or an overload protection device in a cold room just will not start.
Types of welding inverter
When choosing a modern welding inverters important not to rush into buying. In this regard, it is important to weigh all the pros and cons of the device to pick up his power, operational modes and capabilities.
Very often you can hear in the proposals for the inverters, the term « home », but there is nothing dangerous if you need a machine for home use, as work with svarochnikom can be continuously used for about 20 minutes with a break for cooling of up to 1 hour . Professional inverter is capable of much greater opportunities. Typically, these inverter units can be used around the clock with short breaks between 8 hour shift schedule. I would like to note that the quality of the seam in both cases remains the same, the only difference is only in its length and speed.
Price category welding inverters
Quite often, the choice of welding inverter, the buyer price range is reduced to the lowest price, but it is not the right move. Before purchasing you need to analyze the price with which they are associated in varying modifications and, where it is possible to sacrifice functionality for the best price.
Frankly, cheap inverters is not worth taking, and it should be done only after careful verification of each operation. Also, do not take and professional devices for home use, since their high price is not justified in normal operation. Ideal acquire welding inverters with an average cost and functionality. Given that the budget option may cost the price of 6-7 thousand rubles. And the professional inverter from 20 thousand. Rubles, the average data segment units is chosen in the range of 10-15 thousand. Rubles.
Choose manufacturer of welding inverter
Rarely is the high price of svarochnik be a powerful argument in favor of quality. As a rule, the larger scale production and the manufacturer's brand value, the better, and the price of these manufacturers offer more affordable. But, unfortunately, there are exceptions to the rule.
When selecting the inverter for welding manufacturer should pay attention to the presence of your nearest service center instructions in plain language to the buyer, the clarity of the instructions of use features, quality certificate.
