The main purpose of welding sources is the provision and burning of the welding arc and its ignition. An important parameter of the welding process is its resistance to noise and vibrations. To date, several varieties of power sources for the welding arc are known, among them inverters should be distinguished.
Their advantages are the improvement of the dynamic characteristics of the arc and the size of the power transformer. The use of such technologies contributes to:
- reducing the weight and size of welding machines;
- increase in efficiency;
- improvement of the arc index.
When welding, spatter is minimized, and adjustments to the welding parameters become smooth. As an example of the described equipment, “PN-500 Energy” acts, which will be discussed below.

Weighs "Energy PN-500" 4.5 kg. The device complies with 20 IP degree of protection. The operating temperature range varies from -5 to +40 ° C. The transition time to the battery is 0.05 seconds.
Positive features
Energy PN-500 allows the operator to control operation parameters. The case has a digital display, which is simple. Additional benefits are:
- increased battery life;
- intelligent security system;
- forced cooling system;
- voltage stabilization function.
The sine wave is pretty clean. The design provides for the presence of the RS 232 interface. You can use the battery recharging function.
The unit is universal in use. It has a compact size and low weight. The described voltage inverter is characterized by a nominal frequency of the output voltage, which is - 50 ± 5 Hz. When powered from the mains, the rated output voltage reaches 220V ± 10%. The power overload protection threshold is - 110≤p≤120%. In stabilization mode, the input voltage range is equal to the limit from 110 to 285 V.
Consumer reviews about "PN-500 N"
“Energy PN-500 N”, according to customers, has many advantages. For example, the unit combines a converter and an electronic stabilizer that protects against power surges. The equipment can play the role of an intelligent battery charging module with a training mode for sulfation.
As consumers emphasize, this allows the use of gel and conventional car batteries. After reading the reviews about "Energy PN-500 N", you can understand that quite often this device is compared with household uninterruptible power supplies. The first produces an ideal sinusoidal voltage, provides devices with better power supply, which is also suitable for gas boiler equipment.
The set does not include external batteries, but their use, according to consumers, allows you to choose the operating time of the system in accordance with the wishes. If we build a power system for the boiler based on the described device, this will allow us to create a silent digital and fully autonomous power infrastructure. At the same time, the capacity can be expanded, and the price of the equipment remains quite affordable.
Using the described voltage inverter once and for all, you can get rid of problems with power outages, voltage drops and its surges. Gas equipment, according to users, can be provided with silent power and reliable protection during a power outage. The described modification has a wall mount, and additional space for its placement is not required. The device can be mounted on the wall, near the gas boiler.
User's manual
If you decide to purchase a voltage inverter "Energy PN-500", the instructions for its operation should definitely be studied. From it you can find out that when the input voltage appears, the device will turn on automatically. To force it, you must hold the corresponding button for 4 seconds.
When you hear four short beeps, you can be sure that the self-test mode is complete. If an overload of the output circuit occurs or a malfunction occurs, as well as overheating of the power unit, the load circuit will turn off and the error indication will be triggered. To force the output voltage to be turned off, hold the corresponding button for 4 seconds.
Finally
No matter how high-quality the equipment, it can fail if it is not used correctly. The manufacturer emphasizes that before turning on the device at a low ambient temperature, it is necessary to withstand the device in a warm room for a time that will be enough to warm all parts. This usually takes 2 hours. Operation at ambient temperature outside the permissible parameters may cause the product to refuse to work.
It is necessary to store the equipment in a closed state so that small particles and dust do not get into the product. A periodic check of the device must be carried out once every 12 months. This is for maintenance. As a support during operation, it is necessary to use a solid stationary horizontal surface. A space of 250 mm must be provided on each side of the case for free circulation of air and the exclusion of heat transfer from the device to surrounding objects.
