ADVANCED DELIVERY SET
About 80% of all industrial compounds using welding are made with arc welding. However, the high current required for welding is not obtained from a conventional AC transformer, but from a more reliable and high-tech device—the so-called welding inverter.
An inverter rectifier first appeared in the market in 1977 and since then it has changed a lot, in accordance with new requirements and technologies. The welding inverter is a device powered by a conventional or an industrial alternating voltage network of 220 or 380 volts. It provides a stable current at the output of the necessary power and voltage to initiate and maintain the welding arc. At the same time, the welding inverter has many settings and is very convenient in operation.
Inverter welding current sources are the same for all types of welding. They differ only in technical characteristics, so a welding inverter can perform any welding. The main types of welding are manual metal arc welding (MMA), tungsten arc inert gas welding (TIG), and semiautomatic metal inert/active gas welding (MIG/MAG).
The main advantages of the inverter:
- Efficiency. Compared with classical transformers and rectifiers, the inverter consumes about 1.5 times less electricity at the same welding current, and at open-circuit operation—8-10 times. In many cases, this allows welding to be done by connecting a welding current source to a household electric grid or to an alternator.
- Compactness. PATON™ welding inverters have small dimensions and weight.
- Steady operation – the voltage drops in the grid practically are almost neutral in their impact the operation of the welding inverter. It uses the most
advanced delivery set protection systems, both from overload and from excessive voltage drops.
- Stable welding arc is a guarantee of reliable operation in all conditions.
- Ease of use. PATON™ welding inverters have modes for a beginner, that is, a person without a welding experience can still use this device with success.
- Low metal splashing —the welding seam turns out neat. The volume of slag and excess metal is minimal. This reduces the work on the further weld processing.
- Any type of electrodes. The wide range of settings of the welding inverter allows you to use virtually any electrodes for welding—depending on the process conditions and the type of metal. It is possible to change the polarity of the current on the electrodes.
