The pressing need to get a good weld seam is forcing more and more organizations to switch to an inverter welding power source. A positive difference from the transformer power elements of the welding arc, inverters stand out for the following outstanding characteristics:
- Significantly smaller dimensions
- Best efficiency
- Lightweight
- Precise and smooth adjustment of the parameters of the welding arc
Inverters are used for these types of welding:
- Plasma arc
- Semiautomatic welding
- Manual welding
- Argon welding
Procedure for preparing the inverter for operation
For guaranteed positive results of welding, it is better to choose an inverter for which an electrode with a diameter of 4 mm is required, but for beginners it is recommended to use 2.5-3 mm. A huge advantage of the inverter is the ability to adjust the current to avoid burning through the metal.
The first step is to establish grounding with a flexible cable to the workpiece to be welded if welding takes place outdoors. Further, depending on the selected electrode, we set the welding mode. After that, it is required to turn on the inverter and hold it over the part to be welded, and specifically at the place of the future seam, and if sparks have gone out at the point of contact between the metal and the electrode, then order and you can start working. Now you need to catch the desired distance from the part to the electrode for a uniform seam, usually about 5 mm. Now you can work normally without fear for safety and welding quality.
