What welding inverters are better
Each inverter has a number of characteristics that you need to pay attention to before buying it. Consider the main ones:
PV
PV - the ratio of the operating cycle to the cooling period, is indicated as a percentage and is calculated for a 10-minute period. For example, a 50% PV indicates the need for a five-minute rest after 5 minutes of continuous work.
Accordingly, the higher this indicator is, the longer the device will be able to operate and less time will be spent on forced breaks.
Welding current
It all depends on the thickness of the workpiece and the diameter of the electrode, so the current can always be adjusted. The main thing - that the stock was sufficient.
For most works with universal electrodes 4 mm, 120-200 A will suffice. But if you have to work with thick rods and powerful blanks, the inverter must provide at least 250-350 A.
No-load voltage
Voltage idling determines the ease of ignition and affects the stability of the arc. Novice users should refer to models with indicators of 60-90 V. Experienced welders will suit devices with a wider range from 40 to 90 V.
We will touch only the most useful ones:
1. Arc Force or "Fast and the Furious" - increases the stability of the welding arc.
2. Anti Stick - automatically changes the current flow when the electrode sticks.
3. Hot Start - simplifies the process of arc formation when working with low-quality electrodes or welding oxidized metal.
4. VRD (Voltage Reduction DeВice) - lowers the no-load voltage to 9-12 V, safe for humans. With the start of the welding process, the operating parameters are automatically restored.
The rest of the nuances of choosing a welder beginners can learn from our article: how to choose a welding inverter.
The best inverters for manual MMA welding
This section presents inverter devices for the simplest type of welding - coated electrodes.
