The choice of a welding inverter is a rather difficult and important matter. If you have already decided to purchase this unit for home use, then you should know about what key points can affect its operation.
Welding Inverter Selection
This unit is designed for
arc welding, it converts the input
alternating current to direct, and through
transistor switches, the constant is converted to alternating current of a higher frequency. After that, it is fed to a high-frequency
welding transformer, where subsequent rectification is performed. Due to the high frequency, it was possible to reduce the size and weight of the
power transformer in comparison with traditional
types of welding equipment. However, the mass and dimensions of the unit are not the most important factors that can influence the acquisition.
If you faced a difficult choice of a welding inverter, then for a start it is worth determining what frequency the device will be used with. If it is needed once or twice a month, or even less, it makes sense to pay attention to a household inverter, and if it comes to much more frequent use, you can purchase a professional unit.
When purchasing a welding machine for the home, you should determine how popular the proposed option is. This is a very important indicator. So, devices of the Multiplaz, SAI 200, and DaVinci brands are in demand.
And the subsequent choice of a welding inverter completely depends on personal wishes. We can say that the final decision depends on:
- specialization of use;
- the desired battery life;
- schemes and the number of devices that are connected to it.
How to choose a welding machine for non-professional use?
The inverter must have good ventilation, as it must be protected from dust, which is so often inside. However, there is no point in overpaying for some special system, it is enough to independently clean the fan after a while, which is very simple to do - you need to remove the case, and then clean the dust with a not very hard brush.
The choice should be influenced by such a significant moment as the presence of built-in protection against power surges. It is worth remembering about the temperature mode of operation of the inverter. It can be noted that some sellers focus on the manufacturer. Typically, the cost of the apparatus of a large manufacturer is higher than not so famous, and the technical characteristics of the units can be identical.
Do not be afraid of the word "household". The welding result is the same when working with such or a professional welding machine, with the exception of certain differences. It all depends on the goals that are set before the unit. Usually for domestic work there is no need to use a professional apparatus.
So, using the above recommendations, you will not have to experience difficulties with such a task as choosing a welding inverter.
