Inverter-type welding semiautomatic devices: an overview of the best models
Semiautomatic machines are very productive due to the continuous wire feed and the absence of slag after welding, which reduces the subsequent processing of the seam. But how to choose the optimal model so that it sufficiently melts thick metal and does not burn thin? This article presents the best inverter-type welding semiautomatic devices, all of which were selected based on user feedback and key equipment characteristics.
The selection of goods was carried out on the basis of reviews, opinions and ratings of users posted on various resources on the Internet. All information is taken from public sources.

Semi-automatic welding inverter with a wire thickness of 0.6-0.8 mm and a metal thickness of 0.5-2.5 mm
Semiautomatic devices, which are designed for a small thickness of metal, belong to the category of household. The current strength is regulated from 20 to 200 A, but the actual data may not correspond to the passport, so you should not count on the maximum performance. Such devices differ in small dimensions 200x300x500 mm, which is convenient for transportation. The low weight of 10-13 kg allows them to be used at a height, provided that a long gas hose comes from the cylinder.
When choosing a semiautomatic device for thin metal, it is important to pay attention to the possibility of lowering the current strength, which will allow you to cook sheet steel and even tin without burning. It is better that this indicator starts from 10 A. Semiautomatic devices with a wire of 0.6-0.8 mm work with standard and reduced coils, therefore, in addition to the household sphere, they have found application in service stations and body repairs.
Thanks to inverter technology, current consumption from the network is reduced and less load is created, which allows them to be used freely in the garage and home workshop. Some units have the ability to cook MMA, not just MIG / MAG.
