I have this older version, like the one I added. The one from your link is probably newer, I see that it has some displays, etc. With this model I did not deal so I will not talk about durability but I am of the opinion that it is rather unnecessary, in addition, this migoma has a gradual regulation of current and there is no regulation voltage so that the display shows something is not very useful since you can not change it anyway. If there was a smooth regulation of the current it's different. Take also into account that they are not like looking at some of the cheaper migomatów, which means the most important elements such as transformer, feeder can be made reliably, and on "bajery" they could save so they can be emergency. Rather, I would take this older one, although in a newer version it is 4x4. It is better to weld on a longer or bent cord.
