Have a Telwin technomig 180...Not the version with euro binzel.... Drawback is short return lead...very short,but easy to fix...I use co2 as protection gas and it works very well...There is a scale up to 2,5mm on co2 gas....If you have thicker material you can set it in deeper penetration.... Use of mixgas,full energi or gasless wire...I Think the benefit is the light weight....Very easy to get the wlding machine out to the Place....Telwin is a big welding Company and deserv its own thread...
...But how long a inverter will last is a Another question...My old Telwin transformer is about 25 years old...Will se how long the new one will last 
...But these invertermig are so easy to weld with...They are light...easy to cary....easy to drag outside...I Think they is the fortune...Because they is so easy to use
