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...
