hi this is my first post so hello to all you other welders. i have had a german mig set for a few years now and want to get it serviced.the thing is i don't know of anybody who deals with my type of welder,i don't know who manufactures it. it's a twin mig 170a turbo. at my old job the maintenance guy who dealt with the 3 phase sets had a contact at a rental firm.well one welder was deemed 'unfit for use' one day and was removed from hire (that was his reason anyway) and i ended up with a top quality welder less than 3 months old. Mint! it has 6 power settings on it, auto compensates the wire feed speed when you switch the amps switch and can take a 15k reel.sorry about the lack of detail,i'll have to get a photo on here for you to view. it's a crack on machine and it's never had any issues,i wanna get it serviced so it stays this way.anybody know anything about my set????? thanks for reading. gregg
