i just bought a HH190 to get a little more power for my hobbyist welding projects. i just have set up the smaller lincoln weld pak 100 mig set up with .025 L56 wire. i figure this will just be dedicated to sheetmetal projects and will share the tank with the HH190 and i want to set the HH190 up for larger stock. i have half a 2lb roll of the .030 L56 wire left so i figure i will try this in the HH190. this will probably be gone soon since i will be playing alot with the HH190. once this is gone i was thinking of putting .035 wire in the unit. what is everyone else doing? and is there a difference between the hobart wire and the L56 wire? i have over15 yrs of using the L56 and have no complaints with it all but i am always ready to try something new. thks bobbobs77vet/37ford4drEastwood digital TIG200HH190Lincoln Invertec 155sLincoln weldpak 100sears/craftsman (lincoln) 50a 240v buzz boxO/A rig Harris gaugesnexion cut 50 dxchicago electric (HF) 240v spot welder
