Using a spool gun on Hobart 190 and Lincoln 180 is very easy. All you have to do is unmount the standard welding gun and replace it with a spool gun. There is no necessary requirement for any specialized tools for doing it. This means that you can now get excellent performance for aluminum wire welding without facing any difficulty in changing the guns. Plus, you will be surprised to know that no adapter or control box is needed separately for the spool gun.
