Hi, im Dean from Chicago i been welding a couple months mainly Mig til i received my 225 lx two weeks ago. this thing is sweet, it was shipped with a air cooled torch i called tech and they sent me a water cooled torch it was here in a couple days. Thanks Guys i figured out what all the knobs are about Thanks to the videos that are posted and a freind who has been welding for 45 years. Im not good enough to make chassis repairs yet, It will take time and practice. Thanks Dean.
