Hey guys. Picked up this "Chicago Electric Mig-100" welder as my first welder. I welded my selector rod with it and my skid plate, but it all of a sudden stopped "arcing" I guess the word is. I know just about nothing when it comes to welding. Basically when I ground what I wanna weld and get the wire on it nothing happens. But it indeed did work. Any thoughts ?

UPDATE: Fixed it, loose ground wire
