I use welpers, the japanese ones, I bought a cheap "hobart" pair at tractor supply for my welder at home, and the cutting edges on them have bad gaps and you have to have the wire on the right portion of it to cut, for the $10 I saved I wish i just got another pair of welpers for home too. Just look them over if you can just like if you were looking at a pair of dykes, close them and hold them up to the light to see how much light makes it through the gap in between the two cutting edges, if theyre tight buy em, if not its really not worth the headache.
