Has anyone ran this stuff before? I have typically ran l-56 in my mig machines. But I bought a mm251 and it came with about 20# left on the a 30# spool. It is 035 70s6 wire. I have been pretty happy with it. I looked up the prices on it and a 30# spool costs $40 or so with no shipping cost. It is the same costs to buy that online as 10# l56 is from a big box store in my town. Definitely impressed.
