So I'm preparing to weld a set of trusses to a D60 front and 14b rear. I got some high-nickel MIG wire for the center sections (nodular iron/cast steel whatever it really is) and my question is can the high-nickel wire be used on the tubes as well...or is nickel wire not as awesome for the mild steel work? I want to stagger the welds far apart, but in order to switch back to regular MIG wire I'll be switching all the time, and I'll be wasting a ton of wire in the process. That said...presuming pre-heating and controlled cooling etc. is there any reason regular MIG wire can't/shouldn't be used for the whole project - centers and tubes?
