Is there a real difference between say a Lincoln wire, Hobart wire, and a big box wire. They are all Er70s-6 or choose your other filler material and up to certain standards, but what is the difference between mig, flux core, stick electrodes, or tig fillers. Is there enough difference you could have defects or is it a lot of feed ability and flow. I know we had a spool of self shielded flux core for awhile and now switched to Lincoln and all feeding problems went away. We use the big box brand in our mig welder in 30 lb spools due to price but will switch to blue demon next time online for a cheaper price. How are the prices different if it is the same? Are different big box brands different. Menards doesn't even have labels on some of theirs-like no 6013, 7014-just "welding rod"
A student now but really want to weld everyday. Want to learn everything about everything.
