Heck I am not a big time welder.  I just mess with it since I am always big on tryin to learn new things.  Welding is an art to me and some of the welds I see on here are amazing.  I had a buddy who built drag racing cars and to say the least his welds were some of the best there is.  He had a friend driving one of his cars when the main shoot broke and the car went off an the road bout 3/4 mile later and flipped end of end think it was like  5 times along with the rolls.  The driver named steve walked away with only a bruised elboy.  They est his speed when he went off the bank at 220 mph.  Ever since watching him build cars ive wanted to learn the skill.  My terms may be off but I am learning just at my pace.
Even with this low end welder I am managing to make some pretty flat even welds with this new Rancor wire. Its a flux core .30 . imo it was night and day diff.
I am gonna be building my bumper this weekend and ill post some of welds so yall can see what I am doing.
