thanks Paul.  they sure are a hand rod to have for a lot of reasons

Thanks Martin,   I think I had pretty good instructors in welding school but they didn't go into details either.  

thanks Martin, I am not really sure how much more it occurs on plain grades without the low carbon. Might do a live call and go into carbide precipitation a bit deeper. 

That pipe superintendent was kind of an ass and fortunately stayed in his office most of the time.

I don't remember what the procedure called for since it was over 30 years ago but buffing with a 3m fiber wheel before welding was standard practice.

strength should be similar.  

welcome

they look pretty good to me.  on the ends, you might want to start letting off the pedal about 3 or 4 dabs from the end.  if you need practice you can just start an inch from the end and practice tapering amps and adding a tad more filler metal on the very end while you taper amps....good job tho

good point Martin.  I think the spray transfer lessens the need to stay on leading edge.  I will be doing cut and etch video pretty soon so I will pay close attention that..I am not sure inductance is set by trim....I  think trim is more arc length

those settings seem close enough to work although you might bump up to 24v.  could be too long a stickout or gun angle.
