It's not so bad. A lot of shops will go with one size/type of hard wire, one size/type of flux core, etc. to keep it simple. A place I welded at as a temp was nuts. 100% trace ability, with wire specified by the customer for all processes. If you didn't read the w.p.s. before you started welding and do exactly as instructed, including weighing the spool before and after use plus total weight used-
You were fired immediately. Take off your hood, clean up your tools and leave-fired.

I'm not sure where you're coming from actually. Every profession has technical information to learn and becomes second nature after a while. With all the different types of materials that get welded, there are a lot of terms and specifications that are needed just to name everything in a standardized way.

I will MinnasotaDave. Was hoping the dual shield would allow for 7018 like welds for short run and out of position runs fab'n tractor implements. What I am working on now is a forklift attachment for a front end loader on a Mahindra.

Once you get the regular flux core dialed in I'm sure you'll be happy with the results.
It burns in nice and hot and doesn't really spatter that much. If it spatters a lot, the setting are not quite right.
Here are the Washington Alloy numbers I used on the last job.
Lincoln has a chart you can look at too.
I know the last time I asked HTP/usaweld where their parameters were listed, they didn't have any.

Better than gas shielded mig, about the same as 7018 in my opinion.
But easier than stick for less than ideal body positions while trying to weld vertical and overhead.
You know what less than ideal is - all wedged up under some piece of junk broken hulk that needs to be welded one handed with your off hand but you can only see it with one eye closed

Just remember you can always do multiple passes as long as you clean it and if you need to go vertical, don't you dare go downhill only uphill and you may have better results than mig. If you have slag inclusions than it is failed but it will come with time. And don't stick your head in the smoke plume.

I would respectfully disagree about vertical down - run nice and hot, flux core runs down quite nicely
I do it with thin metal - like 1/8"
I like 6010/11 vertical down on thin stuff too - or to fill a gap before going vertical up.

Wel MinnesotaDave I may be thinking dual shield. My teacher at my tech school, I only took one class so I'm no expert and have little experience with flux core but he said he'd kill any of us who ran flux core downhill. Or he may have been talking about it not being worth it since all they do is thick metal so you want a lot of penetration. I don't know but vertical uphill will give you a little more penetration anyway so I guess learn both.
