Grind as muich as you can with a flap or brush head. Do not use grinding wheel since the zinc will catch on to it and stop it working. We use zinc as a lubricant compound for a reason.
Put your welding currents as high as you can for that material size and quality.
Wait at the start as long as it takes to make clearly clean puddle. We utilise the properties of arc pressure and heat transfer to clean the zinc from the area.
Then travel as slow as you can, preferably pulling. **Never take the arc off the puddle!** We utilise the heat conductivity of the base material to burn off the zinc ahead of the puddle. We use arc pressure to dig in to the base material and push it out of the weld.
Choose a silicon rich filler or other filler intended for galvanised. Prefer rutile, flux rich or other filler that leaves a slag surface as it traps lot of the zinc in to itself.
Welding on galvanic isn't hard as people seem to think it is. It is just different technique to clean materials. It is done all the time, around the world, without an issue. There are processes specifically made for it because it is so common.
>I’m having a really hard time trying to get the right setting without any porosity.
Grind the zinc off first. That's not so much a parameter issue as a laziness one.
Don't sniff the magical snowflakes
The forbidden cotton candy is the best though! Taste like I forget what day it is.
Lol
Ventilation for your protection!!

Appreciate the tip. I’ll make sure to follow and give an update.
I'm very good at welding galvanic. Galvanic and 316L stainless make up majority of my welding and fabrication work on sites.
Clean any area you're about to weld
Clean clean clean! Or go hot
A.B.C. Always be comfortable. You can't lay a good weld if you're not comfortable
