I hate to say it, but welding can be an all encompassing hobby in and of itself, and unless you plan to just push flux wire for mild steel you better plan bigger on your electrical budget.
That being said, I do push flux wire for mild steel. It is in my opinion the absolute easiest type of weld to do. I also have a dual gun, dual bottle, dual regulator MIG setup for steel and aluminum. Literally just drop one gun and pick up the other, I've also got two little suitcase 110V units setup for flux core (and I use them), an AC cracker box that burns rod upto 1/8" almost as fast as I can pick up another rod, a piggy back TIG to run on top of the cracker box for light AC tigging aluminum, and of course an OA rig that hasn't had a welding tip on it in ten years, but its the first way I ever learned how to weld.
One thing in your post got my attention, and I am surprised nobody commented on it. You had a job specifically welding galvanized. I am going to assume you had a proper safety setup, but comment for those who might not know. Welding galvanized is exceptionally hazardous. The fumes are pretty toxic. I do it occasionally, but only outdoors with my flux core rig, and the wind (or a fan) setup to carry the fumes away from me and disburse them.
Anyway, a combo TIG/STICK rig is pretty versatile. For mild steel flux core mig is the easiest way to weld I know of. If you plan to make and repair decorative fences its the way to go and you can plug it in anywhere. Of course the duty cycle will be measured in inches, but its cheap and easy. Even cheaper for me growing up was OA welding. We had a country general store and I had an endless supply of wire clothes hangers for filler rod.
P.S. I am not a welder. I am not good at welding. I would hire a shop in a heartbeat for my more important projects, but I have never had a welding shop do my projects in the time they said or even two or three times the time they said, and by the time they got to my job they forgot what I wanted and did it wrong. That's why I learned to weld aluminum. LOL.
