I'm a practicing engineer and have been taking welding classes for the past year and half continuously.
I am taking classes at a local community college as well, but it seems like the majority of your issues are into the program offerings of your particular college, and your expectations of how you wanted to be taught.
The choices we had for any entry-level welder with no experience were as follows:
Survey Class/Welding Hobbyists and Artists: 18 weeks, stick, flux core/dual shielded, tig, mig; flux core and mig were not emphasized--probably 2 weeks total for both; you come in with a project and the instructors help you with it
Beginning Stick / Flux Core: 18 weeks, flux core was given about a week, you had to produce 3/8" thick test coupons for BOTH stick and flux core, for a face and root bend test
Beginning Tig / Mig: 18 weeks, mig was given about a week, you had to produce 3/8" thick test coupons for BOTH tig and flux core for a face and root bend test.
Out of the 3 paths to take, there is very little emphasis on semi-automatic (wire feed) processes, because once you can prove that you can weld using stick or tig, getting your settings for the wire feed machine and producing solid, even visually appealing welds should only take you 30 minutes, tops.
I'm in the advanced tig class this semester, and I haven't touched the wire feed machine all semester. Last Thursday, I set the wire feed machine up in 10 minutes, and welded my test coupons in about half an hour, including proper inter-*** temp checks. That shows how little there is to wire feed welding.
If you can stick weld well, you will far and away have a better understanding of travel speed, angle, puddle control, and heat control than someone that has only wire feed experience. The guys who come into this program with "years" of welding experience (mostly home hobbyists with wire feed machines and big egos) are often humbled by students with no welding experience but a willingness to learn the hard processes first.
Gas welding is very much like tig welding, so they are analogous in the motor control and skills needed.
