ok heres my .02 that welder will do everything you need to do and more. I have the 120 amp model and it works well (I used to weld for a living) you can make flux core look ok with a lot of practice but it rots out quicker. weld with gas its cleaner looks better and will not smoke you out as quick. (I use flux core for junk welding) make sure you have the propper wire and gas for what you are welding(Harbor Freight does not know what you need) find a welding supply shop locally and let them know what you are doing they will be able to get you the right stuff. dont bother with the 20 cubic foot bottle they sell you will only get about 45 or so minutes of welding out of the bottle once again welding supply place. I have 60 Cubic foot bottles its the minimum I would use. and finally buy a welding instruction book and lots of scrap and practice lots with machine settings etc(being able to properly set the machine up is almost half the battle). once again just my .02
