When you compare the price of stick rods to MIG wire, your not getting a even comparison of them weight wise. When you stick weld, your only getting about a 50% deposition weight. In plainer terms,for every 10lb of rod you burn your only actually putting down 5lb of weld material while the remainder is used up in the weight of the coating. With MIG welding, you get around 95-98% deposition rate, depending on wire type (ie flux core-vs solid-vs whatever). That's one of the reasons MIG is so much faster, you can put down almost twice as much material in any given time. There is a misconception that MIG is only a production process, it doesn't get good penetration, etc etc. These are all myths. The main difference between MIG and stick is the speed. Pretty much any rod you can get for stick work, you can get a comparable wire for MIG, be it gas shielded or flux cored. With the flux cored variety, you have basically the same field capabilities as you do with a stick, and I can tell you from experience that you can also use gas shielded, in the field, as long as you have something to block the drafts on a windy day. As for penetration, the same thing applies for any welding process, if you get your settings right, one will penetrate and hold just as good as the next using a comparable and proper type of filler material. If your just starting out, there are alot of good welding books available that will explain all the processes, the rod/wire types, the coating types, etc, etc, etc. Personally I believe the best training is OJT, but you have to know a little about what your doing before you start, and a good book is the best way to go. Just another .02.....Wayne
