Way to go on your find RA. The Lincoln "Tombstone" is a good little welder to start out with. I have been welding professionally for over 20 years now. Welding took me allover the country until I finally found the right spot to settle. Now, eventhough we are running our own stock, I am still welding. Regardless of what some think, not all ranchers are rich. The oilpatch here in NE Wyoming is keeping me pretty hooked up.
I have 5 different machines all made by Lincoln. They range from the little shop wirefeed machine all the way up to the Pipeliner and even a 600 amp shop machine. My advice to anyone looking to buy a machine is to stick with the name brand stuff put out by companies that actually make welders. There are alot of variables when welding and especially when learning to weld. By choosing a machine from Lincoln, Hobart or Miller, when you have problems while learning, it will most likely be an error on your part and not that of the machine.
6011 is a good rod for what you will be doing. Most pro welders wont use it and call it "farm rod". That means that it is usually so easy to use that even a farmer who dont weld much can achieve success with it. There are several different rod choices that are better, but these rods require more skill to get the desired results.
Sign up for a night class at your local community college or vo-tech. It will be money well spent and you will be glad you did. This route will teach you the proper techniques as well as the theory behind what you are doing. This will make it easier for you to determine the proper plan when faced with a repair or upcoming project. Until you get good, DO NOT weld on anything that could pose a safety hazard to you or others. That is a big can of worms you dont want to deal with.
Remember, you cannot get a good weld on dirty metal. Always work with clean material. Rust and dirt dont weld. They just create voids and weak spots in your weld. If a weld looks like crap on the outside, chances are it looks worse on the inside. Get a piece of 1/2"plate and practice running beads. Pay close attention to the puddle of molten metal immediatly behind your rod tip and watch what it is doing. Watch the edges of the puddle to determine if they are covering the desired area. If the edges of the puddle dont spread out far enough, slow down. If they spread too far, speed up.
Other than messing with cows and horses, welding has been my occupation my whole adult life. I have worked allover in heavy industrial construction as well as shipyards, pipelines, the oilpatch and commercial construction. If you have any questions at all just shoot me a pm and I will give you my number. Congratulations on your new welder.
Good luck Tex
