In one sentence, describe what the following article is about: MIG welding is fast and requires less experience than TIG welding. A MIG torch has a filler wire inside of it, so you can do it with a single hand. MIG joints also cool relatively quickly, but this makes them more brittle. MIG welding is also known as gas metal arc welding (GMAW). Most home improvement stores sell MIG welders. You may also be able to rent one from them. Thread the wire through the MIG machine's reel and out through the tip of the torch. You do not need to force the wire through. Let the wire extend about 14in (0.64cm) beyond the torch. Once you are done setting the wire and have activated the gas, you can begin welding. If you have trouble getting the wire through the torch, chances are it isn't set correctly. Avoid forcing it. Open the torch and adjust the wire's positioning. It doesn't matter which end of the joint you start on. Position the torch so the tip of the flame hits the edges of the metal pieces. Wait for the flame to heat up the pieces, forming a bead of liquid metal in the joint. If the metal splatters, you aren't using enough power. Turn the torch's heat setting up. Avoid using too much power, or else you'll burn through the steel! If the heat melts the metal too quickly, turn the power down until you have a smooth, controllable bead of liquid to work with. Move the torch slowly, holding it at a steady angle at all times. As you push the torch forward, the flame will push the bead along the joint. The heat will also melt the surrounding metal a little. Make sure the joint is filled in smoothly and evenly before you move the torch forward. If you move too quickly, you won't melt the steel enough. The joint will feel flimsy and breakable in your hands. Avoid leaving the flame in place for too long. For thinner pieces of metal, the torch needs to move at a faster pace to avoid melting too much of the metal. MIG welds cool down right away, so it won't be long before the joint is secure. Wait until you no longer feel heat coming up from the metal before handling it. In the meantime, set the torch in a secure location, such as a holster, until it cools as well. Turn off the gas when you're finished welding.
Summary: Use MIG welding to join thicker pieces of metal. Feed the filler wire through the torch and turn on the gas. Hold the torch at a 30-degree angle above the edge of the joint. Move the torch forward to fill in the joint. Let the weld and torch cool before moving them.

In one sentence, describe what the following article is about: Choose between drawing or sketch paper, and buy at least four to seven different pencils in a varying hardness levels. At a minimum, you should get a rubber eraser and a kneaded eraser. You can also purchase colored pencils and charcoal for other drawing projects. Don't forget the pencil sharpener!

A #2 pencil is an "HB" drawing pencil. For softer, darker marks, use pencils B-9B. For harder, lighter marks, use pencils H-9H. A standard set usually comes with pencils 8B, 7B, 6B, 5B, 4B, 3B, 2B, B, HB, F, H, 2H. Online lessons usually break down into either beginner, intermediate, or advanced drawing. Decide on your experience level to help specify what kind of drawing lessons you should look for. Are you just picking up a pencil for the first time? Did you take 1 or 2 classes in school? Or are you an avid artist looking for new skills? Base your search query on your skill level and drawing interests, and browse your results. You can be specific or general with your searches. For beginners, search for something like "Drawing lessons for beginners," "Free basic illustration tutorials," and "Beginner drawing tutorials. For intermediate artists, you can search for something like, "How to draw perspective," "Intermediate drawing lessons," and "Drawing landscapes." For advanced drawers, search for "Drawing mastery course," "Advanced drawing techniques," and "Drawing anatomy." There are countless websites that can get you started. You will get the best instruction if you select websites that seem easy-to-follow and fun. You can follow along with step-by-step instructions with visual aids, watch a video tutorial, download printable PDF instructions, or use a combination approach. Use websites like DeviantArt, Drawspace, Drawing Coach, Academy of Art University, Daily Sketch Challenge, and Pinterest. After you've tried one method, give another approach a shot! You may find you prefer another method after you experiment with a few options. Try a variety of instructions to improve your skills. Maybe at first you followed a step-by-step guide off the internet, but perhaps printing out the instructions and looking at a physical copy will also be helpful. Use search queries on your drawing interests and skill level, and look up tutorials on YouTube. Video instruction can be helpful because you get to watch and see how someone else completes the drawing. You can learn how to draw things like animals, people, flowers, landscapes, and manga. Drawing techniques you can study include highlighting, shading, cross hatching, still life, perspective drawing, and textures. Search for things like "Drawing for beginners," "Drawing faces," "Figure drawing lessons," or "How to draw a rose." There are so many different resources online to learn to draw, though you want to be sure you are following the most reliable, helpful lessons. Review the website before you start. Look for things like the author of the site (accredited website or personal blog), variety of lessons available, experience of the person providing the lesson, the ratings, and number of views.
