Welding In The Dark

Here's a quick video of welding the hinges for my shed. I had to elongate the hinges to make them work in the opening, and on the door as the door itself is recessed behind the trim. If you don't have it or can't buy it, make it! In the video, I am MIG welding mild steel plates to premade steel hinges. MIG, which stands for metal inert gas, is an arc welding process in which steel wire is feed through a hand held, trigger operated gun. Electricity flows throw the wire and when it contacts the metal you're welding, it melts because the current is greater than the welding wire can withstand. Voltage is roughly 20-25 volts DC and the amperage can range from 5 all the way up to 1,000 plus amps! The 3/16ths inches mild steel I am welding required about 65-70 amps. When the wire contacts the metal to be welded, called the base metal, the welding wire melts and the current is returned through the ground clamp which is attached to the metal work piece. The molten metal, which is called the puddle, is protected from atmospheric contaminants by an inert gas called shielding gas. Commonly argon or carbon dioxide or a mixture of the two. Thanks for watching and have a great day!
