Arc welding apparatus are designed to weld metal together with a consumable welding rod. When the electrode is held in the holder it is placed near the base of grounded metal, high-amperage electric arc across the gap between the surfaces. The resulting arc generates sufficient to melt as consumable electrode metal and heat. The two molten metals then puddle together, and when cooled, form a permanent homogeneous joint between the two surfaces. In addition, by using special cutting rods and the right technique, you can also use an arc welder to cut through the ferrous metal.
Prepare the welding machine by inserting both the base and the welding rod handle lead into their respective color-coded on the side of the machine. Adjust the welding current to the highest position.
Mark a clear line on a steel or cast iron with a piece of engineer's chalk.
Holding the bare end of the rod in a special groove cut into a front side of the welding arm so that the pin protrudes in front of the right arm. Don a pair of welding gloves and welding protective mask slip over your head, not down the visor.
