Arc welding is a process for joining metals by applying extreme amounts of heat to melt metal and mix with a molten filler metal, creating a metallurgical bond once it solidifies and cools. Having an arc welder on hand at all times can be handy if you are a hobbyist or you have a workshop at home. The tool lets you weld at higher speeds, with minimal slag and less cleaning afterwards. High-quality arc welders provide better weld pool visibility and eliminate the need to change electrodes and worry about losing stub ends. This way, you can increase productivity and accomplish more jobs quickly and efficiently.
In arc welding, metal should melt under intense heat from the electric arc, which is formed between the electrode (either a wire or a stick) and the actual work. The electrode is either mechanically or manually guided along a joint, and it can be a rod that can carry the current between the work and the tip. Some rods are specially prepared for arc welders. They are designed to conduct current and melt and provide filler metal to a joint. Most welding applications for making steel products typically require the specially prepared wire or rod.
An arc welder does not require you to be an expert in welding. In fact, even with minimal skill, you can get started and operate it with ease. In most applications, the arc welder will not require any flux, and it will keep the process automated. High-end arc welders are versatile and capable of accomplishing different welding processes, like coated electrode arc, inert gas, TIG, submerged, and cored wire arc welding. Equipment and devices for arc welding at home are typically portable and lightweight, making them easy to store and transport. Likewise, they come with all the necessary attachments and accessories you will need for a basic set up in your workshop.
