Welders are used for a variety of jobs from building chain link fences to repairing cars and anything metal. Arc welding has been around for a very long time and will continue to be a popular choice for welders due to it's high quality welds and ease of learning and becoming certified. In this article we'll cover the various models available and how they stack up including how they work, including model numbers, descriptions and more.
Arc welding uses direct current (DC) or alternating current (AC). It uses consumable or non consumable electrodes respectively.
It uses the power supply to make an electric arc connecting the electrode and the base material. This process is used to melt the metals to the welding point.
In some cases an inert or semi-inert gas, which is also called a shielding gas and/or evaporating filler material, is used to protect the area being welded. Arc welding has low capital and running costs, which makes it popular.
