Arc welding is nothing more than a process of joining two pieces of metal into a single solid piece. To achieve this, the heat of an electric arc is concentrated on the edges of two pieces of metal that are to be joined. The metal melts, while the edges are still molten, additional melted metal is added.

Arc welders generally  come with a load of helpful features. Equipments with unlimited amperage control enable you to create professional welds. The lightweight and yet sturdily built models make this type of welder convenient to carry around and durable enough to withstand tough use. There are some models of arc welders that have thermostatic heat protection features and a roll bar design to give the unit full protection against damage.
