    Why is there no amperage control on a MIG welding power

    MIG welding power sources have what is known as a 'constant voltage' output characteristic (Fig. 1). The arc voltage is established by setting the output voltage on the power supply. The power source will then supply sufficient welding current to melt the welding electrode at the rate required to maintain the preset voltage (or relative arc Constant Current vs. Constant Voltage OutputConversely, the Gas Metal Arc Welding (GMAW) process (aka MIG) and the Flux Cored Arc Welding (FCAW) process (aka flux core) are both generally considered semi-automatic processes. This means that you still hold the welding gun in your hand and control travel angle, work angle, travel speed and contact tip to work distance (CTWD)) by hand.
