Gmaw arc length control
WebJan 10, 2002 · In manual GTAW, the heat of the arc commonly is controlled one of two ways: through the use of a foot pedal or as a static setting on the power source. The foot pedal provides variable control of the welding amperage, or heat. The torch assembly is either water- or air-cooled. A solenoid on the power source activates the flow of shielding … WebAs arc length decreases, the arc cone becomes narrower and the arc is more focused (see Figure 7). The result is a weld bead that is more narrow and ropy and the level of weld penetration may decrease very slightly. Conversely, as arc length increases, the arc cone becomes wider and the arc is broader. The result is a weld bead that is wider ...
