Drawn-Arc: Welding with Alternating Current (AC)

When welding vehicle parts (e.g., brackets, bodies), AC inverters have been special used in automotive industry effective for years. Thanks to this AC-technology, the preparation of the component surface requires less effort, since the heat of the alternating current has a cleaning effect. Reversing the polarity is possible in this case as well. This, in conjunction with programming tailored to the respective stud and motor-controlled welding guns or welding heads, makes it possible to meet special requirements for high-quality welded joints for the market-specific special studs used in the automobile industry. Since welding with alternating current and engine-driven welding guns or welding heads, respectively, is more complex in terms of the equipment, this technology is more expensive compared to direct current.
