Square wave AC power sources for submerged arc welding

The AC power sources TAF 801 and TAF 1251 are using a unique square wave technology suitable for a wide range of AC welding applications. selected from a list and other motors can be programmed manually.

Excellent welding properties
The ESAB Square wave AC power sources convert the secondary voltage from a sinus wave, via a thyristor controlled rectifier bridge, to a square wave arc voltage with excellent arc strike characteristics and with good welding properties. Submerged arc welding with heavy solid wires requires a power source of high capacity. The TAF square wave power sources, make use of the advantages of alternating current:
• No arc blow
• High productivity using Multi-electrode system

Communication
The power sources are designed to be used with the fully digital PEK controller.
Communication is vital in automation applica-tions. Therefore the power source is prepared for communication using most standard protocols like TCP/IP (LAN), CAN or even straight communication with a PLC.
Optional communication modules might be needed depending on type of used protocol.
