INTRODUCTION
TAF 1251
is a remote-controlled, two-phase AC welding power source designed for
high-throughput, mechanised submerged-arc welding (SAW).
The welding power source converts, via a thyristor bridge-rectifier, the secondary voltage's
sine wave to a square wave with excellent arc ignition and welding characteristics.
The welding power source is fan cooled and is overload protected by a thermal cut-out.
Re-setting takes place automatically as soon as the temperature has reduced to a permitted
level.
