2 INTRODUCTION
The OrigoArc 458T and OrigoArc 468T are power sources with characteristics constant
current intended for welding with stick electrodes. They can also be used for welding
with the TIG DC (direct current) process.
The OrigoArc 468T has Arc Force, its adjustment change the short circuit current and
the arc penetration.
They allow weld carbon steel, alloy steel, stainless steel, cast iron, aluminun and its
alloys, copper and bronze.
The welding current is set using the potentiometer in the panel or in the optional remote
control.
It´s possible to weld electrodes up to 6,0mm.
The OrigoArc 458T and OrigoArc 468T rectifiers cabinet are strong and easily moved in
the working area. The OrigoArc 468T trolley has a brake and also lifting eyes. The
stationary version can be moved with the aid of a bale truck.
The power trigger circuit of the thyristor maintain the welding current constant comparing
the real current signal with the pre-defined current signal, irrespective of load variation in
the main supply voltage up to ± 10%. This signal comparison does not permit that an
overloading happens limiting the welding current.
They have a thermal overload trip which operates if the temperature becomes too high,
interrupting the welding current, lighting a indicating lamp on the front of the power
source and the fan is on. The thermal overload trip resets automatically when the
temperature has fallen.
