also require User's Manual # 990-291.
For the rest of this manual the HF2 High Frequency Inverter Welding Power Supply will simply be called
the
Power Supply
and the HF2 Transformer will simply be called the
Transformer
.
The Power Supply is designed for joining precision small parts at high speed with controllable rise times
using 2 KHz output pulses superimposed on pure DC welding energy. High speed (250 micro-second)
digital feedback automatically controls weld current, voltage, or power, providing more welding
consistency compared to traditional direct energy (AC) or stored energy (CD) technologies.
Microprocessor technology automatically compensates for changes in workpiece resistance, load
inductance, weld transformer saturation, and up to 13% changes in line voltage. The Power Supply uses
IGBT power device technology for precisely controlling the weld energy at both high and low energy
levels.
Easy to use constant weld current, voltage or power feedback ensures repeatable welding and has proven
to extend electrode life in many applications by a factor of five or more. A selectable weld energy limiting
feature also contributes to repeatable welds and high nugget quality. The user can program the Power
Supply using a graphical or numerical interface.
