STEALTH DIGI-ARC 160PFC MV
2 SUMMARY
2.1 Brief Introduction
The DIGI-ARC 160PFC MV welding machine features the latest Pulse Width
Modulation (PWM) technology and Insulated Gate Bipolar Transistor (IGBT) power
module, which can change work frequency to medium frequency so as to replace the
traditional large transformer with a medium frequency transformer – making it smaller,
portable lightweight and low consumption.
The DIGI-ARC 160PFC MV offers excellent performance with: constant current output
for a stable welding arc; fast dynamic response speed to reduce impact from the arc
length fluctuation to the current; accurate stepless current adjustment and pre-setting
function.
There are further automatic protection functions for under voltage, over-current,
over-heat, etc. In the event of any failure, the alarm on the front panel lights and the
output current is simultaneously cut off. This function provides for safe operation and
can extend the working life of the machine.
In MMA operation, if the electrode touches a workpiece for over two seconds the
welding current will automatically drop to the minimum current to protect the electrode.
While in TIG operation, the minimum current will be output initially until the arc is
ignited by lifting method. The output current rises to the preset value to protect the
electrode. At the same time, the arc force and hot start will be provided with MMA
operation.
