4.05 Power Source Features
Feature Description
New Digital Control
•
Almost all welding parameters are adjustable
Touch Panel Switches
•
Touch switches eliminate mechanical damage
Front Control Cover
•
Protects front panel controls
Digital Meter
•
Displays selected weld parameter value
•
Displays weld current when welding
•
Displays weld current for 20 seconds after weld
has been completed
•
A selected weld parameter value can be adjusted at
any time even while welding
Intelligent Fan Control
•
The intelligent cooling system is designed to
reduce dust and foreign material build-up, whilst
providing optimum cooling.
•
Fan speed reduces approximately 30 seconds after
machine is turned on
•
Fan speed increases when internal components
reaches operating temperature
ON/OFF switch
•
Primary voltage Supply ON/OFF switch located
on rear panel
Voltage Reduction Device (VRD) Reduces the OCV when the power supply is not in
use. Eliminates the need for add on voltage reducers
and has no effect on arc starting.
•
VRD fully complies to IEC 60974-1
•
When Stick mode is selected the green VRD light
is ON when not welding and red when welding.
•
When in TIG modes VRD is off.
Control Knob
•
For the selected weld parameter, rotating the knob
clockwise increases the parameter
•
Rotating the knob counter-clockwise decreases the
parameter
•
A selected weld parameter value can be adjusted at
any time even while welding
•
Pushing the knob in displays actual arc voltage.
Self Diagnosis Using Error Codes
•
An error code is displayed on the Digital Meter
when a problem occurs with Primary supply
voltage or internal component problems. Refer to
troubleshooting guide.
