4.06 Power Source Features
Feature Description
Digital Control
• All welding parameters are adjustable
Touch Panel Switches • Touch switches eliminate mechanical damage
Front Control Cover • Protects front panel controls
Digital Meter Volt & Ammeter
• Displays selected weld parameter value
• Displays average weld current when welding
• Displays average 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, while 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)
(shipped activated, field-capable)
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 AS 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.
