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 increase the parameter
•
Rotating the knob counterclockwise decrease 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.
