ARCMASTER 300 ACDC
February 22, 2006 4-7
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
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
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 reach operating temperature
ON/OFF Switch Primary voltage Supply ON/OFF switch located on rear panel
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.
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.
Save/Load Function A total number of 5 programs can be saved into the 300ACDC memory.
SAVE the Current Weld Parameters into Memory.
Press the SAVE button.
Select a memory location by rotating the control knob, 1 to 5 is displayed on
the meter.
After selecting the desired mem-ory location (ie 1 to 5), press the right scroll
button and the machine will give a beep to confirm the weld parameters from
the control panel are saved.
LOAD (retrieve) a Program to Control Panel.
Press the LOAD button.
Select a memory location by rotating the control knob, 1 to 5 is displayed on
the meter.
After selecting the desired memory location (ie 1 to 5), press the right scroll
button and the machine will give a beep to confirm the weld parameters are
loaded onto the control panel.
