4.3.5 Arc Force Control
This control is used to adjust the Arc Force on constant current applications. The
control is fully adjustable from 0 to 100%, with 0 being very soft and 100% being
very hard. When adjusting the Arc Force, the low settings will produce a soft arc
and the high settings will produce a more forceful or driving arc. Please note that
the higher settings will produce higher levels of spatter.
The higher setting will create a more stable arc for electrodes that easily become
unstable, such as cellulose (5P).
If you do not know the optimal setting for the electrode you are using, start at the highest
setting and lower it until the arc just begins to become unstable.
4.3.6 Process Control Selector
The Process control selector has three settings, Stick, TIG and Stick . The
Standard 300S has the same characteristics for both Stick settings. The pipe-
welding version has a cellulose characteristic, allowing 1 inch of arc length when
this method of whipping is used.
The TIG position allows Lift Start, which allows contact between material and
electrode without damage to the electrode.
4.3.7 Power-On Indicator
Indicates power on/off. The power indicator will blink if any component is
overheated. Allow the welder to cool down. This may take 3 minutes or more
depending on which component is overheated. The following components are
temperature monitored:
•
Main Transformer
If a 30% duty cycle is exceeded when drawing 400A output current, the Main
Transformer could overheat and shut down the welder. If overheating occurs, wait
1 minute before restarting. This condition can also occur if a 60% duty cycle is
exceeded when at 300Amps output.
•
Main Inductor
If welding at 250 Amps for more than 30 minutes without stopping, the Main
Inductor will overheat and shut down the welder. If this occurs, wait 7-8 minutes
before restarting.
•
Output Capacitor
When welding at the lower current settings in Range 2, or when arc gouging for
long periods, the Output Capacitor may overheat and shut down the welder. If this
occurs, wait 10 minutes before restarting. The temperature sensor will protect the
output capacitor.
•
Input Capacitor :
Should one phase be lost when welding with three-phase input power, current to
the Input Capacitor could increase causing it to potentially overheat or be
destroyed. Wait 10 minutes
before restarting the welder.
•
Fan Motor: Some operation with restricted airflow will overheat the fan motor.
Wait 10 minutes before restarting the welder.
