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.
4.3.7 Process Control Selector
SMAW - Use for SMAW (Stick)
GMAW (Short) – Use for GMAW-S (MIG) short-arc welding.
GMAW (Spray) – Use for either GMAW spray transfer or FCAW
.
4.3.8 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 at 300 Amps 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.
4.3.9 Remote Control Connector
Units come standard with a 14-pin panel mounted female socket metal shell
connector. The remote control function is automatically activated when a pin
compatible remote control is plugged into the connector.
4.3.10 Input Power Cord
The standard factory installed input power cable measures 12 ft. if additional length
of power cable was not ordered as an option.
