6. OIL PRESSURE GAUGE
The gauge displays the engine oil pressure when the engine is running.
7. ENGINE PROTECTION
The yellow engine protection light remains off with proper oil pressure and under normal operating temperatures. If the light turns on, the engine protection system will stop the engine. Check for proper oil level and add oil if necessary. Check for loose or disconnected leads at the oil pressure sender located on the engine. The light will remain on when the engine has been shut down due to low oil pressure or over-temperature condition.
8. BATTERY CHARGING LIGHT
The yellow engine alternator light is off when battery charging system is functioning normally. If light turns on, the engine protection system will shut down the engine. Check the Engine cooling blower belt. Also the alternator or the voltage regulator may not be operating correctly. The light may also come on due to a faulty flashing circuit. The light will remain on when the engine is stopped and the run/stop switch is in the run position.
WELDING CONTROLS (Items 9 through 17)
9.OUTPUT CONTROL: The OUTPUT dial is used to preset the output voltage or current as displayed on the digital meters for the four welding modes. When in the CC-STICK, DOWNHILL PIPE or CV-WIRE modes and when a remote control is connected to the 6-Pin or 14-Pin Connector, the auto-sensing circuit automatically switches the OUTPUT CONTROL from control at the welder to the remote control. In the CV-WIRE mode, when the wire feeder control cable is connected to the 14-pin connector the auto- sensing circuit automatically makes OUTPUT CONTROL inactive and the wire feeder voltage control active.
When in the TOUCH START TIG mode and when a Amptrol is connected to the 6-pin Connector, the OUTPUT dial is used to set the maximum current range of the CURRENT CONTROL of the Amptrol.
10. DIGITAL OUTPUT METERS:
The digital meters allow the output voltage (CV-WIRE mode) or current (CC-STICK, DOWNHILL PIPE and TIG modes) to be set prior to welding using the OUTPUT control knob. During welding, the meters display the actual output voltage (VOLTS) and current (AMPS). A memory feature holds the display of both meters on the seven seconds after welding is stopped. This allows the operator to read the actual current and voltage just prior to when welding was ceased. While the display is being held the left-most decimal point in each display will be flashing. The accuracy of the meters is ± 3%.
11. WELD MODE SELECTOR SWITCH:
(Provides four selectable welding modes)
CV-WIRE
DOWNHILL PIPE
CC-STICK
TOUCH START TIG
12. ARC CONTROL:
The ARC CONTROL WIRE/STICK knob is active in the WIRE and STICK modes, and has different functions in these modes. This control is not active in the TIG mode.
CC-STICK mode: In this mode, the ARC CONTROL knob sets the short circuit current (arc-force) during stick welding. Increasing the number from -10(Soft) to +10 (Crisp) increases the short circuit current and prevents sticking of the electrode to the plate while welding. This can also increase spatter. It is recommended that the ARC CONTROL be set to the minimum number without electrode sticking. Start with a setting at 0.
DOWNHILL PIPE mode: In this mode, the ARC CONTROL knob sets the short circuit current (arc-force) during stick welding to adjust for a soft or a more forceful digging arc (Crisp). Increasing the number from -10 (Soft) to +10 (Crisp) increases the short circuit current which results in a more forceful digging arc. Typically a forceful digging arc is preferred for root and hot passes. A softer arc is preferred for fill and cap passes where weld puddle control and deposition (“stacking” of iron) are key to fast travel speeds. It is recommended that the ARC CONTROL be set initially at 0.
CV-WIRE mode: In this mode, turning the ARC CONTROL knob from -10(soft) to +10(crisp) changes the arc from soft and washed-in to crisp and narrow. It acts as an inductance/pinch control. The proper setting depends on the procedure and operator preference. Start with a setting of 0.
13. WELDING TERMINALS SWITCH
In the WELD TERMINALS ON position, the output is electrically hot all the time. In the REMOTELY CONTROLLED position, the output is controlled by a wire feeder or amptrol device, and is electrically off until a remote switch is depressed.
