Operation of CWG
Ensure you are familiar with the functionality, operation
and all warnings associated with this equipment before
attempting any form of operation.
5.1
Basic CWG Operation and Monitoring
To start the CWG:
1. Check all personnel are clear of the CWG unit.
2. Press the Engine Start button (1).
3. The unit will move through a pre-start
sequence, then crank the engine.
To stop the CWG:
1. Push the Compressor Stop switch, if running
(see over page)
2. Press the Engine Stop button (2).
3. The unit will run a cool down sequence, then
cut the engine.
4. To cancel the cooldown sequence, press and
hold the Engine Stop button, then press the
return button (3).
5. In case of emergency, press the CWG
Emergency Stop button (see over page). This
should only be done in an emergency situation
as it bypasses the engine’s cooldown
sequence.
Monitoring the CWG:
Pressing the Engine Monitoring button (4)
displays the engine oil pressure, RPM and
operating hours.
Pressing the Alternator Monitoring button (5)
displays the alternator voltage, frequency and
current draw.
5.2
Utilising the 240V AC
The 240V AC power can be utilised at any time that
the CWG is running. However, to prevent stalling the
engine, the air compressor will be shut down at high
current draw (approximately 6A). At extremely high
current draw (20A), the clutch will also be disengaged.
5.2.1
Operating the Kemppi Welder
Due to the high yet intermittant current draw of arc
welding, it is recommended that the the air compressor
be switched off and clutch disengaged before welding
commences. Operating the air compressor while
welding may adversely affect the longevity of the
clutch.
