Getting Started
Before Starting Your EnPak
Make sure the emergency brake is on and there is power to the EnPak remote panel. This could be a
master switch or EnPak switch. Make sure to check all uids and belts before starting.
First Start of the Day
Turn the Engine Control Switch to the Start position and release. The EnPak warning will beep and
automatic starting sequence begins. Allow the EnPak engine to warm up before work begins.
Engine Stop
Turn Engine Control Switch to OFF position.
Auto Start/Stop Function
To enable the auto start/stop feature place the Engine Control Switch in the Auto Start/Stop position.
To disable the auto/start top feature, place the Engine Control Switch in the Auto-Speed position.
Turn the Compressor On or Off
To turn the compressor on or off, position the compressor switch in the I (on) or O (off) position.
Battery Charge Mode
To enable the battery charge/crank assist feature, place the Charge/Weld switch in the charge
position and place the process switch in the position matching voltage of the battery being charged.
Chassis Power Mode
To enable the Chassis Power feature, place the Charge/Weld switch in the charge position and place
the process switch in the Chassis Power 12 V position. When using the EnPak to keep the truck
battery charged for multiple lights or other items, use the Chassis Power mode for high amperage
applications.

Process Switch
The process switch works in conjunction with Charge/Weld Switch. Use switch to select weld process
and battery charge process – see table below.
Setting a GFCI from the EnPak Generator
The GFCI must see 120 V before setting. Start the EnPak, access the service menu as described
above, select “RPM SET”. Press and release the control to access the speed menu, select “3600”,
then press and release again to save selection. This will increase engine speed to 3600 rpm’s.
Now set the GFCI. Access the service menu and select “RPM SET” again, press and release the
control to access the speed menu and select “AUTO”, then press and release again to save selection.
The engine should go back to idle speed.
Process Switch Setting Typical Process Applications (DC Only)
OUTPUT ON
Output On – GMAW/FCAW (MIG)
MIG solid wire and dual shield ux core use a voltage sensing (VS)
feeder that does not require a control cable back to the welder/gen-
erator.
Output On – FCAW-S (Electrode Negative)
No Gas
FCAW (Flux Cored Arc Welding – self shielded) uses a voltage sensing
(VS) feeder that does not require a control cable back to the welder/
generator.
Output On – SMAW (STICK XX18 and
STICK XX10) Stick welding. Strike an arc to start welding
Output On – GTAW (Lift-Arc TIG) Lift-Arc TIG: touch tungsten to work and lift to start welding. Uses
circuitry internal to the welder/generator to aid arc start.
Output On – Aluminum Aluminum solid wire uses a remote connected spoolgun accessory.
BATTERY
CHARGE
Battery Charge 12 V Battery charging or jump starting with a 12 volt system.
Battery Charge 24 V Battery charging or jump starting with a 24 volt system.
Chassis Power 12 V Powering large 12 volt loads on vehicle such as electric cranes, lights,
or vehicle systems.

Service Menu
To access the service menu, press and hold the Adjust Control/Select Button for 5 seconds, then
release. Rotate the knob to scroll through the menu items. Press and release the control to access
the options and information within each menu item.

Codes Shown on EnPak Remote Control Panel Display
You could see a code show up on the EnPak screen to let you know there is some type of issue.
Check the manual for error code reference to help repair the issue. Resetting of Charge/Weld codes
can be done by either: changing position of the charge/weld switch; change positions of the process
select switch; cycle unit power off/on. Resetting of Air Compressor codes can be done by switching
the compressor Off, then On.
