General Information

Optional Equipment Compatibility
While VMAC strives to design systems compatible with optional OEM equipment (such as running boards), it is impractical to develop systems that accommodate every OEM and aftermarket option or add-on. Whenever possible, VMAC endeavors to advise of compatibility issues in the “Additional Application Information” section of the manual. Even when specific optional equipment is determined by VMAC to be incompatible, it does not preclude the vehicle upfitter or end user from modifying the optional equipment to make it compatible with the installed VMAC system. VMAC does not warrant or accept responsibility or liability for the fitment, function, or safety of any products modified in any way not expressly outlined in the installation manual.

Before Starting
Read this manual prior to beginning the installation to ensure familiarity with the components and how they will fit on the vehicle. Identify any variations from the application list such as vehicle model, engines, or optional equipment (e.g., dual alternator, active steering assist, etc.).
Open the package, unpack the components and identify them using the Illustrated Parts List (IPL) included in the Fastener Pack.

Hose Information
Depending on other installed equipment, it might be necessary to move the air/oil separation tank from its intended location. The hoses used in VMAC compressor systems have a specific inner liner that is compatible with VMAC compressor oil. Use of hoses other than those supplied or recommended by VMAC may cause compressor damage and may void your warranty. Please contact VMAC for replacement hoses and further information.

Ordering Parts
To order parts, contact a VMAC dealer. The dealer will ask for the VMAC serial number, part number, description and quantity. Locate the nearest dealer online at www.vmacair.com/dealer-locator or call 1-877-912-6605.

Special Tools Required

None.
All fasteners must be torqued to specifications. Use manufacturers’ torque values for OEM fasteners.

The torque values supplied in Table 1 are intended for VMAC supplied components, or for use as a guide in the absence of a torque value provided by an OEM.

Apply Loctite 242 (blue) to all fasteners (except nylon lock nuts) unless otherwise stated.

Torque values are with Loctite applied unless otherwise specified.

Voltage Sense Interlock

Installation and Operation

Installation
The Welder Control Box includes an 8 ft harness with (×4) plugs.

• Mount the Welder Control Box in a convenient location that is protected from the weather.
• Locate harness bundle with the connectors near the main air discharge from the MF.
• Plug one side of the “T” harness with the (×2) flat 5-pin connectors into the matching connector at the MF unit and the other side into the connector running to the rocker switches on the Display Panel.
• Connect the (×2) Welder Control Box connectors into the matching connectors in the main harness bundle.

Operation
This generator has been equipped with a voltage monitoring circuit to ensure that charging/welding voltages are operating correctly for the intended process.
The order of operations for connecting batteries or moving the system into weld mode must be followed exactly or the system disables itself and the generator must be reset.

Charging / Boosting Procedure

Working near lead/acid batteries is dangerous. Batteries contain sulphuric acid and may generate hydrogen gas during regular operation. Lead/acid batteries may explode if exposed to a spark.
Never attempt to jump start a frozen battery.
Never overcharge a battery.
Always follow safety precautions when jump starting or charging a battery, including the use of appropriate Personal Protective Equipment.

• Prior to charging or boosting, ensure the MF is not running, and the booster cables are disconnected from the battery to be charged.
• Set the “WELD” selection knob to 0 V.
• Start the MF.
• Engage the generator via the toggle switch located at the display box.
• The voltmeter should read approximately 0 V.

If “ErX” is displayed*:

• *Ensure the booster cables are not shorted together, or connected to the batteries to be charged, and the “WELD” selection knob is set to “0”.
• *Press and hold the “RESET” button for 2 seconds.
• Connect the positive clamp to the positive terminal on the battery.
• Connect the negative clamp to a good ground (ideally on the engine).

Observe the battery voltage using the Voltmeter*.

• *12 V systems should indicate battery voltage above 2.0 V.
• *24 V systems should indicate battery voltage above 14.0 V.

If the battery voltage is below the above values, the generator will not recognize the target and will not unlock the appropriate charge modes.

If the battery voltage is too low,*.

• Disconnect the battery from all loads. This may allow the battery voltage to rise high enough to be recognized by the system.
• If the battery does not recover adequate voltage after being disconnected, battery detection can be temporarily over-ridden by pressing and holding both the “RESET” and “BATTERY INTERLOCK” button for 5 seconds.

Once switched into charge mode, the system will re-enable battery detection after 60 seconds.

• With the battery connected, rotate the “WELD” selection knob to the appropriate charge mode*.
• The voltage should rise as the system begins charging.
• Set the “WELDING CURRENT” knob to 100%.
• Let the batteries charge for at least 5 minutes.
• Try starting the vehicle.

While the MF can provide up to 300 A of start assist, vehicle starters can draw upwards of 1,200 A while starting.
If the vehicle fails to start, allow it to charge for longer before attempting to start again.

• Return the “WELD” selection knob to 0 V.

Weld Procedure

• Prior to starting the MF, set the “WELD” selection knob to 0 V.
• Start the MF.
• Engage the generator via the toggle switch located at the display box.
• The voltmeter should read approximately 0 V.

If “ErX” is displayed*:

• *Ensure the weld cables are not shorted together, or connected to the batteries to be charged, and the “WELD” selection knob is set to “0”.
• *Press and hold the “RESET” button for 2 seconds.
• Press and hold the “WELD INTERLOCK” button while rotating the “WELD” selection knob to “WELD”.
• Adjust the “WELDING CURRENT” and “ARC FORCE” as required.
• Once welding is complete, set the “WELD” selection knob to 0 V (The “WELD INTERLOCK” button is not required when returning the “WELD” selection knob to 0 V).

Getting Started Guide

Read the warnings listed on page 9 prior to proceeding.

Troubleshooting

If the voltmeter detects a voltage or state that is not permitted, an error will be displayed on the screen.
If an error is displayed:

• Disconnect the target battery and ensure the booster, or weld cables are not shorted together.
• Return the “WELD” selection knob to 0 V.
• Press and hold the “RESET” button for 2 seconds.
• If the error persists, contact VMAC for support.
