LOCATION / VENTILATION
The welder should be located to provide an unrestrict- ed flow of clean, cool air to the cooling air inlets and to avoid heated air coming out of the welder recirculating back to the cooling air inlet. Also, locate the welder so that engine exhaust fumes are properly vented to an outside area.
STACKING
RANGER® 3 PHASE machines cannot be stacked.

The TIG Module is an accessory that provides high frequency and shielding gas control for AC and DC GTAW (TIG) welding. See IM528 supplied with the TIG Module for installation instructions.
NOTE: The TIG Module does not require the use of a high frequency bypass capacitor. However, if any other high frequency equipment is used, a Bypass Capacitor Kit (T12246) must be installed in the RANGER® 3 PHASE.

ADDITIONAL SAFETY PRECAUTIONS
Always operate the welder with the roof and case sides in place as this provides maximum protection from moving parts and assures proper cooling air flow.
Read and understand all Safety Precautions before operating this machine. Always follow these and any other safety procedures included in this manual and in the Engine Owner’s Manual.
WELDER OPERATION
WELDER OUTPUT
•Maximum Open Circuit Voltage at 3700 RPM is 80 Volts RMS.
•Duty Cycle is the percentage of time the load is being applied in a 10 minute period. For example, a 60% duty cycle represents 6 minutes of load and 4 minutes of no load in a 10 minute period. Duty Cycle for the RANGER® 3 PHASE is 100%.
