Note: The TIG Module does not require the use of a high frequency bypass capacitor. However, if the Ranger 8 is used with any other high frequency equip- ment, the bypass capacitor must be installed - order kit T12246.

INSTRUCTIONS

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.

CAUTION

Do not connect any plugs that connect to the power receptacles in parallel.

Start the engine and set the “IDLER” control switch to the desired operating mode. Set the “CONTROL” to

115/230 Volt Dual Voltage Receptacle

The 115/230 volt receptacle can supply up to 40 amps of 230 volt power to a two wire circuit, up to 40 amps of 115 volts power from each side of a three wire cir- cuit (up to 70 amps total). Do not connect the 115 volt circuits in parallel. Current sensing for the automatic idle feature is only in one leg of the three wire circuit as shown in the following column.
