OPERATION

B-4

 

 

 

CAUTION

Operating the starter motor for more than 5 sec- onds can damage the motor. If the engine fails to start, release the switch and wait 10 seconds before operation the starter again. Do NOT push the START button while the engine is running because this can damage the ring gear and/or the starter motor.

------------------------------------------------------------------------

NOTE: When starting a RANGER 305G for the first time, or after and extended period of time of not operat- ing, it will take longer than normal because the fuel pump has to fill the fuel line and carburetor.

STOPPING

Remove all welding and auxiliary power loads and allow the engine to run at low idle speed for a few min- utes to cool the engine.

Stop the engine by placing the RUN-STOP in the STOP position.

NOTE: A fuel shut off valve is not required on the RANGER 305G because the fuel tank is mounted below the engine.

WELDER OPERATION

DUTY CYCLE

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.

DC STICK WELDING

The RANGER 305G can be used with a broad range of DC stick electrodes.

The MODE switch provides two stick welding settings as follows:

CONSTANT CURRENT (CC-STICK) WELDING

The CC-STICK position of the MODE switch is designed for horizontal and vertical-up welding with all types of electrodes, especially low hydrogen. The out- put CONTROL dial adjusts the full output range for stick welding.

The ARC CONTROL knob sets the short circuit current during stick welding (arc-force). Increasing the number from -10 to +10 increases the short circuit current and prevents sticking of the electrode to the plate while welding. This can also increase spatter. It is recom- mended that the ARC CONTROL be set to the mini- mum number without electrode sticking. Start with the dial set at 0.

DOWN HILL PIPE WELDING

This slope controlled setting is intended for "out-of- position" and "down hill" pipe welding where the opera- tor would like to control the current level by changing the arc length. The output CONTROL dial adjusts the full output range for pipe welding.

The ARC CONTROL knob sets the short circuit current during stick welding (arc-force). Increasing the number from -10 to +10 increases the short circuit current and prevents sticking of the electrode to the plate while welding. This can also increase spatter. It is recom- mended that the ARC CONTROL be set to the mini- mum number without electrode sticking. Start with the dial set at 0.
