Lincoln IM985 Welder Operation, Stopping the Engine, Constant Current CC-STICK Welding, TAbLE b.2

b-7 OPERATION b-7

NOTE: If the unit fails to start turn Run/Stop switch to off and repeat step 3 through step 7 after waiting 30 seconds.

CAUTION

•Do not allow the starter motor to run continuously for more than 20 seconds.

•Do not push the START button while the engine is running because this can damage the ring gear and/or the starter motor.

•IF the Engine Protection or battery Charging Lights do “not” turn off shortly after starting the engine shut off the engine immediately and

determine the cause.

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

NOTE: When starting for the first time, or after and extended period of time of not operating, it will take longer than normal to start because the fuel pump has to fill the fuel system. For best results, bleed the fuel system as indicated in Maintenance Section of this manual.

STOPPING THE ENGINE

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

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

NOTE: A fuel shut off valve is located on the fuel pre-filter.

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.

ELECTRODE INFORMATION

For any electrode the procedures should be kept with- in the rating of the machine. For information on elec- trodes and their proper application see (www.lincoln- electric.com) or the appropriate Lincoln publication.

The AIR VANTAGE® 500 KUBOTA 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 OUTPUT CON- TROL dial adjusts the full output range for stick welding.

The ARC CONTROL dial sets the short circuit current (arc- force) during stick welding to adjust for a soft or crisp arc. Increasing the number from -10(soft) to +10(crisp) increas- es the short circuit current and prevents sticking of the electrode to the plate while welding. This can also increase spatter. It is recommended that the ARC CONTROL be set to the minimum number without electrode sticking. Start with the dial set at 0.

NOTE: Due to the low OCV with the VRD on, a very slight delay during striking of the electrodes may occur. Due to the requirement of the resistance in the circuit to be low for a VRD to operate, a good metal- to-metal contact must be made between the metal core of the electrode and the job. A poor connection anywhere in the welding output circuit may limit the operation of the VRD. This includes a good connec- tion of the work clamp to the job. The work clamp should be connected as close as practical to where the welding will be performed.
