OPERATION

CAUTION

DO NOT OPERATE SWITCHES ON CV ADAPTER WHILE WELDING.

VV OR CV WELDING (All Power Sources)

ANY LN-15, LN-22 AND LN-25 WIRE FEEDER OR

WARNING

CABLES ATTACHED TO CV ADAPTER OUTPUT TER- MINAL AND STANDARD OUTPUT TERMINALS ARE ALWAYS ENERGIZED WHEN ENGINE IS RUNNING REGARDLESS OF MODE SWITCH POSITION. STORE LN-15, LN-22 AND LN-25 GUN OR ELECTRODE HOLDER SO THEY DO NOT CONTACT WORK WHEN NOT WELDING.

VV STICK WELDING (All Power Sources)

Place both mode switches on the CV Adapter to VV Stick position. For units with remote control, place the Remote Control Switch in the desired position.

NOTE: THE UPPER SWITCH MUST IN VV POSITION BEFORE THE LOWER SWITCH CAN BE PLACED IN

VVPOSITION. An interlocking handle prevents operation of the switches in the wrong sequence.

Connect the welding cables to the standard output termi- nals of the engine welder and use the standard controls to set the welding current. On the SAE-300, SAE -400 and SAE-400 WELD’N AIR engine welders, the polarity switch is disconnected so the standard “To Work” terminal that has been relabeled “Positive” is always positive, and the standard “Electrode” terminal that has been relabeled “Negative” is always negative.

CV INNERSHIELD WELDING

(SA-200, SA-250, Classic I AND Classic II)

Place both mode switches in CV Innershield position.

NOTE: THE LOWER SWITCH MUST BE IN THE CV POSITION BEFORE THE UPPER SWITCH CAN BE PLACED IN THE CV POSITION. An interlocking handle prevents operation of the switches in the wrong sequence.

For electrode negative Innershield welding, connect the Wire Feeder to the output terminal on the CV Adapter and connect the work to the positive standard output terminal. For electrode positive, reverse the output leads.

(The Wire Feeder electrode lead is then connected to the positive standard output terminal.)

The negative standard output terminal is not used for CV welding of either polarity. Set the Wire Feeder polarity switch to same polarity that is required by electrode. Connect control lead from the Wire Feeder control box to work using the spring clip on the end of the lead.

The output voltage is set with the voltage control dial on the CV Adapter. Set the welder “Current Range Selector” to the 190-120 position for optimum welding characteris- tics with Innershield electrodes. Changing the “Current Range Selector” affects arc characteristics. The setting of the “Fine Current Adjustment” does not affect the opera- tion in “CV” mode.

When the CV Adapter is in the “CV” mode, the maximum auxiliary power on SA-250’s and Classic II’s with AC aux- iliary power will be reduced by 25%. To obtain maximum output, place both switches in “VV” position.

If the current rating of the welder is exceeded, a thermo- stat will reduce the output voltage to about 5 volts. The thermostat will reset automatically as the machine cools. If the thermostat trips, lower wire feed speed or duty cycle.

CV INNERSHIELD WELDING (SAE Engine Welders)

Place both switches in CV Innershield position.

NOTE: THE LOWER SWITCH MUST BE IN THE “CV” POSITION BEFORE THE UPPER SWITCH CAN BE PLACED IN “CV” POSITION. An interlocking handle pre- vents operation of the switches in the wrong sequence. For codes 10600 and above, the “Job Selector” Must be at maximum.

For electrode negative Innershield welding, connect the electrode lead of a Wire Feeder to the output terminal on the CV Adapter and connect the work to the “To Work” standard SAE output terminal that is relabeled “Positive”. For electrode positive, reverse the output leads. (The Wire Feeder electrode lead is then connected to the out- put terminal that is labeled “Positive”.) The standard SAE “Electrode” output terminal that is relabeled “Negative” is not used for CV welding of either polarity. Set Wire Feeder polarity switch to same polarity that is required by elec- trode. Connect control lead from the Wire Feeder control box to work using the spring clip on the end of the lead.

The output voltage is set with the voltage control dial on the CV Adapter. Set the SAE “Current Control” to the 9 o’clock position for optimum welding characteristics with Innershield electrodes. Changing the “Current Control” affects arc characteristics.

The setting of the “Job Selector” does not affect operation in “CV” mode on codes 8812 through 10400 only.
