Resumen del manual
For electrode Negative, connect the electrode cable from the LN-25 to the "-" terminal of the welder and work cable to the "+" terminal of the welder. 3. Attach the single lead from the front of the LN-25 to work using the spring clip at the end of the lead. This is a control lead to supply current to the wire feeder motor; it does not carry welding current. 4. Set the MODE switch to the "CV-WIRE " position. 5. Set the "WELD TERMINALS" switch to "WELD TERMINALS ON" 6. Set the "ARC CONTROL" knob to "0" initially and adjust to suit. 7. Set the "IDLE" switch to the "AUTO" position. When not welding, the AIR VANTAGE® 500 engine will be at the low idle speed. If you are using an LN-25 with an internal contactor, the electrode is not energized until the gun trigger is closed. 8. When the gun trigger is closed, the current sensing circuit will cause the AIR VANTAGE® 500 engine to go to the high idle speed, the wire will begin to feed and the welding process started. When welding is stopped, the engine will revert to low idle speed after approximately 12 seconds unless welding is resumed. CAUTION If you are using an LN-25 without an internal con- tactor, the electrode will be energized when the AIR VANTAGE® 500 is started. CONNECTION OF AN NA-3 AUTOMATIC WELDING SYSTEM TO THE AIR VAN- TAGE® 500 For connection diagrams and instructions for connect- ing an NA-3 Welding System to the AIR VANTAGE® 500, refer to the NA-3 Welding System instruction manual. The connection diagram for the LN-8 can be used for connecting the NA-3. • Set the Wire Feeder Voltage Switch to 115V. CONNECTION OF MAGNUM SC SPOOL GUN TO THE AIR VANTAGE® 500 (SEE SECTION F) Spool Gun (K487-25) and Cobramatic to AIR VAN- TAGE® 500 • Shut the welder off. • Connect per instructions on the appropriate connec- tion diagram in Section F. AIR VANTAGE® 500 CUMMINS B-1 B-1 OPERATION SAFETY PRECAUTIONS RECOMMENDED APPLICATIONS Read and understand this entire section before operating your AIR VANTAGE® 500. WARNING Do not attempt to use this equipment until you have thoroughly read the engine manufacturer’s manual supplied with your welder. It includes important safety precautions, detailed engine starting, operat- ing and maintenance instructions, and parts lists. ELECTRIC SHOCK can kill. • Do not touch electrically live parts or electrode with skin or wet clothing. • Insulate yourself from work and ground • Always wear dry insulating gloves. ENGINE EXHAUST can kill. • Use in open, well ventilated areas or vent exhaust outside • Do not stack anything near the engine. MOVING PARTS can injure. • Do not operate with doors open or guards off. • Stop engine before servicing. • Keep away from moving parts • Only qualified personnel should operate this equipment. • Always operate the welder with the sliding door closed and the side panels in place as these pro- vide maximum protection from moving parts and insure proper cooling air flow. GENERAL DESCRIPTION The AIR VANTAGE® 500 is a diesel engine-driven welding power source. The machine uses a brush type alternating current generator for DC multi-purpose weld- ing, for 240 VAC single phase. The AIR VANTAGE® 500 also has a rotary screw 60 cfm air compressor built in. The DC welding control system uses state of the art Chopper Technology for superior welding perfor- mance. The AIR VANTAGE® 500 provides excellent constant current DC welding output for stick (SMAW) and TIG welding. The AIR VANTAGE® 500 also provides excellent constant voltage DC welding output for MIG (GMAW), Innershield (FCAW), Outershield (FCAW-G) and Metal Core welding. In addition the AIR VAN- TAGE® 500 can be used for Arc Gouging with car- bons up to 3/8”(10mm) in diameter. The AIR VANTAGE® 500 is not recommended for pipe thawing. AIR COMPRESSOR The AIR VANTAGE® 500 provides 60 cfm at 100 psi. compressed air for Arc Gouging and Air powered tools. GENERATOR The AIR VANTAGE® 500 provides smooth 240 VAC single phase output for auxiliary power and emergency standby power. AIR VANTAGE® 500 CUMMINS B-2 B-2 OPERATION CONTROLS AND SETTINGS All welder and engine controls are located on the case front panel. Refer to Figure B.1 and the explanations that follow. FIGURE B.1 ENGINE CONTROLS (Items 1 through 9) 1. RUN STOP SWITCH Toggling the switch to the RUN position energizes the fuel solenoid for approximately 30 seconds. The engine must be started within that time or the fuel solenoid will deenergize, and the switch must be toggled to reset the timer. 2. START PUSHBUTTON Energizes the starter motor to crank the engine. With the engine "Run / Stop" switch in the "Run" position, push and hold the Start button to crank the engine; release as the engine starts. Do not press while engine is running since this can cause damage to the ring gear and/or starter motor. 3. ENGINE STOP SWITCH Shut’s down engine. 4. HOUR METER The hour meter displays the total time that the engine has been running. This meter is a useful indicator for scheduling preventive maintenance. 5...
