    ELECTRIC SHOCK can kill. 3.a. The electrode and work (or ground) circuits are electrically “hot” when the welder is on. Do not touch these “hot” parts with your bare skin or wet clothing. Wear dry, hole-free gloves to insulate hands.

    WELDING and CUTTING SPARKS can cause fire or explosion. 6.a. Remove fire hazards from the welding area.If this is not possible, cover them to prevent the welding sparks from starting a fire. Remember that welding sparks and hot materials from welding can easily go through small cracks and openings to adjcent areas.

    INSTALLATION LOCATION AND VENTILATION The welder should be located to provide an unrestrict- ed flow of clean, cool air to the cooling air inlets and to avoid restricting the cooling air outlets. Also, locate the welder so that the engine exhaust fumes are properly vented to an outside area.

    HIGH TEMPERATURE OPERATION At temperatures above 104°F(40°C), Welder output derating is necessary. For maximum output ratings, derate the welder out- put 2 volts for every 18°F(10°C) above 104°F(40°C). COLD WEATHER STARTING: With a fully charged battery and the proper oil, the engine should start satisfactorily down to -15°F(-26C°).

    THEORY OF OPERATION 4. ARC CONTROL - The ARC CONTROL dial is active in the CV-WIRE, CC-STICK and DOWNHILL PIPE modes, and has different functions in these modes. This control is not active in the TIG mode. CC-STICK mode: In this mode, the ARC CONTROL dial sets the short circuit current (arc-force) during stick welding to adjust for a soft or crisp arc.

  • Page 21: Engine Coolant

    THEORY OF OPERATION ENGINE CONTROLS: 12. RUN/STOP SWITCH - RUN position energizes the engine prior to starting. STOP position stops the engine. The oil pressure interlock switch prevents battery drain if the switch is left in the RUN position and the engine is not operating.

    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.

  • Page 23

    THEORY OF OPERATION The OUTPUT CONTROL dial adjusts the full output range for pipe welding. The ARC CONTROL dial sets the short circuit current (arc-force) during stick welding to adjust for a soft or more forceful digging arc (crisp). Increasing the number from - 10(soft) to +10(crisp) increases the short circuit current which results in a more forceful digging arc.

  • Page 24

    THEORY OF OPERATION • Set the "WELDING TERMINALS" switch to the "REMOTELY CONTROLLED" position. This will keep the "Solid State" contactor open and provide a "cold" elec- trode until the Amptrol or Arc Start Switch is pressed. When using the TIG Module, the OUTPUT CONTROL on the VANTAGE®...

    THEORY OF OPERATION INSULATED GATE BIPOLAR TRANSISTOR (IGBT) OPERATION An IGBT is a type of transistor. IGBTs are semicon- ductors well suited for high frequency switching and high current applications. Drawing A shows an IGBT in a passive mode. There is no gate signal, zero volts relative to the source, and therefore, no current flow.

    THEORY OF OPERATION FIGURE E.6 – TYPICAL IGBT OUTPUTS PULSE WIDTH MODULATION The term PULSE WIDTH MODULATION is used to describe how much time is devoted to conduction in the cycle. Changing the pulse width is known as MODU- LATION. Pulse Width Modulation (PWM) is the varying of the pulse width over the allowed range of a cycle to affect the output of the machine.

    THEORY OF OPERATION CHOPPER TECHNOLOGY FUNDAMENTALS The new era of welding machines such as the Vantage® 500, employ a technology whereby a DC source is turned on and off (chopped up) at high speed, then smoothed through an inductor to control an arc.
