    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.

  • Page 4

    WELDING 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 adjacent areas.

    Only qualified personnel should install, use, or service this equipment. 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.

  • Page 10: Pre-operation Engine Service, Additional Safety Precautions, High Altitude Operation, High Temperature Operation, Towing, Fuel

    • Be sure machine is stable when lifting. HIGH ALTITUDE OPERATION At higher altitudes, output de-rating may be necessary. For maximum rating, de-rate the welder output 3.5% for every 1000 ft. (305m). Contact an authorized engine service shop for modifications to operate above 5,000 ft.

  • Page 11: Electrical Output Connections, Battery Connections, Muffler Outlet Pipe, Spark Arrester

    The standard muffler included with this welder does not qualify as a spark arrester. When required by local regulations, a suitable spark arrester, such as the S24647, must be installed and properly maintained.

  • Page 12: Welding Output Cables

    When connected to premises wiring such as that in a home or shop, the welder frame must be connected to the system earth ground. See further connection instructions in the section entitled Standby Power Connections as well as the article on ground- ing in the latest U.S.

    WELDER OPERATION GENERAL INFORMATION WARNING • Do not touch electrically live parts or elec- trodes with your skin or wet clothing. • Do not breathe welding fumes or gases. • Use ventilation or exhaust to remove weld- ing from the breathing area.

    STICK WELDING The Ranger 250 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.

  • Page 23

    TIG WELDING The TOUCH START TIG setting of the MODE switch is for DC TIG (Tungsten Inert Gas) welding. To initiate a weld, the OUTPUT control is first set to the desired cur- rent and the tungsten is touched to the work. During the time the tungsten is touching the work there is very little voltage or current and, in general, no tungsten contamination.

  • Page 24

    B-10 The 240 VAC output can be split to provide two sepa- rate 120 VAC outputs with a maximum permissible cur- rent of 33 amps per output to two separate 20 amp branch circuits. (These circuits cannot be paralleled.) Output voltage is within ±10% at all loads up to rated capacity.

    THEORY OF OPERATION SOURCE DRAIN A. PASSIVE INSULATED GATE BIPOLAR TRANSISTOR (IGBT) OPERATION An IGBT is a type of transistor. IGBTs are semiconduc- tors 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.

  • Page 48

    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.
