WARNING

BATTERY ACID CAN BURN EYES AND SKIN.

•Wear gloves and eye protection and be careful when working near a battery. Follow the instructions printed on the battery.

Use caution as the electrolyte is a strong acid that can burn skin and damage eyes.

The Ranger 250 is shipped with the negative battery cable disconnected. Make certain that the RUN-STOP switch is in the STOP position. Remove the screws from the rear battery tray using a screwdriver or a 3/8" socket. Attach the negative battery cable to the nega- tive battery terminal and tighten using a socket or wrench.

NOTE: This machine is furnished with a wet charged battery; if unused for several months, the battery may require a booster charge. Be careful to charge the bat- tery with the correct polarity. See the battery charging instructions in the Maintenance section.

MUFFLER OUTLET PIPE

Using the clamp provided, secure the outlet pipe to the outlet tube with the pipe positioned to direct the ex- haust in the desired direction. Tighten using a socket or wrench.

SPARK ARRESTER

Some federal, state or local laws may require spark arresters in locations where unarrested sparks may present a fire hazard. 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. See the Accessories section for more information.

The K930-2 TIG Module is suitable for use with the Ranger 250. The Ranger 250 and any high frequency generating equipment must be properly grounded. See the K930-2 operating manual for complete instruc- tions on installation, operation, and maintenance.

REMOTE CONTROL

The Ranger 250 is equipped with a 6-pin and a 14-pin Amphenol connector. The 6-pin connector is for con- necting the K857 or K857-1 Remote Control (optional) or for TIG welding, the K870 foot Amptrol or the K963- 2 hand Amptrol.

When in the CC-STICK, PIPE, and CV-WIRE modes and when a remote control is connected to the Amphenol, the auto-sensing circuit in the Ranger 250 automatically switches the OUTPUT control from con- trol at the welder to remote control.

The 14-pin connector is used to directly connect a wire feeder. In the CV-WIRE mode, the Ranger 250 auto- sensing circuit automatically makes the Ranger 250 OUTPUT control inactive and the wire feeder voltage control active when the control cable is connected to the 14-pin connector.

NOTE: When a wire feeder with a built in welding volt- age control is connected to the 14-pin connector, do NOT connect anything to the 6-pin connector.

WELDING TERMINALS

The Ranger 250 is equipped with a toggle switch for selecting “hot” welding terminals when in the “WELD TERMINALS ON” position or “cold” welding terminals when in the “REMOTELY CONTROLLED” position.

CAUTION

An incorrect spark arrester may lead to engine damage or may adversely affect performance.

MACHINE GROUNDING

Because this portable engine driven welder

creates its own power, it is not necessary to connect its frame to an earth ground, unless the machine is con- nected to premises wiring (home, shop, etc.)
