SPARK ARRESTER

Some federal, state or local laws may require that gasoline or diesel engines be equipped with exhaust spark arresters when they are operated in certain 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 K1898-1 must be installed and properly main- tained.

CAUTION

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

------------------------------------------------------------------------

HIGH FREQUENCY GENERATORS FOR TIG APPLICATIONS

The K930-2 TIG Module is suitable for use with the RANGER 305G. The RANGER 305G and any high frequency generating equipment must be properly grounded. See the K930-2 Operating Manual for com- pleted instructions on installation, operation, and maintenance.

REMOTE CONTROL

The RANGER 305G is equipped with a 6-pin and a 14-pin connector. The 6-pin connector is for connect- ing the K857 or K857-1 Remote Control (optional) or for TIG welding, the K870 foot Amptrol or the K963-3 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 305G automatically switches the OUTPUT control from control at the welder to remote control.

The 14-pin connector is used to directly connect a wire feeder or TIG Module (K930-2) control cable. In the CV-WIRE mode, the RANGER 305G auto-sensing circuit automatically makes the RANGER 305G 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.

ELECTRICAL CONNECTIONS

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 connected to premises wiring (home, shop, etc.)

To prevent dangerous electric shock, other equipment to which this engine driven welder supplies power must:

WARNING

•Be grounded to the frame of the welder using a grounded type plug.

•Be double insulated. Do not ground the machine to a pipe that carries explosive or combustible

material.

------------------------------------------------------------------------

When this welder is mounted on a truck or trailer, its frame must be electrically connected to the metal frame of the vehicle, use a #8 or larger copper wire connected between the machine grounding stud and frame of the vehicle. When this engine driven welder is connected to premises wiring such as that in a home or shop, its frame must be connected to the system earth ground. See further connection instruc- tions in the section entitled "Standby Power Connections" as well as the article on grounding in the latest U.S. National Electrical Code and the local code.

In general, if the machine is to be grounded, it should be connected with a #8 or larger copper wire to a solid earth ground such as a metal water pipe going into the ground for at least ten feet and having no insulat- ed joints, or to the metal framework of a building which has been effectively grounded.

The U.S. National Electrical Code lists a number of alternate means of grounding electrical equipment. A machine grounding stud marked with the symbol

is provided on the front of the welder.

WELDING TERMINALS

The RANGER 305G is equipped with a toggle switch for selecting "hot" welding terminal when in the "WELD TERMINALS ON" position or "cold" welding terminal when in the "REMOTELY CONTROLLED" position.
