IMPORTANT: To prevent ELECTRICAL DAMAGE WHEN:

a)Installing new batteries

b)Using a booster

Use correct polarity — Negative Ground.

The Commander is shipped with the negative battery cable disconnected. Before you operate the machine, make sure the Engine Switch is in the OFF position and attach the disconnected cable securely to the neg- ative (-) battery terminal.

Remove the insulating cap from the negative battery terminal. Replace and tighten the negative battery cable terminal.

NOTE: This machine is furnished with a wet charged battery; if unused for several months, the battery may require a booster charge. Be sure to use the correct polarity when charging the battery.

MUFFLER OUTLET PIPE

Remove the plastic plug covering the muffler outlet tube. Using the clamp provided, secure the outlet pipe to the outlet tube with the pipe positioned to direct the exhaust in the desired direction.

HIGH FREQUENCY GENERATORS FOR TIG APPLICATIONS

The K799 Hi-Freq Unit and the K930-1 or-2 TIG Module are suitable for use with the Commander 500. The Commander 500 is equipped with the required R.F. bypass circuitry for the connection of high fre- quency generating equipment. The high frequency bypass network supplied with the K799 Hi-Freq Unit does NOT need to be installed into the Commander 500.

The Commander 500 and any high frequency generat- ing equipment must be properly grounded. See the K799 Hi-Freq Unit and the K930-1 or-2 TIG Module operating manuals for complete instructions on instal- lation, operation, and maintenance.

ELECTRICAL CONNECTIONS

REMOTE CONTROL

The Commander 500 is equipped with a 6-pin and a 14-pin connector. The 6-pin connector is for connecting the K857 or K857-1 Remote Control (optional) or, in the case of TIG welding applications, with the foot or hand Amptrol (K870 or K963-1 respectively).

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 loca- tions where unarrested sparks may present a fire haz- ard. The standard muffler included with this welder does not qualify as a spark arrester. When required by local regulations, a suitable spark arrester must be installed and properly maintained.

CAUTION

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

The 14-pin connector is used to directly connect a wire feeder or TIG Module (K930-1 or-2) control cable.

NOTE: When using the 14-pin connector, if the wire feeder has a built-in power source output control, do not connect anything to the 6-pin connector.

WELDING TERMINALS

The Commander 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 "WELDING TERMINALS REMOTELY CONTROLLED" position.
