Lincoln Electric IM700-D manual High Frequency Generators for TIG Applications, Remote Control

A-5 INSTALLATION A-5

MUFFLER

Remove the plastic plug covering the muffler outlet tube. Using the clamp provided secure the extension to the outlet tube. This welder is supplied with an adjustable rain cap for the muffler. Install the rain cap using the clamp provided with the outlet facing away from the direction in which this unit will be transported. This will minimize the amount of water and debris which could enter the muffler during transportation.

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, such as the S24647 must be installed and properly maintained.

CAUTION

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

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 300. The Commander 300 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 300.

The Commander 300 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.

REMOTE CONTROL

OUTPUT

The Commander 300 is equipped with a 6-pin & 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 K812 respectively).

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.
